Description
Block Bit Slice returns a field of consecutive bits from the input signal. Specify the lower and upper bounds of the bit field using zero-base indexing in the parameters LSB Position and MSB Position. For the input word size parameter values LSB Position and MSB Position must satisfy the following constraints:
,
where and parameter values MSB Position and LSB Position accordingly.
