optimizeRun() tutorial?

markbeck

Does anyone out there know of a tutorial that shows how to use the optimizeRun command (and supporting commands)?

I'm trying to create an ocean script for running optimizations, but when I try to run it I'm getting errors..

e.g.:  *Error* eval: undefined function - ocniOptVariables

Never heard of it, and it doesn't show up in the finder.

 Thanks,

Mark

  • Hi Mark,

    Tawna asked me to jump in here for a moment, as I do a lot of work with the ADE XL and GXL (optimization, etc.) technology .  In IC 6.1, optimization falls under ADE GXL.  The engines have been significantly enhanced and offer several powerful algorithms.  The optimizer works from an ADE XL test setup and supports multiple testbenches, specifications and corners.  It can optimize a large number of design parameters over a wide variety of measurements.  Hence, the OceanXL script you found.  It sets up the tests, corners, measurements, specs and variables and then runs local optimization.

     I would say your best bet for learning this technology would be to start off using it from the GUI, saving the resulting setup to an OceanXL script and working from there.  There are several new videos in the Video Library at http://support.cadence.com which show you how to set up and run simulations, specifications, sweeps and parameterization in ADE XL.  After that, optimization is essentially just a matter of setting the Run Mode to Local or Global Optimization and hitting the run button.
