7.5.1.5. Register Cascade Mode

When register cascade mode is enabled, the cascade-in port feeds the input to the register. The register cascade mode is used most often when the design implements shift registers.

You can change the register cascade mode by connecting (or disconnecting) the cascade in the port. However, if you create this port, you must ensure that the source port LE is directly above the destination LE.
