• 5 levels of speed upgrades – Default speed level is 3 – Speed level 0 should be set for
compatibility with previous releases
• Removed multi-core usage limit and default multi-thread usage – Previous releases used 50% of the
available threads up to four cores
• Speed levels allows faster switching of devices and shows substantial improvement – In test cases with switches, more
than a 5x performance improvement has been measured at level 3
Speed Upgrades
Significant upgrade in PSpice performance
![Page 13: What’s New – OrCAD 16.6 Quarterly Incremental Release #7 QIR7... · • Fix conditions for PSpice returning incorrect results for certain circuits − Re-simulation − Biaspoint](https://reader034.vdocument.in/reader034/viewer/2022050716/5e16414e5407cc5b7d5a7260/html5/thumbnails/13.jpg)
• Previous releases required a high ITL4 values when using Switches circuits to achieve convergence – At low ITL4 values, convergence errors
were observed – At high ITL4 values, performance and
mathematic errors were frequently observed
• With QIR7 improvements, it is recommended to use lower values of ITL4 to achieve convergence and performance – Note: using SPEED_LEVEL=0 will
require high ITL4 values to converge
Convergence Improvements
Designs with Switches converge at
lower ITL4 values
