Hardware Co-Simulation Blocks
out of the library and use it in your System Generator design as you would other Simulink
and System Generator blocks.
The hardware co-simulation block assumes the external interface of the model or
subsystem from which it is derived. The port names on the hardware co-simulation block
match the ports names on the original subsystem. The port types and rates also match the
original design.
Hardware co-simulation blocks are used in a Simulink design the same way other blocks
are used. During simulation, a hardware co-simulation block interacts with the underlying
FPGA board, automating tasks such as device configuration, data transfers, and clocking.
A hardware co-simulation block consumes and produces the same types of signals that
