@jwright6323 FPIR Pass error that needs to be solved. This occurs during GenerateTopAndHarness, so the Generator itself has successfully ran:

[error] Exception in thread "main" java.lang.ClassCastException: firrtl.annotations.InstanceTarget cannot be cast to firrtl.annotations.ReferenceTarget

I'm just running the default config. Steps to replicate:

git clone [email protected]:ucb-bar/chipyard.git -b dev-floorplan-new
cd chipyard
./scripts/init-submodules-no-riscv-tools.sh
cd vlsi
make verilog
