This is a simple n-bit wrapping up counter. The n parameter can be changed to make this 4, 8, bit counter were n = – 1. The CLK signal can be any signal you want and will increment the value of the counter on the positive edge of a pulse, RST is the negative edge reset signal which will reset the counter to 0 or any number of your choosing also be sure to change the.

I think you slightly misunderstood the description of the multiplexer. You do not have to create the pulses inside of it, so the numbers 500000000, should not appear there.Instead, the multiplexer should not care about what its inputs mean. It just has to connect one of them to the output, depending of the value of the select input. Like in the 7-segment decoder, you can use a case statement to model the multiplexer and it could look like this: module mux4to1 (sel, seg0, seg1, seg2, seg3, delay);input 1:0 sel;input seg0, seg1, seg2, seg3;output delay;always @(.)case(sel)/.
fill in the appropriate Verilog code which expresses this:if `sel` is 0 - `delay` is `seg0`if `sel` is 1 - `delay` is `seg1`and so on./endcaseendmoduleYour up/down counter needs an additional clock input. The updown input should be a single bit, not eight bits.The code for the counter should look similar to that of the pulse generator. In every clock cycle, one of the following should happen:. if pulse is 0, the counter stays as it is. if pulse is 1 and updown is 1, the counter is increased by one. if pulse is 1 and updown is 0, the counter is decreased by oneYour pulse generator and 7-segment decoder seem to be okay.
I need help in my project which is a counter that counts up or down from 0 to 20. I already did my counter code and it's working in active HDL. But now I need to show the numbers in 7-segment in nexys 3 FPGA board.I have the code of the segment, but I have a problem when I call the module of segment - it is giving me an error in active HDL.
