In Verilog, both == and === are used to compare things, but they do it in different ways. The == operator checks if the bits in two things are the same, even if the sizes are different. It’s good for comparing things of different sizes. On the other hand, === is more strict...
13// depends solely on the bits below it, down to the imaginary bit. It flips 14// only if all these bits, taken together, match the pattern 10* (a one 15// followed by any number of zeros). 16 17// Almost every non-imaginary bit has a submodule instance that sets the 18// b...

If the highest digit of a certain number is x or z, then the system will automatically use x or z to fill in the higher digits that are not occupied. If the highest bit is otherwise, the system will automatically use 0 to fill in the higher bits that are not occupied. ...

Case statements are more convenient than if statements if there are a large number of cases. So, in this exercise, create a 6-to-1 multiplexer. When sel is between 0 and 5, choose the corresponding data input. Otherwise, output 0. The data inputs and outputs are all 4 bits wide. ...

Thanks to [Anonymous] for the tip! Bringing The PIO To The FPGA May 22, 2023byMatthew Carlson10 Comments We’ve seen some pretty incredible hacks using the Raspberry Pi 2040. However, one of the most exciting bits of hardware onboard is the Programmable I/O (PIO). Not content with it...
