In my ocean script, i am using the ADEXL ocnxlOutputSummary command to output the results of my simulation into a file
I use the poport command to redirect my output. The problem is that i cannot format the output into a comma separated file, nor am i able to filter only the output expressions i need into the file. This file has a log of the entire session
Is there a way to
1) save just the result of the simulations : output expressions , parameters and design variables associated with the test i need using a regular expression filter into a file
2) How can i get only ocnxlOutputSummary(?exprSummary t ?specSummary t ?detailed t ?wave nil) to output to a file?
I wish the ocnxlOutputSummary command had a ?file "filename" field available.
Any help would be greatly appreciated, i cannot believe that a tool as powerful as ADEXL does not have a ocean command for writing the output to a csv file along with all the parameters. I am certain i am overlooking something.....
In reply to rkic:
ocnxlOutputSummary() has a keyword argument ?fileName in IC615 ISR8 (126.96.36.1990.8) (not in IC614 or earlier IC615 hotfix versions though). As a workaround you could use this (from the OCEAN class):
Currently the ocnxlOutputSummary does not support writing the summaryinformation to a file. If you want to do this, the following wrapper aroundocnxlOutputSummary may be used. This takes the same arguments asocnxlOutputSummary, but adds an extra ?output argument to allow a file outputhandle to be specified:procedure(TrOcnxlOutputSummary(@key (output poport) @rest args) let(((poport output)) apply(’ocnxlOutputSummary args) ))An example of using this:prt=outfile("summaryReport.txt")TrOcnxlOutputSummary(?output prt ?exprSummary t ?detailed nil)close(prt)

There's also a function axlExportOutputView() which outputs CSV or HTML in IC615 ISR8 (I think we plan to add an ocnxl equivalent, but that hasn't happened yet; CCR 942599 is for that). Unfortunately you can't use this from OCEAN because the function currently assumes there's a GUI ready and initialized (so axlExportOutputView(ocnxlGetSession() "./output.csv" "Detail") won't work). That's what the CCR is for...
So if you want this, you can file a service request and request the same thing - and a duplicate can be filed. There is the axlReadResDB function which would allow you to read the results database and then iterate over it however you like and generate your own output, but probably the above is closer.
In reply to Andrew Beckett:
Thanks so much Andrew! The procedure should solve my problem for now.
I have a ocean script which looks like this:
ocnxlLoadSetupState( "ron" 'overwrite ?tests t ?vars t ?parameters t ?currentMode t
?runOptions t ?specs t ?corners nil ?modelGroups t
?extensions t ?relxanalysis nil )
set and enable corners.
ocnxlRun( ?mode 'sweepsAndCorners ?nominalCornerEnabled nil ?allCornersEnabled t ?allSweepsEnabled t)
ocnxlOutputSummary(?exprSummary t ?specSummary t ?detailed t ?wave nil ?fileName "results.txt")
There were 1536 splits which ran in netbatch (our pool of machines) with 180 jobs in parallel. The job ran for 3 days and it finished simulation of all splits. But for some reason, the last split got hung in netbatch. So the ocean script never reached ocnxlOutputSummary. I can see spectre.out has completed successfully for all splits.
How do I execute ocnxlOutputSummary now?
axlExportOutputView(ocnxlGetSession() "./output.csv" "Detail") didn't work as ocnxlGetSession() returns nil.
I tried axlReadResDB. It returns the db object. However don't know which commands to use to dump the csv file.
(PS: My 2nd attempt to run simulation all over again failed. This time one of the job was hung during netlisting. This simulation is with parasitics, so takes longer.)
I am using IC188.8.131.520.11
In reply to Tajinder:
I'm not sure how to do this off the top of my head. You can certainly open the ADE XL view and go to the history produced by the OCEAN run and do a RMB->View Results (in the history tab of the Data Assistant in ADE XL).
However, if you want to do ocnxlOutputSummary on a previous (now closed) session, I'm not sure - so please contact customer support over this.
