![]() I get errors from the if statements when I try to compile the code, and get the warning about implicit definitions and error of not being able to evaluate genvar of the conditional in the ifs. Where the full adder is completely functional, so there are no problems there. select output depending on values of carries most significant full adder computationįullAdder f3_h (s3,c3,p3, g3, a, b, ch) įullAdder f3_l (s3,c3,p3, g3, a, b, cl) Wire c0, c1, c2, c3 //temporary buses for cases of carriesĪssign ch = 1 //assign ch to high and cl to low Wire s0, s1, s2, s3 //temporary buses for cases of sums Wire P,G //buses for P and G outputs of fullAdder Reg ch, cl //temporary variables to define cases that previous carry is high or low ![]() Output sum //sum output of the adder, 4 bits wide Module carrySelect (sum, cout, a, b, cin) ![]() Full Adder body, define structure and internal wiring Define all inputs and outputs for single bit Fulll Adder So I am trying to design a 4-bit carry select adder in verilog, and am using the following code for the design: module fullAdder (S,Cout,P,G,A,B,Cin) ![]()
