It uses the hello_vpi.vpi module that is compiled from * the hello_vpi.c program also in this directory. See the * hello_vpi.c for instructions on how to compile it. * * Compile this program with the command: * * iverilog -ohello_vpi hello_vpi.vl * * After churning for a little while, the program will create the output * file "hello" which is compiled, linked and ready to run. Run this * program like so: * * vvp -M. -mhello_vpi hello_vpi * * and the program will print the message to its output. Easy! For * more on how to make the iverilog command work, see the iverilog * manual page. */ module main(); initial begin $my_hello; $finish ; end endmodule
