pass ncsim commands through irun

Hi all,

I'm trying to pass some extra commands to the ncsim console via irun commandline. Is this possible?

A typical use case is to disable assertions. In the console we can simply write "assertion -off -all" and disable all assertions. I would like to be able to do that through the command line.

Thanks a lot,

Put the Tcl commands in a file, and then run "irun -input commands.tcl".

Hi, yes this is certainly an option, but then I need to maintain the file name, location and what not.

Any alternatives?

Ah, sorry. Didn't realise you wanted to give the tcl command directly on the command line. You can use -input but start the next argument with @. So for example:

irun -input "@assertion -off -all"

You can give multiple statements, either by separating the commands with semi-colon or by giving multiple -input commands. For more details see this article (or search in INCISIVEinstDir/tools/bin/cdnshelp for "-input").

Regards,

Andrew.

Hello Andrew, thanks a lot for the input. Indeed it works... but unfortunately it causes an issue in the connect phases of one of the uvm agents. I haven't investigated yet since the agent is an external IP and is difficult for us to modify it, so there's a discussion with the IP vendor as well.

In the meantime, do you think I can inject the tcl command only after a certain phase of the simulation?

If there is, I don't know how to do this (without spending some time hunting - maybe there is). Probably more of a Functional Verification question than mixed-signal. I suggest you contact customer support.

Andrew.
