Results from PSF files are out of order

SC20250506376

Hi there,

I am trying to extract data from PSF files using Skill in either Ocean or Virtuoso.

I have found the central psf directory of a multi-parameter Maestro simulation and use:

openResults(psfPath)

After some calculations, the results can be sent to a CSV file using:

awvSaveToCSV(wave "/path/to/file.csv")

However, I find that the column order of the data is wrong. I suspect that the column order is the order in which the simulations can complete - which isn't necessarily the same as the order they are started in.

For example, the second column is associated with the fifth simulation.

I could unscramble the columns if I had some reliable information on which column is associated with which simulation number.

Can anyone make any suggestions as to how I obtain this information?

Thanks for any help with this.

Simon

    I've done a bit more searching - there's this:

    How to get corners name from ADE Assembler / XL simulation database using SKILL?

    (Requires Cadence Support Login)

    So this identifies the simulation "points" - and in the order I'm expecting - however it doesn't solve the problem. If one does openResults then awvSaveToCSV the columns in the data will be in random order compared to the order in the Maestro RDB file.

    There's a newer function awvSaveToVCSV - maybe that produces better header information?

    Anyway, I think the best thing to do here would be to contact customer support (use the Case menu to submit a support case after logging in). Sorry, haven't had the bandwidth to try this out and experiment.
