VexRiscv

• Modify scala sources in VexRiscv/src/main/scala/vexriscv/demo:
  • Murax.scala
  • MuraxUtiles.scala
• Modify and build the program in VexRiscvSocSoftware:
  • libs/axis.h
  • projects/murax/demo/src
• Build Murax.scala from VexRiscv, in order to generate VHDL source:

sbt "run-main vexriscv.demo.Murax"
# or
sbt "run-main vexriscv.demo.MuraxWithRamInit"

• Copy generated VHDL to from VexRiscv/Murax.vhd to vhdl/srcs.
• Profit.
