Spectre wildcards in saving device currents

[Philipp Ritter]

Dear all,

I'm using MMSIM Version 11.1.0.509.isr14 32bit for circuit simulation of
a large design. I need to extract a lot of currents from iterated
instances inside the hierarchy. I cannot simply save all currents of the
design because the results files become way too large. For voltages
there is the possibility to use wildcards, e.g. such as

save Toplevel.Sublevel\<*\>.netname

used for saving nets "netname".

The same didn't work also for currents, e.g.

save Toplevel.Sublevel\<*\>.Subsublevel.Instance:currents

didn't bring anything in the results browser of device "Instance" in the
hierarchy tree.

However, for a single Sublevel, e.g. Sublevel<123>, it worked:

save Toplevel.Sublevel\<123\>.Subsublevel.Instance:currents

Is this a known bug or do I need to take a different approach?

Thanks!

Philipp

You'll need to ensure you pass sigtype=... (see spectre -h save for more
details).
