ORFS Check antenna: Command terminated by signal 6

[marcopoles]

Hi,
working on import foreign tech, I'm running gcd desing and the flow stops at antenna check with following output:

Any suggestion about the problem origin?

Thanks,
Marco

Its hard to know. Is this something where a test case could be provided?

[marcopoles]

I suppose that the test case creation will include lib+lef, so I can't.
I tryed the flow on a very simple design and it works (2 FFs+2 NOR).
The tech is tsmc 40nm CMN40ULP, in case you know someone who has already worked on it.

I will proceed by trial and error to understand which std cell is causing problems.

Thanks,
Marco

You could also ignore antennas while doing bring up. The other option would be a 3-way NDA with Precision Innovations so that we could see the problem.

Following your suggestion to comment check_antennas in global_route.tcl the flow arrives to end.
We are available to a 3-way NDA. Do I have to write directly to [email protected]?
Thanks

Sure we can start a discussion from there.
