这个SimSerial.v文件定义了一个Verilog模块SimSerial,该模块用于模拟串行通信。它提供了一个DPI-C函数serial_tick来实现串行数据的收发。此外,它还包含了一些用于模拟的寄存器和信号。在模块中,有一个always块,它会在时钟的上升沿触发。如果reset为1,模块会将所有的寄存器和信号清零。否则,模块会调用serial_tick函数,...

但是我们必须解决如何把一个初始的RAM镜像load进去,如果不考虑灵活性的话,直接指定一个镜像文件也是可行的。但如果要让testbench指定的话,就必须提供一个接口,可供C++调用,在verilator编译之后这个DPI-C的函数就变成了ibex_simple_system class下的一个函数。
