Way to use SKILL script to save WAVEFORM into a file in ADE-XL Run

Dear rfstuff,

>I have to run a multi-corner ADE-XL simulation and I have to save the waveforms into separate files.

> Later I can use these files in pwl source for other test-benches. This way I can fasten the simulation for later cases.

I am sure this can be accomplished multiple ways...two or three methods that I use follow.

1. Write a short ocean script to traverse the ADE-XL directory structure, open each set of results, use getData() to access the waveforms of interest, and write the waveforms you want to text files using either an fprintf() statement or OcnPrint(). I have attached an ocean script that might serve as a template.

2. Alternatively, you can plot all the corner results on one graph in ViVa, select them all and, using your right mouse button, "Send to...Export..." or "Send to...Table" . The former might be best if the number of time points in the waveform is large.

I am sure many other very skilled designers have other methods of accomplishing your goal.

; Main routine

simulator('spectre)

base_results=strcat("<path_to_your_results>/results/data/Interactive.0/")
sub_dir = strcat("<ADE-XL test name>")

TSTOP = 30e-09

init_val = 1
final_val = <number_of_corners>

sim_case = init_val
while( sim_case < (final_val + 1)

printf("sim_case = %d\n" sim_case)
sprintf(sim_case_val "%d" sim_case)

; Define unique output file for each ADE-XL set of simulation results

fname = strcat("<your output file name>" "_" sim_case_val ".csv")
fp_params = outfile( fname "w")

results=strcat( base_results sim_case_val sub_dir "psf")
printf("Results directory\n%s\n" results)

openResults( results )
selectResult( 'tran)
;ocnPrint( ?output "outputs.txt" outputs())

; Load waveform "vc"

vc = getData("/vc" ?results "tran" ?resultsDir results)

tstart = 0
tstop = TSTOP
sim_time = tstart

delta_t = (tstop - tstart)/1000.0

while( sim_time < (tstop + 0.10*delta_t)

fprintf(fp_params "Time,vc\n")
fprintf(fp_params "%1.8e,%1.8e\n" sim_time value( vc sim_time))

sim_time = sim_time + delta_t

) ; end while loop

close(fp_params)

sim_case = sim_case + 1

) ; end sim_case loop


exit()

One way could be to use the code in this thread. Load this file in your .cdsinit using:

load("abDumpWaveform.il")

and then add an output expression in ADE XL such as this:

abDumpWaveform(VT("/outdiff") strcat(openResults() "/dump.txt")) && 1

The VT() would be whatever signal you wish to save, and the "dump.txt" is the file name you want (it will save this at the same level as the netlist and psf dir for each simulation point in ADE). The && 1 part is just to ensure the expression returns a number to prevent any errors.

If you then run a simulation and go over the point you're interested in and do Right Mouse->Open Terminal you'll then see there's a dump.txt file in that directory.

Hope that helps?

Andrew.

Thanks a lot Shawn and  Andrew.

Dear Andrew,

We can save N multiple waveforms in a single file.
abDumpWaveforms("data.out" VT("/c") VT("/z") VT("/a") ?format "%-10g" ?separator ",").

But, is there an efficient way we can have the single file to be used in a testbench for N vsources ?

See my response in your other post (I would have answered this sooner but have been away this week).
