Title: Envelope sim time limits?
Post by wave on Dec 7^th, 2010, 4:50pm

Hi all -
I'm running Envelope Analysis, looking at Voltage vs Time.
ADE 5.10.41.500.6.134

When I run a relatively short Stop Time of 1mS, things work OK.
Waveforms plot OK; perhaps 7 baseband cycles.

When I run longer sims (10-20mS), there is NO output.
ADE, Direct Plot Form, acts as if the data wasn't saved;
yet there are huge output files: envlp.fd/dt.envlp

Since I'd like to sim slowly incrementing dynamic waveforms, this is a limitation.

Any thoughts?

thanks,
Wave 8-)

Can you start wavescan stand-alone and browse to those output files? This might tell you whether the problem is ADE or the files.

Which version of the simulator is being used? Are you using harmonic balance or shooting? How big are the files (do an ls -l on the directory and post the results).

Not sure I can immediately think of a good reason for a problem, but the above might provide enough pointers to pinpoint the problem.

Best Regards,

Andrew.
