Is there a quick way to extract results from runSimulation? (like <1sec)

Alex Liao

Hi,

My runSimulation File is like this:

spectre -env artist5.1.0 +escchars  -format sst2 -raw ../psf +lqtimeout 900 -maxw 5 -maxn 5 inputTest.scs (Results are in psf/.)

I tried to use ocean script to read results. It is good if  the ocean command are only manually called few times. The call can lead to huge delays if it is called in an iterative manner in a program. (by the way I ran multiply programs at the same time and it keep taking time complaining CDS.log.* locks thing)

I have listed out few time consuming operations in the ocean command and attached the logs from running " ocean < xxx.ocn " as well as the main contents in xxx.ocn file.

I know there are different format for output to /psf, like: nutbin, nutascii, wsfbin, wsfascii, psfbin, psfascii, psfbinf, psfxl, awb, sst2, fsdb, wdf, uwi, and tr0ascii. Is there one that is easy to read results from.

Is there a -fast- way to extract /psf data to a .txt file? (For example: LNA gain in my example; the results are in ../psf/resultsSpectre.txt)

Maybe one suggested method you know  is working compatible-ly with one of the listed "-format" ! Thanks!!!!

xxx.ocn:

 ;updated on the local account to make it universal by Alex.

 openResults("../../simulation/LNA_test_tb/spectre/schematic/psf/")

p=outfile("../../simulation/LNA_test_tb/spectre/schematic/psf/resultsSpectre.txt" "w")

 fprintf(p, "Hello World!\n" )

 fprintf(p, "Hello World!\n" )

 ;selectResult('sp_noise)

 ;selectResult('sp)

fprintf(p, "Gain:\n" )

Gain=value(db(sp(2 1 ?result "sp")) 4.6e9)

fprintf(p, "End Write!\n" )

close(p)

exit

Time Consuming in order  most -> least

1st: between ocean> Loading oasis.cxt  Loading analog.cxt [ 2-3 sec]

2nd: checking CDS.log [if multiple iterative programs are executed simultaneously [usually < 1s, but can be crazily long, if even CDS.9 is being locked and run out the index of CDS.log.*, say 10 is the limit]

3rd: quit ocean mode [the exit command in the xxx.ocn]

4th: first loading ocean command:  awd.exe

Ocean command running Log:
