SPEF file comparison for Calibre xRC and StarRC

Hello,

I run the extraction for my project using xRC and StarRC and the extracted file is in SPEF format. Then I compare the SPEF file using myBingo tool to find pin to pin resistance. The problem is the SPEF files are different for some nets ,

Example:
in xRC the net is IP1/@2 112.31 90.31 and second net is IP1/@4 112.31 91.20

in StarRC the net is IP1/@4 112.31 90.31 and seconf net is IP1/@2 112.31 91.20

Somehow the co-ordinates or name changes for both, This causing the problem for myBingo as it can't compare the nets and it just skip it considering it to be a different net.
Any solution for that ? Any configuration through which I can write the SPEF file like StarRC ?

Given that you're comparing the results of two non-Cadence tools (one from Mentor, one from Synopsys) with a third non-Cadence tool (myBingo - not familiar with where that comes from), this doesn't seem the best place to ask this question! Presumably a Mentor forum would be better since you're asking for a way to write out the xRC output differently.
Regards,
Andrew.

No problem - I'll leave it here because if anyone encounters it in future, they might also realise that asking elsewhere is a better option for similar questions.
