7176 - The input signals CLKP and CLKN are not differential!
The simulation will continue to run, but this may not reflect the actual circuit operation.
Please check the CLKP and CLKN inputs, and rerun the simulation if necessary.
Description:
User will encounter the error messages during simulation using VCS tool. This is a typical response message from VCS simulator when a pair of differential clocks is fed to a DUT in a testbench.
For example, the message will be seen when running the VCS simulation for PCIe IP, MPCS IP, 10G MAC IP, SLVS-EC IP.
This is a known issue on VCS tool, not Lattice IPs simulation model RTL code issue.
Please ignore this warning message if functionality is correct.
