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,...

Fix DPI import of null C-string (verilator#5179).
*** Add error on DPI functions > 32 bits. (#1898) [Elliot Mednick] *** Fix SystemC compiles with VPI. (#1081) [Arthur Kahlich] *** Fix error on wide numbers that represent shifts, msg1991. (#1088) [Mandy Xu] *** Improve Verilation performance on internal strings. (#1896) ...
它藏身于dv/verilator/simutil_verilator/cpp/verilator_sim_ctrl.cc,里面便声明要使用RAM model中欲导出的两个DPI-C外部函数。 main函数中首先调用SetTop函数把clock和reset接到VerilatorSimCtrl内部。如下面代码所示。 void VerilatorSimCtrl::SetTop(VerilatedToplevel *top, CData *sig_clk, CData *sig_...
