; This example slightly extends the hello.vvp example by adding the
; set and display of a reg variable. The Verilog source that would
; make this might be:
;
;    module main;
;        reg [3:0] value1;
;        initial begin
;           value1 = 1;
;           $display("value = %b", value1);
;        end
;    endmodule
;
; Notice that the var "value1" is placed into the "main" scope simply
; by having main current when the .var statement is compiled. And also
; notice that the Vmain.value1 label is automatically converted to a
; vpiHandle by the compiler when the %vpi_call statement is compiled.

Smain    .scope module, "main";

Vmain.value1	.var "value1", 3 0;

T00	%movi 8, 1, 4; Load a 4 bit value (1) into location 8.
	%set/v Vmain.value1, 8, 4;

	%vpi_call 0 0 "$display", "value = %b", Vmain.value1;

	%end;

	.thread T00;
