module tb();
reg [7:0] a = 1;
reg [7:0] b;
initial begin
AddTask(a, b);
$display("%d", b);
end

end

The above code is compiled and simulated correctly; But I want to cut the task "AddTask" from the module "tb.v" and place it in a separate module "AddModule.v"(that is in a separate file) for clear coding. When I do this, modelsim can compile it but can't simulate it and give the error:
" Unresolved reference to 'AddTask' ". Although I include AddModule.v, it can't recognize AddTask. Can you help me please, what's the wrong ?
module tb;
reg [7:0] a = 1;
reg [7:0] b;
`include "AddModule.v"
initial begin
AddTask(a, b);
$display("%d", b);
end
endmodule
AddTask in a separate file:
module AddModule;
task AddTask;
input [7:0] a;
output reg[7:0] b;
begin
b = a + 1;
end
endtask
endmodule
Decryptdefined? Where do you reference it? This is not clear from your example code. – damage Mar 15 at 8:21AddTask, I'll edit this – saman samani Mar 15 at 8:27
