Is this even valid ? I mean passing an event as an argument to a
function that expects a logic input ?
Btw, your code does not compile, not even with ModelSim.
I modified it as follows:
// Module.
module my_module;
event my_event;
reg x;
// Function.
function my_function;
input my_args;
begin
$display("foo");
end
endfunction
// Call function with event.
initial
x=my_function(my_event);
endmodule
And even this does not compile (neither with iverilog 0.9.1 nor with ModelSim).
Here's the ModelSim compile error:
** Error: t.v(16): (vlog-2110) Illegal reference to event "my_event".
And this is the iverilog 0.9.1 compile error:
(null):0: vvp-tgt error: unhandled expr. type: 17 at eval_expr.c:2865
