15.5.1. Channel In (ChannelIn)

The ChannelIn block delineates the input boundary of a DSP Builder synthesizable Primitive subsystem.

The ChannelIn block passes its input through to the outputs unchanged, with types preserved. This block indicates to DSP Builder that these signals arrive synchronized from their source, so that the synthesis tool can interpret them.
