Error with Calibre DRC/PEX using IBM PDK

growingmind Dec 9, 2018 1:18 PM

Hello,

I am using a fairly recent IBM PDK with Calibre 2011 and Cadence IC6.1.4 - both of which are fairly old, probably before the PDK was created.

PDK says it was tested with Cadence IC6.1.7 and Calibre 2015.

I am getting an error with the DRC rules file: I attached it here and deleted the proprietary information.

Is this error because of the version of Cadence I am using and the version of Calibre ?

If I upgrade either or both - will this error go away ?

Can I be fixed with the set up I am using now ?

This posting is similar to one from 8 years ago here which had no answer:

Calibre xRC, PEX setup for 65nm IBM

Can anyone help me resolve this issue ?

Thank you

Hello,

Can you see this KB article? https://support.mentor.com/en/knowledge-base/MG243608

Upgrading to a version of Calibre newer than 2011.3 will fix the issue. Or you can convert the top-level SVRF rule file into a TVF file and the error should go away. Basically, in that version of Calibre, you can't include a TVF file from an SVRF file, which is why one solution is to convert the top-level file to TVF.

Regards,
matt

Hello,

Thank you for your response.

No, I cannot see that article, when I go to that article it says it is not found, maybe you can re post some of it if possible.

I get:

404 - Page Not Found The page you are looking for can not be found.

How do I convert the top level SVRF file into a TVF file ?

Thank you.

Add the TVF shebang to the top of the file:
#! tvf
Then wrap the SVRF code in a tvf::VERBATIM block:
tvf::VERBATIM {
your SVRF code
}
When you source the TVF file, do it outside of the verbatim block like this:
source "my TVF deck path"
So in your top-level file, it looks like line 87 would be outside of the VERBATIM as:
source "$TECHDIR/DRC/Include...."
If there is an include to an SVRF file, you need to use "include" inside the VERBATIM block, instead of "source". For example:
tvf::VERBATIM {
your SVRF code
include "./my_rul.svrf"
}

PS - I should mention that it would be better for you to update to Calibre 2015, since it was listed as tested for your PDK. That way you shouldn't have to update the rule file.

Hello,

Yes, I will be looking into updating to Calibre 2015 - it will make everything easier.

I will make the updates for DRC based on your suggestions - but based on my skills in programming, I hope it will work.

But until then, I get another error when doing PEX: I attached it here.

Do you know how I can fix this ?

Thank you.

It's difficult to debug without the files, but it seems like the error is reporting that the CMACRO definition has a "-" in the arguments list, which it doesn't allow. It might be time to file a service request to get some professional assistance! https://support.mentor.com/en/service-request/open
