This a demo for llvm build and sim with verilator.
jtag
This is a demo of jtag simulation by openocd running on verilator.

tips
- jtag的reset引脚要设置正确 jtag_trst_n 低电平复位
- 仿真的时候jtag的tclk不能太快,要低于soc的clk
- SweRV启动/复位后程序从
reset_vec
(0x80000000)开始,遇到错误(code=0),就会跳到mtvec(中断向量表)指示的地址 - 物理仿真的时候 adapter speed 不能太快
- data段放到0x200太小,GDB调试RISCV至少要4K的程序空间?
- soc的ram和rom直接接到了lsu和ifu,和DCCM/ICCM无关
- program.hex 用于 $readmemh 必须以空行结束
Todo
- gdb怎么复位soc
- gdb没有把程序加载到mem,ifu还是用老代码
- mem分bank后,怎么加载,用于仿真=>for循环分别加载
- Quasar升级scala版本发现openocd运行不正常
