WebI don't know what your code is doing (I haven't fully reverse engineered it), but the normal solution is to unroll the bit assignment and do it bit by bit. So as an example if you had. a[index-1:0] <= b[index-1:0]; This would be illegal (if index was a reg/wire/signal) - the length of a[index-1:0] is not constant. You could, however, replace it ... WebMay 29, 2024 · If the slice size would be 3, groups of 3 bits would be created starting from the least significant 3 bits. Since we have an 8-bit input value, the last (leftmost) group will contain the remaining 2 bits. No padding or truncation is performed. The bit group reversing would then be performed, leading to the output value 8’b100_001_10. 4.
WebDec 14, 2024 · Verilog: bit slice vector twice. And we first select a 32-bit word out of it, and then select byte from this word, all using slicing: word = line [ (127-32*byte_addr [3:2])-:32]; byte = word [7:0]; That works fine. But if I wan't to combine both operators, in same line, it seems it is not permitted. Unfortunately I couldn't find a clear rule in ...
