用的是cpt-bk分支吗？checkpoint需要使用cpt-bk分支，参考https://xiangshan-doc.readthedocs.io/zh_CN/latest/tools/simpoint/

cpt-bk 分支的编译方法是 make ISA=riscv64 XIANGSHAN=1

Look like VGA issues. Should be fixed by https://github.com/OpenXiangShan/NEMU/pull/21. Could you please have a try with the current master branch of NEMU?

1) 我们只在clock为低的时候，输出了波形：https://github.com/OpenXiangShan/difftest/blob/master/src/test/csrc/verilator/emu.cpp#L296-L305 2) Verilator输出的vcd波形就是这样的，具体原因可以问一下verilator的社区

可以用香山的nanhu分支，那个分支上默认现在会打印所有波形
