WebFeb 2, 2024 · Signs is defined as having a bit range of [2:0]. You can bit slice it with any range where the left index is higher than the right index. Swapping to have the right index larger than the left doesn't match the original definition. The LRM does discuss bit ordering of vectors somewhere, perhaps in section about bit slicing. 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. dachshund star puppies location
