I get the following warning during synthesis each time. is it serious?
If it is serious can someone tell me how to correct this problem.
o2_2 is a 26bit signal
i did the coding in verilog Its basically for a set of 8 complex multipliers and o2_2 is one of the outputs . none of the other output signals are showing this warning.
If needed i can attach the verilog code as well.
Loading device for application Rf_Device from file '3s400.nph' in environment /opt/Xilinx.
