Run plan for running a single test with different variables each time

Hello,

I have a design that has several switches that guide the signal path in a way or another. I'm required to test the linearity using HB for the different cases where some switches are on or off for a range of input power values.

The switches enabling is controlled in my test via design variables (that are also global variables). Initially, I had several tests running HB and their only difference among themselves being that some switches were enabled and others not. However, that requires too many tests to be taking care of, so I thought using the run plan would help.

- variables that need to be set 1/0 depending on the case -

Unfortunately, I see that every time I create a run from an active setup, the design variables are grayed out. If I update them to consider another case in my active setup and create a new run out of it, then the previous run I created also gets updated, which defeats the purpose.

I thought maybe overriding the global variables in the run plan would work, but unfortunately the 2nd run global variable settings overrides the first one, defeating the purpose again.

I read in this link...

https://support.cadence.com/apex/techpubDocViewerPage?xmlName=assembler.xml&title=Virtuoso+ADE+Assembler+User+Guide+--+Working+with+Run+Plan+-+Working+with+Run+Plan&hash=pgfId-1024871&c_version=ICADVM20.1&path=assembler%2FassemblerICADVM20.1%2FasmRunPlan.html#pgfId-1024871

that a run cannot have its own copy of a test. Perhaps that explains why my attempts failed.

My questions are then:

Is there a way of running my test without having to create copies of it whose only differences will be setting some vars to 0 or 1?

If the run plan feature of assembler is incapable of this, what would be another approach?

Looking forward to your answer,

Best,

Ernesto

I'm using ICADVM18.1-64b, just FYI.

Hi Ernesto,

We added the ability to view the design variables in the run plan, but you can't set them - partly this was because there was concern about making setting up the run plan really complicated if we allowed that freedom. It's on the list to consider in the future, but it needs a simple enough use model to do this.

However, you said you also have global variables for these settings - I don't see why you can't change those? Changing the global variable in one run in a run plan does not affect the other runs in the plan, so I'm not quite sure why that wouldn't work for you. Can you show a screen shot of the setup? It might be best to do this via customer support so we can explore your setup directly if you can't share it here.

Andrew.

Thanks for your reply. I'm the same person who asked this question (my e-mail became invalid as my company was absorbed by another one). I managed to sort it out.
I have another question about the run plan here:

I'd really appreciate it if you could reply.
