Generate Netlist from the Command Line

At the beginning, set:

envSetVal("asimenv.startup" "projectDir" 'string "/d2/data/GFBCD013/013BCDlite/CDS/DL-000024/Rev14/OA/1P6M_9kA_1k_1p0f_SM/simulation")

Other than that, it looks fine.

Hi Andrew,

Thanks for the reply, that did the trick.

I have follow-on question. When I generate the netlist using the above method, in the netlist directory, there are two files. One is  "input.scs", the other is "netlist". Then, I use ADE to generate an ocean script and then run the simulation from ocean script. I found that there are overlaps between "input.scs" and my ocean script, regarding the model files & simulation options & results/data output, saving, etc. After I run the simulation using ocean, the overlap part of input.scs is modified to be in agreement with the ocean script, especially the model files part. Is this expected?

After the ocean simulation is finished, I had a look at the spectre.out file in psf directory. It says:

""""""""""""""""""""""""""""""""""""""""""""""

Spectre received SIGTERM.

Error found by spectre.
    ERROR (SPECTRE-25): Killed by user.
"""""""""""""""""""""""""""""""""""""""""""""""

It seems that the ocean script has killed spectre prematurely. Since I got all the results I wanted and simulation runs smoothly and I didn't try to kill spectre in my ocean script, I'm wondering if ocean is internally implemented this way?

Below is part of my ocean script.

"""""""""""""""""""""""""""""""""""""""""""""""""

analysis('tran ?stop "30u"  ?errpreset "conservative"  )
desVar(   "vinamp" 1    )
envOption(
        'analysisOrder  list("tran")
)
saveOption( ?simOutputFormat "psf" )
saveOption( 'pwr "total" )
saveOption( 'save "selected" )
save( 'v "/vdc" "/rfinp" "/rfinn" )
save( 'i "/I7/rfinp" "/I7/rfinn" "/R0/PLUS")
temp( 27 )
run()

outVol = VT("/vdc")
plot(outVol ?expr '("outVol") )
hardCopyOptions(?hcOutputFile "vdc_out.png")
hardCopy()

plusInVol = VT("/rfinp")
plot(plusInVol ?expr '("plusInVol") )
hardCopyOptions(?hcOutputFile "rfinp_out.png")
hardCopy()

minusInVol = VT("/rfinn")
plot(minusInVol ?expr '("minusInVol") )
hardCopyOptions(?hcOutputFile "rfinn_out.png")
hardCopy()

powP = (integ(VT("/rfinp") 2e-05 3e-05) / 1e-05)

summaryFile = outfile("summary.txt")
fprintf(summaryFile "Input %s C is %.3e \n" temp() powP)


close(summaryFile)
""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""

Thank you.

The netlister produces the "netlist" file and then both ADE and OCEAN assemble this into the input.scs file by adding the model references, options and analysis statements etc. So I'd expect to see that - your OCEAN script should indeed produce a new input.scs (that's how the simulator knows what you're asking to simulate).

The SIGTERM shouldn't happen - and I don't know why that is happening. It's certainly not expected. I suggest you contact customer support. I assume you don't have any CPU limits set (see what the UNIX "limit" command shows in the terminal you ran "ocean" from.

Regards,

Andrew.

Hi Andrew,

Thanks for your reply!

I did a limit from the command line, and here is the result:

""""""""""""""""""""""""""""""""""""""

[menghansun@a327-a15 psf]$ limit
cputime      unlimited
filesize     unlimited
datasize     unlimited
stacksize    10240 kbytes
coredumpsize 0 kbytes
memoryuse    unlimited
vmemoryuse   unlimited
descriptors  1024
memorylocked 64 kbytes
maxproc      126681
"""""""""""""""""""""""""""""""""""""""

I don't think this causes any problems.

Currently, I am running ocean script in two ways:

(1) type ocean from command line, and start an ocean session, from there,

load("myoceanscript")

(2) from the command line, ocean < myoceanscript > ocean.log &

(1) doesn't cause SIGTERM to spectre.

(2) does cause SIGTERM to spectre.

Does that mean anything to you?

Thank you very much,

Menghan Sun
