Why are there error/warning messages in the FASTSIM mode when simulated with Synopsys verification IP?

Description

In the FASTSIM mode, a simplified PMA abstract model is used to improve the overall simulation time for the F-Tile Avalon® Streaming Intel® FPGA IP for PCI Express.
The following error and warning messages are expected in the FASTSIM mode when simulated with Synopsys verification IP.
It is due to PHY calibration being bypassed in the simulation. It is safe to ignore the error and warning messages.
