PSPICE SCHEMATICS MOVING SIMULATION SERIES

Fourier Output: Fourier output now supports NUMDGT.

Subcircuit Definition: Subcircuit definitions in OrCAD PSpice environment can now support any character length.

This chapter explains the steps required to add your own content, lessons, or app notes to OrCAD PSpice environment

Learning OrCAD PSpice Technology and Adding Your Own Content: A new chapter is available in the Learning OrCAD PSpice module.

Additional heuristic algorithms will be added under this option in subsequent releases An example of such an algorithm is to reject the last successful time point and start working out the simulation solutions from the time point previous to the last successful time point.

PSPICE SCHEMATICS MOVING SIMULATION SERIES

Enable Continuation Methods: This series of transient convergence methods allows OrCAD PSpice simulator to override default solution search schemes and apply other heuristic algorithms, and is applied when all other options have failed.While a default value of 1.0E-12 is recommended, it can be changed on a case-by-case basis

The OrCAD PSpice 16.6 QIR 3 provides a CSHUNT option that adds capacitors of specified value to the nodes. Successive iterations within OrCAD PSpice solver result in node oscillations and convergence errors.

CSHUNT On/Off Option: In a number of cases, the nodes values do not stabilize because one or more feedback path has no delay in path.

'10p files for Convergence Failure' Option: This option allows the operating point values even if a convergence failure has occurred, thereby avoiding situations where the user is left with previous bias point values on convergence failure.

New options are available to set a minimum parasitics value level for diodes and Bipolar Junction Transistors (BJT) globally. For example, using an ideal diode with parasitics can lead to convergence and performance issues as the simulator quickly moves to very small timesteps and often goes over minimum timestep thresholds.

Option to Apply Parasitics Globally: On analysis of a large number of OrCAD PSpice designs, it was found that a number of issues were caused by ideal devices (without parasitics).

OrCAD Capture Simulation Parameters: New Probe statement supports P() function to capture parameter values in.

dat File Post Processing: TCL function support in circuit file allows automated post-processing of any PSpice output file

Expression Support: Now available forВ the.

Global Parasitics Support Convergence Option: Ability to set minimum parasitics for the following devices.

New Convergence Options: The following convergence options are now available in.

Option to Ignore DML Error: New option in the IBIS2Spice command to DML checks and attempt at translating to Spice.

Used to quickly define commands not available through standard PSpice setup GUI

Comments as OrCAD PSpice Directives: All comments in the Capture canvas starting with are net-listed into the.

Complete theory and design with examples included.

Learning PSpice Update: Added a new Power Electronics module.

Frequency Response Analysis: New method to calculate open loop gain for switching circuits from transient analysis using Middlebrook's Method (blog article).

Object Distribution Feature:В Enhanced to force equal spaced distribution by default.

The symbol viewer within the Searcher has also been updated.

Enhanced PSpice Model Search Utility:В Now PSpice Advance Analysis libraries, such as, aa_igbt.olb, and so on are added to the PSpice Part Search database so you are able to search and then place in your designs.

This is user customizable and there is a TCL source available in the installation hierarchy.

New Simulation Reporting Capabilities:В Users are now able to generate an HTML report for Analog Transient simulation where average, RMS, and Peak values of Current, Voltage, and Power can be reported.

Hysteresis Core Loss Calculator:В Users can now use this app that measures Steady State loss of energy in a magnetic core for power supplies.

This will help to eliminate performance and mathematic errors.

Convergence Improvements:В With QIR7 improvements, users are recommended to use lower values of ITL4 to achieve convergence and performance compared to previous releases requiring high ITL4 values using Switches circuits to achieve convergence.

Enhanced Multicore Support:В Removed multi-core usage limit (previously maxed out at 4 cores).The speed levels will allow for faster switching of devices and show substantial improvement from the previous release. Speed Upgrades:В Users can take advantage of the 5 levels of speed upgrades with the default set at a level 3, (speed level should be set at 0 for compatibility with previous releases).PSpice Learning Resources Update:В Users can use the new Digital Electronics and Data Convertors chapters with working examples that have been added to the Basic Electronics book in Learning PSpice.
