Engine Options

• Performance of Multi-Core enabled – Focused performance

enhancements for large designs with complex model instances like MOSFETS, BJT

• I/O Performance – Significant

performance for large DAT files

New PSpice Options – Speed

• THREADS

– Maximum number of threads to be used for simulation

– THREADS = 1 => Single-threaded simulation

– THREADS = 0 => Use default calculation

– By default, number of threads is calculated based on

device count, number of cores in the machine, and

PSpice license.

– Default thread count is <= number of cores/2

– Maximum 4 threads can be used for regular PSpice

Licenses

Enhanced PSpice Engine Options

• Convergence Improvement Options – Advanced Biaspoint Convergence

Homotopies

– Integration method option

– Node Value Limiting

– Relative Tolerance

• Accuracy Improvement Options – Worst-case control independent of

RELTOL

– Behavioral sources TimeStep Control for sinusoidal functions

– MinStep independent of TSTOP

– 64-Bit Data accuracy

Accuracy

• PROBE64 – 64-bit Probe data

– Increases resolution of probe

– Very useful for differential probes

• NOGMINI – Suppress GMIN addition across current sources

– Gives more accurate results for very low current values

• BRKDEPSRC – Sets automatic break-points for sinusoidal behavioral sources

– Useful for long simulations when default Max Time Step is too big

Enhancement for behavioral sources

• VT Tables

– Optional parameter for Table-driven behavioral

sources

– Tells simulator that x-axis of the Table represents

Time

Enabling Marketplace Applications •Integrate PSpice with any 3rd Party Applications

•Access PSpice Data and create plots e.g. using

Google Plot

•Write your own PSpice DAT file Browser

•TCL adds Expression support for AA

•Run multiple AA analysis for different values

without netlisting

•Pluggable Library Viewers

•Customize Algorithms – examples…

•Run Monte Carlo at different

Temperatures

•Tolerance any parameter in simulator

•Program PSpice to map any user

parameter to AA parameter for all designs

•Program PSpice to use common user

equations for all designs
