OrCAD 16.6 QIR #7 What's new
The newest OrCAD® 16.6 Quarterly Incremental Release, QIR#7, was released on July 25th and is now available from your local Cadence Channel Partner. Check out what’s new! Quarterly Incremental Releases (QIRs) deliver new OrCAD features in-between major releases. This accelerated release process was introduced in the 16.6 release. QIR updates are available to all customers on maintenance.
Significant PSpice Performance Enhancements
Along with substantial improvements in simulation and engine optimization, new speed levels allow faster switching of devices during simulation resulting in substantial speed improvements. In designs with switches, simulation performance improvements up to 5x can be expected.
Unleash the Power of Multi-core Simulation
Helping to improve performance, there is no limit on the number of processor cores or threads that can be utilized during simulation. Beyond general performance improvements, multi-core simulation significantly boosts performance for larger designs and those with complex model instances; like MOSFETS, BJTs.
Extensive Simulation Convergence Improvements
Eliminating convergence errors has been a major focus of recent QIR releases for PSpice. User-configurable convergence options, engine optimizations, and new continuation schemes have helped reduce convergence failures by up to 80%. For QIR#7, higher ITL4 values (which had the potential to degrade performance as well as increased probability of numerical overflows) are no longer needed to help avoid convergence errors. Lower values of ITL4 can now be used.
Hysteresis Core Loss App for PSpice
The new Hysteresis Core Loss application measures Steady State loss of energy in a magnetic core for power supplies. The app calculates hysteresis core loss using the B-H loop area from the simulation result, the volume of the core, and the frequency of the operation.
