Title: Calibre PEX problem Post by sear on Jul 7th, 2009, 8:05am Hello, I'm designing a chip with AMS high voltage 0.35um process. I am using calibre for verification. I have passed LVS. But when I do PEX, I got some warnings and PEX will be terminated. Here are the warnings: WARNING: PEX BACKANNOTATION is obsolete. Please remove from your ruledeck.

Anybody knows how to fix this problem? Thanks. |
Title: Re: Calibre PEX problem Post by sear on Jul 8th, 2009, 9:22am I checked the PIPO.LOG file, no error is found. Calibre PEX quit with such a message: *** Calibre finished with Error: bus error *** But what is a bus error and how to remove it? Thanks in advance for your help. |
