Calibre / PEX / During Calibre view creation / *Error* close: argument #1 should be an I/O port (type template = "p") - nil

sl933

When I run PEX (passes LVS) and try to create a Calibre view, it goes through "Running Back Annotation Flow", then it errors out:

Calibre View generation encountered a fatal Error.
Please consult the logfile for messages.

The only error message from the log I can see is this:

*Error* close: argument #1 should be an I/O port (type template = "p") - nil

I have been digging forums, etc. but cannot seem to find what is wrong with this PEX.

What is argument #1 and type template "p" anyways?

Thanks,

Sunwoo

PS I am using "sub-version IC6.1.8-64b.500.6 "

  • Hi Sunwoo

    The error message is saying that the input to the "close" SKILL should be a file handle. "p" refers to the input data type. In this case, it means "I/O port" type. As Calibre is a tool from Mentor Graphics, would you please get more help from Mentor's forum?

    Thanks! It turned out that parts of the PEX code we got from the foundry had inconsistent port names (i.e., some devices in the code had 'GND' ports while the other devices had 'VSS' ports).

    Cheers,
