/*
* Here we have the canonical "Hello, World" program written in Verilog,
* with VPI. 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.
