The Allegro AMS Simulator (analog/mixed-signal) 16.6 release adds several enhancements to the Advanced Options dialog form. This enables the customizability of a PSpice simulation run, including control over convergence homotopy options, making worst-case analysis independent of RELTOL and enabling auto-convergence automatically in case of convergence failure. These options do not change the core behavior of the simulator, but provide the designer new ways to control the behavior at different simulation points.
Options have been added to the Advanced Analysis Options dialog box in the following areas:--Bias-Point Convergence--Integration Method--Voltage Limiting--Worst-case Deviations--Max-Time Step Control--Pseudo Transient--Relative ToleranceRead on for more details…Here are the new options available in the Advanced Analog Options form:
Convergence Improvement Options:– Advanced Biaspoint Convergence Homotopies– Integration method option– Node Value Limiting– Relative ToleranceAccuracy Improvement Options:– Worst-case control independent of RELTOL– Behavioral sources TimeStep Control for sinusoidal functions– MinStep independent of TSTOP– 64-Bit Data accuracy
For the Biaspoint Convergence:
For the Transient Convergence:
There are also new PSpice Options:
I look forward to your feedback!Jerry “GenPart” Grzenia
You can install the free OrCAD PCB Designer Lite DVD found on www.cadence.com/.../downloads.aspx This will allow you to open up Capture schematics and view them. There is a design size limit, but it should work for most designs.
Is there a free Orcad schematic viewer like the Allegro pcb design viewer?
