  • PSpice Learning Resources Update: 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.

  • Speed Upgrades: 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). The speed levels will allow for faster switching of devices and show substantial improvement from the previous release.

  • Enhanced Multicore Support: Removed multi-core usage limit (previously maxed out at 4 cores).

  • Convergence Improvements: 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. This will help to eliminate performance and mathematic errors.

  • New Simulation Reporting Capabilities: 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. This is user customizable and there is a TCL source available in the installation hierarchy.

  • Enhanced PSpice Model Search Utility: 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. The symbol viewer within the Searcher has also been updated.

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

OrCAD PSpice Designer - 16.6 QIR#4
  • Frequency Response Analysis: New method to calculate open loop gain for switching circuits from transient analysis using Middlebrook's Method (blog article)
  • Learning PSpice Update: Added a new Power Electronics module. Complete theory and design with examples included. Accessible through Help>Learning PSpice
  • Comments as OrCAD PSpice Directives: All comments in the Capture canvas starting with @PSpice are net-listed into the .cir file. Used to quickly define commands not available through standard PSpice setup GUI
  • Option to Ignore DML Error: New option in the IBIS2Spice command to DML checks and attempt at translating to Spice.
  • New Convergence Options: The following convergence options are now available in .OPTIONS
    • PREORDERMODE
    • MINSIMPTS
    • RMIN
    • BPPseudoTran
    • TRANCONV1

  • .dat File Post Processing: TCL function support in circuit file allows automated post-processing of any PSpice output file
  • OrCAD Capture Simulation Parameters: New Probe statement supports P() function to capture parameter values in .DAT file
OrCAD PSpice Designer - 16.6 QIR#3
  • 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). 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. New options are available to set a minimum parasitics value level for diodes and Bipolar Junction Transistors (BJT) globally.
  • "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
  • 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. Successive iterations within OrCAD PSpice solver result in node oscillations and convergence errors. The OrCAD PSpice 16.6 QIR 3 provides a CSHUNT option that adds capacitors of specified value to the nodes. While a default value of 1.0E-12 is recommended, it can be changed on a case-by-case basis
  • 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. 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. Additional heuristic algorithms will be added under this option in subsequent releases
  • Learning OrCAD PSpice Technology and Adding Your Own Content: A new chapter is available in the Learning OrCAD PSpice module. This chapter explains the steps required to add your own content, lessons, or app notes to OrCAD PSpice environment

  • Probe .dat Upgrade to 64-bit Precision: OrCAD PSpice technology now generates 64-bit data precision in the .dat file output. This ensures higher precision compared to the 32-bit .dat file data from previous releases. (As an example, in previous releases, when a very small amplitude voltage is superimposed on a large voltage, the resulting voltage lost its resolution in a 32-bit .dat file.)
  • UNDO Support for Captured Netlists: Netlisting to OrCAD PSpice environment now preserves UNDO, making it easier to make iterations and modify parameters, components, and connectivity
  • Enhanced IBIS Support: The IBIS to OrCAD PSpice model now supports V-T curves for all IBIS models up to version 5.0
  • Multi-core Engine Support: Enhancements to multi-core support and I/O read-write provide significant performance improvements. Focused performance enhancements, especially for large designs or designs with complex model instances (MOSFETS, BJT), also boost performance
  • Encryption Enhancements: Upgraded model encryption now includes 256-bit (AES) encryption support
  • Tcl-based Customization: Advanced Analysis, simulation, and .dat file access can be accessed and extended with user-definable actions and capabilities. This enables an environment that can be enhanced to specific flows and needs, and allows users to leverage enhanced features and design capabilities
