//Creating a binary tree, so at each level the ranges are known. //I can’t comprehend why SV complains about illegal range of part select. The range of the part select is illegal: req_mux[LVL][NODE][(MAX_BKT_AT_LVL - 2):0] logic [SIZE:0][WIDTH-1:0][NUM_SEL-1:0][WIDTH-...

30. Can you tell me about the datatypes in Verilog. Verilog consists of a range of data types essential for design representation. These types serve distinct functions, which are as follows: Wire: Connects hardware components, modeling interconnections between modules. Register (reg): Acts as a ...

to indicate logic that is shutdown in low power simulations, out of range bit selects and array indices. Some designers assign X to signals to show that they are “don’t care” values, as a hint to the synthesis tool so it can assign either 1 or 0 to the signals during logic optim...
