Exist any free version of Calibre DRC to use in FreePDK45nm??

Hi Guys,

I'm developing layouts circuits using FreePdk45nm and the NCSU just released DRC rules checker to Calibre..

Is there any free version of the software or any option to analyse the errors?


Thanks in advance!!

The idea of using a high-$ verification tool and a free
PDK is slightly amusing.

The lack of open source verification (DRC, extract, LVS)
tools makes the availability of multiple "free" layout and
schematic design tools almost moot, at least for real work.

Some other verification tools (like Silvaco Guardian) will
"digest" Caliber error reports, although that one will not
execute a Caliber deck. You might see what tools are
available to you (how are you doing layout now?) and
whether they include Caliber compatibility in any aspect.
Or have their own rules sets available for your FreePDK.
For that matter you might look again at what NCSU's
real preferred platform(s) are and whether there's one
that is (1) free and (2) can do DRC on a GDS-II database
(since that may be the only medium that you can exchange
layout data tool-tool, by).

I see in your profile you are associated with a university -- many of them have the tools through a higher-education program MGC offers. Might check with your electrical engineering department.

If your school doesn't, you might be able to apply through https://www.mentor.com/company/higher_ed/application/ .
