Ocean XL post processing corners

Chris Smit

Hi,

 I have setup a simulation in ADE-XL with a corner defined (temp_freq_proc) that sweeps frequency, process corner and temperature. In total this results in 60 different runs (numbered temp_freq_proc0 to temp_freq_proc59). I am able to select the output and plot all 60 results at the same time into a plot.

However I would like to be able to extract a subset of the simulated corners, eg temp_freq_proc0 to temp_freq_proc20 to only show corners at one particular temperature. This gives a better insight in the data.

 Since I have allready done all these (long) simulations I don't want to redo them temperature for temperature...or frequeny for frequency

If I for example use the function ocnxlGetCorners() it only returns nil in stead of a list of all defined corners. How do I select a specific result for a specific corner?

BTW: I use IC6.1.3

Thanks for your feedback.

    Hi Chris,

    Sorry about the delayed response to your post.

    If you want to plot this interactively, then you can select the little "wave" icons for all the different corners you want to plot (by all means sort them how you want first to make it easier to select multiple things) and then use RMB->Plot to plot just those waveforms.

    If you're looking to do this from SKILL/OCEAN, then it's a littler tricker because the public API isn't there yet. By all means contact me directly via email, and I'll open a service request (since you're in my region - albeit I'm in the US this week) and we can follow it up there - there are some workarounds (which I don't want to publish here as they involve private functions) and some enhancements already filed to improve access to detailed result data in an easer way from OCEAN.

    Regards,

    Andrew.

     Hi Andrew,

     No problem, in the meantime I worked out a solution I can work with for the moment. Interactive plotting is not a real option here since I want to plot several waveforms on one plot using strip mode. One strip for each signal containing all corners for that particular signal. If you plot interactive you need to rearrange your plots often.

    My solution is somewhat manual. I created a list of corners (manual inspection) and used a for loop to directly read out the data in the results directory. However it would be nicer to have obtained a list of corners that could have been selected using a parameter. If I need to update my scripts I will contact you.

    Here's a small example of my code:

    cornergroup = list( '(1 2 3 4) '(5 8 10) '(45 56 59) )
    foreach(cornerlist cornergroup
    foreach(corner cornerlist
    sprintf(dir "/home/user/results/data/Interactive.1/%d/lib:block" corner)
    wavef = v("some net" ?result 'tran ?resultsDir dir) 
     plot(wavef ?strip x)
    )
    )

    Thanks for your feedback

    Chris.
