# DOC include start: FirrtlCompiler
# There are two possible cases for this step. In the first case, SFC
# compiles Chisel to CHIRRTL, and MFC compiles CHIRRTL to Verilog. Otherwise,
# when custom FIRRTL transforms are included or if a Fixed type is used within
# the dut, SFC compiles Chisel to LowFIRRTL and MFC compiles it to Verilog.
# when custom FIRRTL transforms are included
# SFC compiles Chisel to LowFIRRTL and MFC compiles it to Verilog.
# Users can indicate to the Makefile of custom FIRRTL transforms by setting the
# "ENABLE_CUSTOM_FIRRTL_PASS" variable.
#
# hack: lower to low firrtl if Fixed types are found
# hack: when using dontTouch, io.cpu annotations are not removed by SFC,
# hence we remove them manually by using jq before passing them to firtool
