When I use a custom configuration for my Opmode block, I try to select PCIN>>17 or P>>17, but the drop-down menu has the options PCIN>>17 instead of PCIN>>17 and P>>17 instead of P>>17. When I use these options the following error occurs:
"The following error occurred with the opmode block:
Illegal parameterization: Z_mux
Unsupported Z mux operation. Z_mux is currently set to PCIN>>17"
This is a known issue with the opmode block for the DSP48 custom setting.
Contact Xilinx technical support for a work-around for this issue.
