[ERROR] FastRoute cannot handle very congested design

. The design itself isn't that complicated, it's a simple RISC-V core from a 1-semester class. Perhaps the floorplan is too tight? Haven't found much through searches. Anyone else run into this?

@aryap You'll probably face that a lot. In this case you need to reduce both FP_CORE_UTIL and PL_TARGET_DENSITY. Check this for more.

perfect, thank you!
