What are the tools for parasitics extraction? I know Magic does it but couldn't find an alternative...
m
OpenROAD for lef/def designs

@Matt Liberty Are you referring to OpenRCX? My understanding is that it's mostly for digital designs and not for analog ones.
m
hence my comment about lef/def which is used for digital designs
I don't know of an OSS analog extractor aside from magic

Oh, LEF is also used in analog for some PnR tools, but based on what you said, I wouldn't expect the support from OpenRCX for analog will be good...
m
If you have LEF you can use openrcx/OR
however that is not a usual use case unless you are talking about integrating an analog block into a p&r design
z
Yes I am trying to integrate PnR for my analog design flow
m
when you design the analog portion you'll need to do that seperately. Once you generate the LEF you are only verify what is outside the LEF
z
"Once you generate the LEF you are only verify what is outside the LEF" What do you mean by this?
m
The lef is a black box model. All the internals are abstracted away.
