runQRC for OA flow

diablo

Hi all, 

I have OpenAccess flow in encounter. For signoff timing, I am using signoff extraction using runQRC in SocEncounter 8.1. From the document:

The following command extracts RC parasitics using technology file qrc.tch, and cell library file library_new, and generates a reduced SPEF file qrc.spef:

runQRC -outputFileName qrc.spef -techFile qrc.tch 
   -libraryName ./library_new

 When using the above command for signoff extraction in OA flow, what is the library_new should be? I tried to list the name of OA lib of standard cells but it gives error saying incorrect library director.  Are we supposed to give library name, or point to the library path? I have tried both and it doesn't work. Any suggestions? Thanks..

  • runQRC with OA will be supported from 9.1 when it supports QRC CCL command style. The CCL command file is where the library definition, cell name etc can be specified.

     Since you are inside Encounter (DEF and cell lefs already available) any specific reasons to run on OA db?
