Calibre pex is not creating .pex and .pxi files.

Hi,

i am running calibre pex for post layout simulation. After extraction I want to do the post layout simulation using the spectre and not from the config view.
It requires three files one is pex netlist and two other files are with .pex and .pxi extension. The later two files are not generatng in my case.
Can please someone help me woth the issue?

Regards,
Nancy

Why would Spectre need anything else than DSPF file - named *.pex.netlist by Calibre?
DSPF file is a complete, self-contained SPICE netlist.
