General Description: When generating CORE Generator Bus Multiplexer v3_0 with BUFT-Based type and with the output option "Latency 1" specified, I encounter the following CORE Generator error:
ERROR: Customization parameter rule checks failed. Terminating core elaboration: Illegal Value 1 specified for variable latency ERROR: SimGenerator: Failure to set Sim customization parameters for core Bus_Multiplexer ERROR: Elaboration failure for core Bus_Multiplexer ERROR: Elaboration of core Bus_Multiplexer failed.

The BUFT-based BUS Multiplexer is non-registered; therefore, it is impossible to generate a core with a latency of anything other than "0". However, due to a GUI problem, it is impossible to select anything other than "1" for the latency.
To work around this, make the latency "0" by selecting the Output Option "Non-Registered." This selection may already have been made by the GUI when you selected "BUFT- based," but clicking on "Non-Registered" again should change the latency to "0".
This problem is fixed in the D_IP3 IP update that is scheduled for March 2001.
