CFU-Playground

一共支持3种运行环境，分别是Arty A7, Renode和Verilator simulation

• To run on Arty

  $ make prog //builds and program gateware
  $ make prog TARGET=digilent_arty USE_SYMBIFLOW=1
  $ make load //builds and load C program (BIOS)
  

  make load成功后会进入串口界面，如下图所示： 也可以用其他串口工具(比如Putty)，默认波特率是1843200(在proj.mk中定义)

• To run on renode

  $ make renode
  

• To run in simulation

  $ make load PLATFORM=sim
