Connecting New Ports in the GHRD Module Instantiation
In an earlier step, you added new ports to the top level GHRD module, by exporting the pr_handshake interface conduit. You must connect these ports in the GHRD module instantiation before the design can be synthesized.
Open the GHRD top level module, which you generated in earlier steps, as shown below.
The new pr_handshake ports are highlighted below. The conduit interface exported in the Qsys design consists of the four PR Start and End request/acknowledge handshake signals shown.
The PR Start and End request/acknowledge handshake signals are required by the Intel® partial reconfiguration freeze controller. You must directly connect these signals in the top level design for proper freeze controller functionality. The connection is shown below.
