    Have you properly reference the SDI library as a user library?

    There was a change in the SDI core between Quartus 9.0 and 9.1. The reset port (rst) was replaced by individual resets for receiver and transmitter (rst_rx and rst_tx). It looks like wherever you are instantiating the SDI core, you are trying to use the old "rst" port, which no longer exists on the 9.1 version of the core.

    the SDI instantiation has both rst_rx and rst_tx ports, the error comes when fitter reads the SDI.sdc file...and looks like the .sdc file is not updated with the new SDI core.
