How to add variable to dynamic parameter file

Spectre has recently been enhanced to support variables within a paramset - see How to use design variable to control transient dynamic parameter set (this was added in SPECTRE21.1 ISR9, so pretty recently). You will need to update your spectre version to allow this.

Hi Andrew, thansk for your feedback. What is the best way to check spectre or mmsim version?

BR

From the command line, "spectre -W" will tell you the sub-version. It also appears at the top of the spectre log file.

Andrew

perfect, thanks for your clear answer!

Hi Andrew,

I have updated the spectre(mmsim) version to 21.10.460 ISR 10. 

In tran sim page

the file content is

the variable temp_perf has been defined in test/design_variables

Then the sim log tells me

obviously, the variable is still not be recognized. 

Could you do me a favor to check up?

Thanks

It does not work with the param_file approach. The UI also hasn't quite caught up to do this via the paramset option either, so there are two ways of handling this right now.

The first is to create a file such as this:

time temp
0 25
36m -20
54m 25
72m 70
90m 25
115m temp_perf

and then (don't turn on the dynamic parameters checkbox) on the Misc tab of the transient options form, in the additionalParams field, enter:

paramsetfile="/path/to/paramsetfile.txt"

The second approach would be to create a file (with a .scs suffix, e.g. paramset.scs):

tempChange paramset {
 time temp
 0 25
 36m -20
 54m 25
 72m 70
 90m 25
 115m temp_perf
}

and then include this via Setup->Simulation Files->Definition Files or Setup->Model Libraries. Then in the same additionalParams field mentioned above, enter:

paramset=tempChange

Either should work.

Hi Andrew,

I tried your 2nd solution, it works well. Perfect!

Thanks for a lot for your suggestion!
