Can I do a timing analysis for the complete top level design including IO with the .libs for IO and spiceNetlist of the MACRO ?
* The top level design is not having any std.cells only MACROs
I am not having .lib models for the MACRO ? are they essential for PT run ? If yes, Can I write out .libs for these MACRO from virtuoso ? (MACRO are designed full custom in virtuoso)
Can we do the timing analysis for transistor level custom block in PT after generating .lib using characterisation tool ? Is that the right way ?
or we need to go with tools like nanotime to do transistor level STA ?
