WebApr 5, 2024 · We can write comments in two ways. When we want to skip one full line during execution, we specify the comment using //. Verilog jumps from that point to the end of the line. To write multiline comments, we start with /* and end it with */. We can see how comments are used in Verilog: WebComments in Verilog use a // for one line or a /* and */ when spanning multiple lines, just like C. Notice in Appendix A, the module name of the counter is called count16. So, Count16 is used to place an instance of the counter in the test bench with the instance name U1. The name U1 is arbitrary, and the instance can be given any descriptive name. WebThe verilog has one input for feeding clock and one output register for LED output. The 32-bit register for counting the clock cycle. We are giving 100MHz clock to our design and 32-bit register is enough for counting 100 mega clock pulse. If clock frequency is 100MHz then counting this will require 1 second of time. ... Add Comment ... soft oversized hoodies lavendar
