Error while extracting layout.

archive

Dear all,

I get an error when I am trying to extract a layout using Diva. The following is the error.

"Errors exist in the rules file "/sw/cadence/libraries/HCMOS8D//DK_hcmos8d_4.0/Opus/DK_hcmos8d/divaEXT.rul".

Could you please throw some light on where the problem could be. I am using HCMOS8D (0.18u tech) as is evident above.

Thanks and Regards,
Kamesh.
