Export LEF via problem

Gangadhar Redd
 Hi ,

While I trying to export .lef file from Cadence virtuoso 6.1.5 version , I got the following error

"ERROR: (OALEFDEF-50138): VIA Via56_stack_west: Failed to open master view - Open of gpdk180/Via56_stack_west/symbolic failed - cellView for the design was not found - Ensure that the via is correctly defined in the technology database."

Can anybody please solve this problem ?

Thanks & Regards,

Gangadhar.R

  • Hello Gangadhar,

    Did you manage to export a LEF from Virtuoso meanwhile? Does the view name exist (please check with the library manager) ?

    The LEF export uses the foundry section of the technology library - is the via defined ? You could use CIW - Technology Manager - Dump to write out an ASCII text file and search for the via.

     

    Regards,
    Andreas
