Tool: Encounter 14.2
The design kit has 3 LEF files for the following.
- Header file (Metal & via information)
- Core cells
- Antenna Information for metals & core cells.
During place & route, I add these files in the order given above.
When I tried to create a PG library for Rail Analysis, I got the following warning.
** WARN: (VOLTUS_LGEN-3036): Duplicate macro definitions were found while processing the LEF files. This may indicate that the MergeLef program
should have been run before starting VOLTUS_LGEN.
Could you explain how to run MergeLef program ?
