Difference between wire reg and logic
WebMar 1, 2024 · What is the fundamental difference between these types? (A) They are the same because they can both take on 0, 1, X, or Z. (B) A wire is a net data type, meaning that it must be driven at all times. A reg is a variable data type, meaning that it will hold its value after it is assigned. (C) A wire can only take on values of 0 and 1 while a reg ... WebMay 6, 2024 · Logic data type doesn’t permit multiple driver. It has a last assignment wins behavior in case of multiple assignment (which implies it has no hardware equivalence). Reg/Wire data type give X if multiple driver try to drive them with different value. Logic data type simply assign the last assignment value.

WebThe next difference between reg/wire and logic is that logic can be both driven by assign block, output of a port and inside a procedural block like this. logic a; assign a = b ^ c; // wire style always (c or d) a = c + d; // reg style MyModule module(.out(a), .in(xyz)); // wire style ... Simple difference between reg and wire is, the reg is ... WebOct 17, 2012 · var logic A; And wire A; // is a shortcut for wire logic A; The benefit of all this is that you can use typedefs and apply user defined types to add structures and multidimensional arrays to wires. You are also allowed to make a single continuous assignment to a variable of any datatype, so any distinction between logic and reg is …

WebVerilog data-type reg can be used to model hardware registers since it can hold values between assignments. Note that a reg need not always represent a flip-flop because it can also be used to represent combinational logic. In the image shown on the left, we have a flip-flop that can store 1 bit and the flip-flop on the right can store 4-bits.
