; This example tests the operation of a simple posedge event. The module
; that would generate code like this would be:
;
;    module main;
;        reg a;
;
;        initial begin
;          a = 0;
;          #1 a = 1;
;        end
;
;        always @(posedge a) $display("Got a posedge.");
;
;    endmodule
;

main	.scope module, "main";

V_main.a	.var "a", 0 0;
V_main.b	.event posedge, V_main.a;

code
	%set/v V_main.a, 0, 1;
	%delay 1, 0;
	%set/v V_main.a, 1, 1;
	%end;
	.thread	code;

loop	%wait V_main.b;
	%vpi_call 0 0 "$display", "Got a posedge.";
	%jmp loop;
	.thread loop;
