Abstract generator problem

tungthanhhoang

All,

I run "Abstract generator" tool to  generate LEF file for standard cells. I pass all of the stelps, including Pin, Extract and Abstract.

But, when I export LEF file, it is created but no content inside.

Have you met the same problem and solution for that ?

  • Hi Tung Thanh,

    Is your technology information set up correctly?  For example, does the tech file have a prRules section, a prViaTypes section ?

    Which version are you using of the tools (e.g. what does "abstract -W" return, are you using icfb (CDB-based) or virtuoso (OA-based) for the design framework?)

    Have you looked at the Abstract tutorial?

      `cds_root abstract`/tools/dfII/samples/tutorials/abstract

    I hope that this information helps you to generate a LEF file.

    Regards,

    Lawrence.
