annotate from dc sweeping sim

DavidLou

hello experts,

just wondering when I annotate from dc sweeping simulation (e.g., sweeping by temperature from -40 to 125 degree), how I specify to annotate device operating points at temperature of 0, or 25, or 85 degrees? is that doable from ADE and/or Ocean script?

thanks,

David

    Hi David,

    I'm assuming  you're using ADE L (you didn't say). If so, you can't do this. If you use ADE XL and do the sweep in ADE XL (rather than sweeping within the DC analysis), you can do right-mouse over an output for the point in the ADE XL output table and choose which to annotate. If you do a DC sweep, it doesn't save the operating point info anyway other than (optionally) for the first point.

    Regards,

    Andrew.

    thanks Andrew, yup, I was playing with ADE L (and output ocean script). I'll try ADE XL when applicable. we noticed that somehow ADE XL runs multi-corner sims much slower than ADE L running multiple times. that's why we stuck with ADE L mostly.

    Hi David,

    Well, doing a dc sweep (within ADE L or XL) will be faster than doing a parametric sweep in ADE L or a sweep of a variable in ADE XL, because it's done directly within the simulator. Using ADE Explorer or Assembler introduces some acceleration to group points to simulate sweeps more efficiently (for small simulations) which would address some of the sims quicker though (it still won't be as fast as doing a DC sweep within ADE Explorer/Assembler though, for the same reason).

    ADE L doesn't provide a multi-corner simulation capability anyway, so not sure what you're comparing against here. By the way, ADE L is in "sunset" mode and you should be planning to migrate towards the newer (since IC617) ADE Explorer and ADE Assembler tools.

    Kind Regards,

    Andrew.

    Got it, Andrew, we'll likely move onto ADE XL again and will report if still seeing problems in more specific description.

    thanks as always,

    David
