nanoroute & fcroute

The Consultant over 13 years ago

What is the difference between the two routers?

fcroute is for flip-chip routing from the bump to the IO driver. NanoRoute is for signal routing.

fcroute is only used to make the connections to the bumps which is typically from the bump to the PAD AREAIO.
NanoRoute is used to do the logic routing which includes routing between core logic (standard cells, hard macros) and also routing from the core logic to the pad.
Hope that clarifies this.
