How can I write the db in lower version in Design Compiler?

[ipcore1981]

Hi All,

I'm using Design compiler version 2003 and primepower version 2002. When I want to read the db files in primepower. It says the db files in newer version than primepower. How can I write the db in lower version in Design Compiler?

Thanks for your help

Prerequisite: Synopsys Liberty(.lib) format of this library (Soure of .db)
==============================================
If you already have older(than PrimePower 2002) version DC, then
dc_shell> read_lib <your lib>.lib
dc_shell> write_lib -o <your lib>.db
