Hi, i downloaded a freePDK45nm to use at synthesis and PnR.
In freePDK45nm, there are
- gscl45nm.db
- gscl45nm.lef
- gscl45nm.lib
... etc
During synthesis step, there was no problem because synthesis only need .db file.
But during PnR step, IC_Compiler need milkyway form and i dont have it.
In gscl45nm.db, there are basic cell information such as
AND2X1, AOI22X1 ...
And I think the milkyway lib should be look like this
But i dont know how to gen milkyway lib...
