Problems with ncsim and ams simulation

[Andreas]

Hi,
I've got a problem, when I want to start a mixed signal simulation using
ncsim. At first the simulation worked well, but now I getting this error
message:
[...]´
ncsim: *internal* (eu_set_sensitivity: analog simulator gave us a bad
analog ID).
Observed simulation time : 0 FS + 0
[...]
The problem is, that I haven't changed anything in my design and it
doesn't work anymore. I tried a lot of things, but it's still not working.

Any ideas...?

Thanks,

Andreas

Hi Andreas,
I am guessing you have an analog quantity (either a probe or a
variable) being accessed from within digital portion of your design,
which ncsim isn't able to handle yet. Are you using Verilog-AMS ?

Is it possible for you to post (at least the portion of ) your design ?
Cheers,
Prasanna

Yes, I'm using allmost everything (verilog, verilog-a, verilog-ams and
spectre) in my design.

I'm sorry, I cannot, the project is quite big and I don't know, which
part causes that problem. The simulation worked once and now the
simulator doesn't start anymore, although I'm sure, that I haven't
changed anything in my design.

Thanks for your help,

Andreas

I found a few references to this error message - but all were fixed several
releases ago. What version of ncsim are you using? (type "ncsim -version").

Regards,

Andrew.
