My answer is in two parts:

1) From the HDL, you can only get the plusargs, using the predefined
system task $scan$plusargs.  This returns true or false depending on
whether the specifed plusarg is on the command line.  For example:


yourhost> verilog -axs +plusarg1value +plusarg2ref file.v

And in your description you put

reg r;
r = $scan$plusargs("plusarg1"); //r will be 1
r = $scan$plusargs("plusarg3"); //r will be 0

2) Using the PLI, you can also access the plusargs using the function
mc_scan_plusargs().  This will give the remainder of the argument.
Using the same command line as above:

char *arg = mc_scan_plusargs("plusarg1"); 

will set arg to "value."

There is currently no way to get all the arguments.  In the future
there may be hooks in the PLI to get argc and argv, but not currently.


Enjoy,
