The error message also says " Unknown range in part select.udp_data_in[((8 * i) + 7):(8 * i)]". But the range is known and depends only on value of i, the loop variable. So I feel it is known. I am confused here. Can someone explain please. " One way to implement this...
//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-...
On the other hand, casez treats ‘z’ (high impedance) and ‘x’ (unknown) as don’t care. It’s used when you want to match specific bit patterns while ignoring ‘z’ and ‘x’ values in the comparison. 23. How can a Sine Wave be produced using Verilog Coding? Sine Wave ...

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...
