    Contol unit design for 32bit -ALU

    i am kinda lost in designing control unit for my 32bit ALU .. All i have is 4 modules namely addition,multiplier,logic and shifting. So i need to design a control unit for all these modules so that i can choose any module i want.. but now i came to know i cannot use condition statements to...

    how can we enable and disable the modules in verilog?

    hey guys help me out here...i need u to give me some examples to make a module enabled or disabled whenever we need in verilog HDL....

    how can i call a module from case or if else statement?

    i could not get the correct result when i run the program...my aim is when en1 is 1 and module should work and when en2=1 or module should work and so on...

    how can i call a module from case or if else statement?

    here is the test bench module arith_test; reg A,B; reg [1:0] S; wire out; arithmetic aaa1(A,B,S,out); initial begin A=0; B=1; S=2'b00; #100 A=0; B=1; S=2'b01; #100 A=0; B=1; S=2'b10; #100 A=0; B=1; S=2'b11; end endmodule

    how can i call a module from case or if else statement?

    Thanks syedshan...can you explain me with some example? i tried this program and it is showing wrong results... module arithmetic(A,B,S,out); input A,B; input [1:0] S; output out; wire en1,en2,en3,en4; assign en1=(~S[0])&(~S[1]); assign en2=(S[0])&(~S[1]); assign en3=(~S[0])&(S[1]); assign...

    32 bit barrel shifter verilog code

    Thanks Gaurav ! that really helped ! I just need a verilog simulation.. i need efficient shifting (right and left) for 32 bits .. Can you give me the code for that ? using binary search ?? We are basically designing high performance 32 bit ALU .. done with multiplier,adder and logic modules...
