When simulating the outputs from the Virtex-6 FPGA GTH Transceiver Wizard in NCSIM, you might see failures similar to the following:
ncvlog: *E,NGITEM (../../example_design/v6gth_wrapper_gth_init.v,142|14): Not a valid generate item: 'parameter_declaration' [12.1.3(IEEE 2001)].
To work around these errors, "parameter" declarations need to be changed to "localparam".
For example:
parameter [3:0] TXBUFRESET = 4'b0000;
needs to be changed to:
localparam [3:0] TXBUFRESET = 4'b0000;
