Call task from another Verilog module


Call task from another Verilog module

I think the issue was by ths following , Like Serge said, always include your files in the beginning of the file, right before the module statement.
code :
`include "add.v"

module maths();
//register etc details
initial begin
    add;
end
endmodule
reg A, B, C;

task add;
begin
    A = $random;
    B = $random;
    C = A + B;
    $display("Answer: %d", C);
end
endtask

Are you allowed to have a module identifier be the same as the module type in Verilog?

I wish this helpful for you Yes, it is legal for a module instance name to match the module name in Verilog, and it is quite common to do so when you only need one instance of a module. But, you could have quickly verified that for yourself by simply compiling your file with your favorite simulator. The following is legal syntax and compiles for me:
code :
module top;
    debouncer debouncer();
endmodule

module debouncer;
endmodule

With these it helps Your task in in a module and so can only be seen in the module. What you can do is remove the module wrapper and just declare the task in a separate file.
code :
task assign_inp;
    reg a,b,c,d;
    //details
endtask

should help you out Verilog modules are not run or executed but instantiated, they represent physical blocks of hardware.
Everything is in parallel unless you have made effort to time share pieces of hardware. For example you might write an ALU core, which exists only once but use a program ROM to tell it which instruction to process every clockcycle.

seems to work fine I am getting an error - "tests is not a function name." What am I doing wrong here? Can I not call a task from always block? , You can do it as shown below,

This might help you The unfortunate truth is there is no standard for interoperability between standards. Why this is the case may be highly opinionated. But I can say that if more people bring this issue up to their vendors, the more likely it may get addressed.
