Recently, I mainly research the achievement of digital standard cell library. For the given library cell layout, I'm planning to extrate the LEF file for floorplan and placement. But I don't know how to abstract the physical informaltion file. I learn there are two ways.
(1) At the CIW of Virtuoso, "File > Export > LEF", is this true way to get LEF for floorplan and placement?
(2) Use softeware " Abstrate Editor", but this operation is complex, could anyone help me?
I don't know which way is true? If the second way is true , I hope I can get some guide about how to operate.
