Is there a way to eliminate undesired data from a psfxl file to save area in a maestro output?

Dear scottwatx,

Is there a way I can save out those key outputs, and delete the rest from the psfxl file, so that I can still reference the data from maestro assember without maintaining 300GB of signals which are of no use

If I understand your question correctly, yes this is possible. Open a results browser window and then open the psf directory to which you wrote the simulation data. Select the transient results and then click on the signal(s) you want to save. Using your Right mouse button, you should see an option "Export..." and "Export (see Figure 1). This will allow you to export the waveforms you select into the format you choose. In your case, it appears you want to save them as psfxl - so select that option. As shown in Figure 2, you can then save the selected signals to a new psfxl file.

Let me know if I understood your question correctly - hope so!

Shawn - thank you for your reply.  I don't think that will do what I want it to do, which is keep the data accessible from maestro, so I can see the outputs all listed by corners, the mins and maxes and which corners meet the specs.  I want to keep that but delete the 10000 other signals that I don't care about:

If you're OK with keeping the scalar results but none of the waveforms, you can do that over the history in the history tab of the data view assistant by using Right Mouse->Delete Simulation Data.

If you want to keep some of the waveforms, then one way (it's going to need a bit of scripting) would be to use the srrextract.sh utility that's in IC618 and ICADVM181. For each leaf psf directory, you could do:

srrextract.sh -database psf -dataset tran-tran -signal out1 -signal out2 -signal out3 -o psfnew

You could then move psfnew to be psf (this will only work if you only care about just one analyse's results), or replace the individual PSF XL files in the original psf directory with the files from the new directory (note the names may be tran.tran.tran* in the original and tran.tran* in the new, so you'd need to keep the original names if you do this).

Back up your data first before trying this! (or try it on something small that doesn't matter first).

Andrew -

I finally had the time and the necessity to trim my database.  I used srrextract.sh as you suggested and it worked like a champ.

Thank you,

Scott

I spoke too soon.  When I leave the file names as tran.tran.* I can't read the files from maestro, but when I change them to tran.tran.tran.* I can't even read the database from the results browser.  Is there any solution for this?

It should work if you keep the original psf directory and logFile within that psf directory, and just replace the tran.tran.* files (with the original names) with the newly created files. Essentially the file names must match what is in the logFile.

I just did this, for example:

UNIX_4> srrextract.sh -database psf -dataset tran-tran -signal outp -signal outn -signal diffOut -o psfnew
UNIX_5> ls psfnew
logFile tran.tran tran.tran.psfxl tran.tran.sig
UNIX_6> cd psf
UNIX_7> mkdir old
UNIX_8> mv tran.tran.tran* old
UNIX_9> mv ../psfnew/tran.tran tran.tran.tran
UNIX_10> mv ../psfnew/tran.tran.psfxl tran.tran.tran.psfxl
UNIX_11> mv ../psfnew/tran.tran.sig tran.tran.tran.sig

Then in both Explorer and the results browser, I can plot the signals.

Andrew.

That was my problem, I had used the new logFile instead of leaving the old one

Thanks again!
