rocket-chip

# 编译verilog (mill, jvm, firtool)
make verilog
# 编译Testharness并运行riscv-tests (mill, jvm, firtool, verilator, riscv-isa-sim, riscv-gnu-toolchain, riscv-tests)
mill "runnable-riscv-test[freechips.rocketchip.system.TestHarness,freechips.rocketchip.system.DefaultConfig,_,_].run"
# mill生成idea依赖
mill -i mill.idea.GenIdea/idea

Errors

  • firtool新版工具不支持-dedup和-disable-infer-rw这两个选项，需要去掉或控制firtool版本，issue中提到用nix做环境版本控制

riscv-tests

Errors

  • 遇到stdint.h等标准库没find到，是riscv-gnu-toolchain的构建出错未完全完成，查看riscv64-unknown-elf文件夹中是否有include文件夹

riscv-isa-sim

cd ./riscv-isa-sim
../configure --prefix=$RISCV 
make -j

# more oprions example:
../configure --with-boost=no --with-boost-asio=no --with-boost-regex=no --with-priv=MSU --with-isa=rv64gcv --with-varch=vlen:128,elen:64

# run debug
spike -d --isa=rv64gc --log-commit xxxx.elf

# python prerequisites

Errors

  • 不能 make -j8，多核情况下会报错，但其他并行编译会打印一些正确的信息把错误覆盖掉
  • configure: error: source directory already configured; run "make distclean" there first
# 删除gcc的安装目录
rm -rf $RISCV 
# 删除build文件夹
rm -rf build 
# 查看gcc、newlib、等仓库的改变情况，使用git
git status
# 使用make清除命令
make distclean
  • TODO: gdb的构建会报错: configure: error: GMP is missing or unusable
