Parameters Sweep in ADE-XL results in "netl err"

dressler6

I'm trying to use ADE-XL to sweep "input voltage" for a current drivability for regulator . 

I select 'From/To' in the 'Parameterize'  and then select 'Linear @Step Type' for input voltage sweep.

ADE-XL works correctly if:

  1. I don't set any Parameters
  2. Set a single value in the Parameters

ADE-XL results in "netl err" if:

  1. I set any type of specification for the parameter.
  2. The specific error in the log is: 


\o
\o *Info* Run start for Point ID (18 1) on testbench [
\o GF130BCD_PUMP_REGULATOR:zIMSI_VPASSPMP_PUMP_4STG_4PF:1 ].

How to fix it? please help me.

I recently installed a new PDK.

    Which version of Virtuoso are you using? Help->About in any window will tell you.

    I can't really see how this would have anything to do with the global variable sweep - it sounds like a problem with the PDK. So I can't explain why it would work with a single value for the global variable, unless it's something to do with some code not being loaded in the background virtuoso process when you're doing sweeps (when you run a single simulation in ADE XL, the "Optimize Single Point Run" setting in the Options->Job Setup means that the netlisting for a single point is done in the foreground. Can you also try disabling all your sweeps, making sure it runs, and then turning off "Optmize Single Point Run" on Options->Job Setup and trying to run again to see if it fails then too?

    Regards,

    Andrew.

    Thank you, Andrew.

    Version of Virtuoso is "IC6.1.6-64b.500.14".

    I did not select "Optmize Single Point Run", and I disabled all sweeps. Then it failed.

    To solve this, what should I do?

    The best avenue would be to talk to customer support, because trying to diagnose this here is going to be quite hard. We can try though. Perhaps you can set up a single simulation with Optimize Single Point Simulation turned off, and then when it fails immediately look at the Job log (right mouse button over the little terminal icon that will appear in the Run Summary Assistant; you might want to copy that file elsewhere). This might give a clue about something from the PDK failing to load which might be causing the issue. You can always post that here so that I can take a look, but in general customer support would be easier as then an Application Engineer can look at this with you.

    Regards,

    Andrew.

    Andrew. Very grateful for your help.


    your advice was so valuable that I would be without anyone's help.

    I tried many different things.
    Of the things you said, there was a hint about Version.
    I changed the version and confirmed that it works.

    (IC6.1.6-64b fail-> IC6.1.7-64b  & IC6.1.8-64b run)

    I'll check out other versions.

    But I do not know why this is solved.
