DRC error with pcell generated by SKILL script

MinYoon

I've managed to program a new pcell with SKILL script.

New pcell is uploaded to icfb environment by ddGetObj,

and then I used separate script to generate pcell instance using  dbCreateParamInst.

However, when I try to run DRC, I would get

"ERROR: Failure to read input file xxxx at record offset 0." (where "xxxx" is the name of some calibre.db file.

If I flatten everything however, DRC tool will not give me this error.

Is anyone familiar with this type of error? I've seen other threads discussing about similar problem with schematic editor, but not layout editor along with DRC tool.

Thank you. 

  • I believe I've seen this before, but it's a question better asked to Mentor Graphics since Calibre is their tool.

    You can use Calibre either reading a stream (aka "GDSII") file (in which case I don't think you'd have this problem, and if you did it would definitely be a Mentor problem) or by reading the OpenAccess database. To read OA with the pcells present, you will need to setup up "Express Pcells" (search in cdnshelp for more details) but will also need to follow the steps in Mentor's Calibre documentation to tell you how to set up the express pcell plugin in Calibre.

    Kind Regards,

    Andrew
