I am using the parameter keyword to define a state, i.e., RESET = 5 b00000. If I want to use $display to print out the state name instead of the binary representation, or display the state name in my ...

Sorry for Newbish question. I am trying to learn about FPGA programming. Before I spend $1K on a FPGA board: if I just want to learn Verilog, can I run it entirely in Modelsim? (I realize there are ...

I have a wire that is about 4 levels deep and I really don t want the hassle of having to propagate it up the hierarchy. Is there any way to assign the wire using some sort of referencing? I know I ...

What does the schematic looks like for the following verilog code? module mystery2(s, c, x, y, z); input x, y, z; output s, c; assign {c, s} = x + y + z; endmodule I know that {c, s} means ...

If say I have the following wire set-ups, is the wire assignment all valid? wire[3:1] w; wire w1; wire [1:0] w2; A) w1 = w[2]; B) w2 = w[1:0]; C) w2 = w[1:2]; I am guessing that everything is ...

I have written two modules DLatch and RSLatch and i want to write verilog code to join those two.
