Knowing associated TECH-FILE location

RFStuff

 Dear All,

I have installed a main stream PDK in my Cadence enviornment.

While creating a new library, I associated the techfile corresponding to this  PDK.

Is there any way to know the location of the tech file. 

The document of the PDK days that the tech file is obtained by compiling a  xxx.asc file.

 Is there any way I can know which .asc file the tech file is compiled from ?

Kind Regards,

Parents

  • Generally when you create a library, you don't compile in the tech file, but attach or reference the technology library (which has the tech file compiled already to produce the tech.db database).

    Attaching just means that your library uses the other library for its technology data. 

    Referencing means that your library has its own technology database which incrementally tops up the technology database from the referenced library. This allows extensions of layers, constraint groups etc in your own library. A facility known as ITDB (Incremental Technology Database).

    When you compile a technology database from an ASCII technology file, it doesn't retain the path that was used to compile it.

    Regards,

    Andrew.
