WebTo facilitate the process of testing the code, your FSM module should have the following ports. module edgedetector_bh ( input wire clk,input wire signal, output reg outedge ); wire slow_clk ; reg [1:0] c_state ; reg [1:0] r_state ; // Define your FSM states localparam ZERO = 'd0; localparam CHANGE = 'd1;localparam ONE = 'd2; // // See slide 19 … WebJun 1, 2024 · As the wire type is a basic point to point connection, we can use wires as either input or output types when we declare a verilog module. In contrast, we can only use the reg type for outputs in a verilog module. We primarily use the wire type to model combinational logic circuits in verilog.

WebJan 26, 2024 · Inputs are declared as reg and outputs as wire only in Verilog. In SystemVerilog, we use logic for 4-state simulation and bit for 2-state simulation. In Verilog, inputs are declared as reg because they are variables which store values during simulation. The value is stored in the inputs of type reg till it is overwritten by some other value. Webinputs are wire type by definition (and for a reason). in the module that is external to your example, the output can be a reg there and that would make sense. if you need to sample …
