How to connect output to input in Verilog?

I want to connect B’s output to C’s input. module my_moduleA (inA, outA) input inA; output reg outA; //If you want to assign something to out inside an always block, it has to be output reg, otherwise you will have to use assign out from an always block.

When to use continuous assignment statement in Verilog?

How to instantiate module in Verilog Stack Overflow?

//Put your logic here //Instantiation of module A my_moduleA instance ( //Here is the connection made between module A and B .inA (inB), .outA (outB)); endmodule This is how the connections are made, if you want to make those connections on internal signals, then you can use wire type

Can a Reg be declared as a variable in Verilog?

Let’s clear up the latter topic right now. Anything on the Left-Hand-Side (LHS) or a procedural assignment (always, initial, task, function) must be declared as a variable type (typically a reg). Everything else in the language is a net (typically a wire).
