Is there a reason why this module outputs N channels instead of N taps?
The Delay NTap module has a single output pin containing an N-channel wire buffer, where N is the specified number of taps. The delay of each output channel can be independently set.
Is this question about the design choice to have the module feature a single multi-channel output pin rather than N single-channel output pins? If N single-channels are desired, a Deinterleave module can be used to separate the multi-channel output.
