It depends on the spice package you have. I use Microcap it's much more friendly and fast than most of spice packages I tried before. You can download a student free version (with some limitations but you have small circuits).

A new problem is that only 7 pins are defined on the electrical symbols for the op-amps but the package has 8 pins. You might hope that the software would assume that undefined pins are not connected but it does not: It must be told this formally.


OrCAD PCB Designer Professional with PSpice

Learn to design a circuit with PSpice is a task quite simple and is enough a few pages of any manual available on line to do it. What can be confusing is the number of files with different extensions that belong to this great tool of electronic simulation. This is due to the history of PSpice, which initially developed to be used in PC by Microsim passed after to OrCAD which was at last acquired by Cadence. The original CAD Microsim was Schematics. After, the program was provided with a design tool more advanced, Capture, maintaining the ability to still use Schematics.

Check the search paths if PCB Editor complains that it can’t find components. This shouldn’t occur if you use the standard libraries but may arise with local libraries.


We are doing simulation in OrCAD PSPICE and we are facing problem with (https://dkluchezar.ru/hack/?patch=1454) acquiring the results. We are getting "Out of Memory Error", even after using a 16GB memory system. So is it like a compromise between "Memory versus Accuracy". How can I get a waveform without losing any accuracy with the same memory conditions?

OrCAD PSpice (https://dkluchezar.ru/hack/?patch=4084) is used for simulation and verification for circuit. PSpice is stands for Personal Simulation Program with Integrated Circuit Emphasis. Capture and PSpice make complete simulator and PCB designing tool. PSpice is also available in two versions; PSpice Designer and PCB Designer plus. PSpice Designer is for industry-standard simulation and contains 33000 parts in the library. This version is starting from 1980 USD. PSpice designer plus is to analyze for reliability, cost, and yield. This version has all features of PCB designer and other unique features like cost analysis, yield analysis, design optimization, system C/C++ modeling and simulation, reliability analysis and HW/SW co-simulation.


Improved capture integration with the ability to view PSpice models within Capture

I don't fully understand your question. Are you asking if it's used in industry?

The book includes the latest features in the OrCAD (https://dkluchezar.ru/hack/?patch=1519) 17/2 release and there are exercises with (https://dkluchezar.ru/hack/?patch=9729) step by step instructions at the end of each chapter that enables the reader to progress based upon their experience and knowledge gained from previous chapters. The author worked for Cadence for over eight years and supported and delivered OrCAD PSpice training courses all over Europe. This book has been endorsed by Cadence.


It includes an automatic router that works out the arrangement of tracks needed to connect the com- ponents on the PCB. The output from PCB Editor is a plot or a set of files that can be sent to a manufacturer.

I also came across SwitcherCAD III. The circuit analysis is quite easy to use. I'll test it more to see how well it compares with Orcad PSpice (https://dkluchezar.ru/hack/?patch=2264).


To help students with the learning process, we offer a free version of PSpice via the OrCAD Academic Program

This document introduces the basic features of OrCAD PCB Designer. It is aimed primarily at novices with limited experience of construction who have never designed a PCB before. For this reason I concentrate on pin-through-hole devices (although surface-mount devices are no more difficult) on single and double-sided boards. I strongly recommend Mitzner’s book instead if you are an experienced designer, interested in more advanced PCBs for commercial production.

High voltage Power Amplifier SPICE models

The are many benefits to learning how to use the SPICE simulation software, primarly ,once you have modeled a circuit, you can easily change components and see immediately how its behavior changes. Furthermore, together with PCB editor tools, SPICE has become the standard in electronics industry, speeding up large-scale production.


This laboratory manual for students of Electronics, Electrical, Instrumentation, Communication, and Computer engineering disciplines has been prepared in the form of a standalone text, offering the necessary theory and circuit diagrams with each experiment. Procedures for setting up the circuits and measuring and evaluating their performance are designed to support the material of the authors' book Analog Electronics (also published by PHI Learning). There are twenty-five experiments. The experiments cover the basic transistor circuits, the linear op-amp circuits, the active filters, the non-linear op-amp circuits, the signal generators, the voltage regulators, the power amplifiers, the high frequency amplifiers, and the data converters. In addition to the hands-on experiments using traditional test equipment and components, this manual describes the simulation of circuits using PSPICE as well. For PSPICE simulation, any available standard SPICE software may be used including the latest version OrCAD V10 Demo software. This feature allows the instructor to adopt a single laboratory manual for both types of experiments.

The symptoms are that the Netlist Files Directory does not show as allegro automatically in figure 4 and that nothing happens when you run the netlister – not even an error mes- sage. Netlisting for PCB Editor must be performed once on each computer by a user with administrator privileges before it will work for anybody else.


Use GND from CAPSYM for the ground (earth) symbols. These symbols must have the same name throughout your drawing or they will not be linked.

Figure 18. My one-sided layout after autorouting. The total routed length was 29/300. The footprints are not taken from the Cadence library.


Draw the circuit shown in figure 2. The names of the components are listed in table 1; I’ve renamed some of them to make their functions clearer. I assume that you are familiar with Capture but here are a few tips to help.

Return to your drawing and correct any errors, shown by green circles (a strange choice of colour). Repeat until the Design Rules Check runs silently.


Here is a detailed list of topics covered in each section: 2 STARTING A PROJECT

The simplest way of creating a PCB is first to set up an empty PCB, then to add your compo- nents and connections to the board. This follows the design flow shown in figure.

Check the Session Log if this happens. Messages about RVMAX and CMAX can be ignored; these are maximum voltage ratings of the components and are not important for this circuit.


This design cannot be saved in the demonstration version of PCB Editor, which is limited to 10 components. Try omitting the decoupling capacitors, R1 and R3.

Problem with component/library in OrCAD PSpice

Select Start > Programs > OrCAD 16/2 > OrCAD Capture. I use ‘>’ throughout this document to show the levels of a hierarchical menu. There will be a short delay while the software is loaded and the licence server is accessed. Alternatively, you will be asked if you wish to use Demo mode if no licence can be found. The screen then shows the OrCAD Capture main window with a menu bar and various toolbars. A sub-window at the bottom shows the session log; its title may be hard to find if the window has been docked. Version 16/3 offers different ways of controlling the windows; right-click in a title bar.


Problem with Pspice simulation of Hartley oscillator

The second design is an instrumentation amplifier based on three op-amps, shown in figure 11. In practice it is unlikely that the circuit would be built using three sepa- rate packages with single op-amps as in this design. Complete instrumentation amplifiers are available in 8-pin packages. Even if these were unsuitable, a quad package that contains four op-amps could be used although these lack the pins for trimming the offset voltage.

Need help with OrCAD PSPICE Simulation

You can use any form of SPICE SUCH AS PSPICE, EWP, ORCAD (https://dkluchezar.ru/hack/?patch=3492) OR ICAPS. You can study the timing by applying the right clock signals on the logic gate. There are many model levels for the same device to analyse large circuits with simplified models.


Quick Solutions to Solve SPICE Convergence Issues

Leave Smart selected and click OK. The autorouter works away and you will see Message: Smart_route finished, completion rate: 100/00% if all is well. The tracks should be in colour if they are routed successfully, yellow for the bottom. Sometimes they are drawn white, which should indicate a design rules error, even when they are correct – I don’t know why.

SPICE Modeling of tapped air cored inductors

Two approaches are available for routing the board automatically, both shown in figure 1: Everything can be done from within PCB Editor or you can run the router as a separate application. The first is more convenient but the second offers finer control.


Items 1-4 above should be provided in report format, with figures and tables inserted into a MSWord document. All figures and tables should be accompanied by a figure caption and explanatory text describing the result(s) shown. For each section, your MbreakN and MbreakP model parameters must be clearly identified. For Part 1, discuss the voltage transfer characteristics of your inverter before and after optimization. Based on the noise margins calculated for Parts 1 & 2, comment on whether the output of your circuit could be used as an input for another identical circuit.

Run a Design Rules Check and correct any errors. Print your schematic when it has been completed and survived the DRC.


The main task in preparing the design for layout is to associate a footprint with each com- ponent. The footprint shows the physical outline of the components including the copper pads to which the pins are soldered. Most pads are either circular or oval except for pin 1, which has square corners to identify it. The components in many Capture libraries have footprints already but unfortunately they are mostly wrong. We must therefore enter the correct footprints, which are listed in table 1 for this circuit. Don’t muddle the letter ‘o’ with the numeral ‘0’. The whole business of assigning footprints is unnecessary if you have a database of components in Capture CIS.

Design rules are required to lay out the circuit on the PCB. The full details are complex but the basic rules specify the minimum width of tracks and the gap between them.


Layout automatically displays the components on screen, ready for you to move on the PCB. Allegro does not do this: You must place them yourself.

Power tracks are usually made wider than signal tracks because they have to carry more current. Our tracks are already so wide that it’s barely necessary but we’ll do it for future reference.

Specify the Route keepin distance as 100. A keepin means that objects must be kept inside the specified region.

Include a cover page for the final version of your project report. I will accept electronic (email) or physical submissions. Color prints are not required unless it makes your plots easier to interpret. If choosing to print the assignment, you may want to invert the colors on the PSPICE outputs to conserve ink/toner.


OrCAD Capture release 16/3 continues to boost productivity through new GUI updates, 3-D footprint viewing, a new auto-wire connection capability, and enhanced scripting with TCL/TK support. Cadence OrCAD Capture CIS release 16/3 provides more control and visibility over the relational data from the CIS database, and contains all the productivity and usability improvements highlighted in OrCAD Capture.

Links to SPICE libraries

Most PCBs need to be mounted inside a piece of equipment and therefore need holes for fixings. Mounting holes and similar features are called mechanical symbols and are placed in a slightly different way from electronic components because they are not part of the netlist.


The substantial abilities of OrCAD PSpice Probe allow you to make intricate measurements, cross-probe with the circuit style, view waveforms in several plots, and supply you with a broadened set of mathematical functions to use to simulation output variables. OrCAD PSpice Probe likewise makes it possible for the measurement of efficiency attributes of a circuit utilizing integrated functions and the production of customized measurements. OrCAD PSpice innovation is perfectly incorporated with OrCAD Capture– among the most commonly utilized schematic style services– permitting you to quickly cross-probe in between the schematic style and simulation plot outcomes and measurements. This combination likewise permits you to utilize the very same schematic for both simulation expedition and PCB design, decreasing rework and mistakes.

The Output Board File usually shows something sensible automatically; edit it if not. It should use the new allegro directory.


Getting Started with Micro-Cap SPICE software

Enter 25 for the Minimum Line width (in mils). This value propagates into the other boxes. It means 0/02500 or about 0/64 mm, which is very wide for a track nowadays but makes the board easy to solder by hand.

The screen then shows the OrCAD Capture main window with a menu bar and various toolbars

Your project will now be created. The Project Manager window at the top left shows the files associated with your design and the resources used, such as library files. Its title is the full pathname of your project, which is usually far too long to fit. Make the File tab active if necessary.


Click Start Allegro PCB Router to dismiss the box. PCB Router starts and you should now see your components joined by the ratsnest within the outline of the route keepin as in figure 16. Some components have shaded footprints, which I’ll explain later.

Turn routing off for the top layer by clicking on the drop-down menu next to TOP as shown in figure 17 and selecting the symbol. You might like to experiment with the setting of the BOTTOM layer. The directions are hints to the router but in practice tracks are drawn in both directions. Click Close when you have finished.

Use the manual equivalent of the flow described in the previous section if automatic routing does not work from PCB Editor. It’s a bit clumsier but gives better control over the process and makes it easier to experiment with different settings.

The SPICE modelling tool is typically used in the development of electrical and electronic circuits

Through several screens to define the parameters of the PCB. Some of these are obvious, such as the size of the board, while others set up the design rules – the width of tracks on the PCB, how much space must be left between them, and so on.


The positive pin is shown as a circle on the left. Select it and and choose Edit > Proper- ties. This brings up the Pin Properties dialogue box, shown in figure 3.

SPICE Analog circuit simulator

Could you share your design database? I can not think of any reason for this error from your post.


Do you use Orcad Capture to enter schematics? Or do use legacy "Schematics" from Microsim.

Power supply rails are normally hidden to simplify schematic drawings. Here the power pins of the opamps are connected to named power symbols. Capture considers all power sym- bols with the same name to be connected together.


Incompatibilities between Capture and PCB Editor must again be corrected before making the netlist. First, the pins of the electrolytic capacitors are wrongly numbered.

Getting Started with TINA

Tip for Layout users: PCB Designer comes with a small library of footprints compared with the extensive libraries that were provided with Layout. I’ve been told that this is because most users have their own libraries. Where there is a need, somebody will offer a service: Online libraries of footprints are available – for a fee.


Texas Instruments long offered TINA, but recently they’ve joined with Cadence to make OrCAD PSpice available for free with some restrictions. You’ve probably heard of PSpice — it’s widely used in academia and industry, but is usually quite costly. You can see a promotional overview video below.

OrCAD EE PSpice (find more info) is a SPICE circuit simulator application for simulation and verification of analog and mixed-signal circuits. PSpice (visit our website) is an acronym for Personal Simulation Program with Integrated Circuit Emphasis.


An example of modifying the transistor model is shown in the PSPICE tutorial on MOSFETs uploaded to e-campus. Determine the noise margins of the inverter.

Further information is needed to describe the characteristics of the printed circuit board on which the components are mounted. The details are important for high-speed designs but we need to know only the number of layers of copper, called etch in PCB Designer. This tutorial covers only single-sided boards, which have components on top and copper on the bottom, and double-sided boards, which have copper on both surfaces but usually components only on the top. Fancier boards often have two internal planes of copper used for power and ground; complex designs need further layers.


Select Use smart router for the Strategy. For a single-sided board deselect the box next to the TOP Routing Subclass. You might wish to experiment with the Routing Direction for the bottom layer. Click Route and wait for the results to come back. Use the Results button to get a report on the routing and check the Completion percentage to ensure that all nets were routed successfully.
