假设我们用verilog写一个双控开关: verilog">//顶层文件名为top,因此等会include的头文件为Vtop//若顶层文件名为example,则include的头文件名为Vexamplemoduletop(inputclk,inputrst,inputa,inputb,outputf);assignf=a^b;endmodule 仿真过程用c++来描述,文件如下: //与verilator无关的一些头文件#include<stdio.h>...

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_...
Thanks for making a relatively complete DPI test. Please move it into test_regress. Then take this good example and shrink it to include only what is critical; as is it is now I think it'll be too confusing for people to figure out. Also heavily comment. ...
The Verilator command line uses nothing particularly fancy:-cc --build --exe --trace --trace-fst An empty name is legal according to an emitted comment in the model header: /// If name is "", then makes a wrapper with a /// single model invisible with respect to DPI scope names....

Fix DPI import of null C-string#5179 Closed Wilson, I think my original assertion is correct and your modified assertion is off by one cycle. The invisible delta delays in gtkwave are sneaky. Here's a timing diagram with delta delays exaggerated to make it easier to view. ...
