RTL level simulation of ALTERA_FP_FUNCTIONS IP (FP_FUNCTIONS Intel FPGA IP) requires a simulator that supports both languages.
Therefore, it is not available in VCS. Please consider using a Language Mixed simulator such as
VCS MX.
Alternatively, you can use ModelSim-Intel FPGA Starter Edition, which is provided free of charge by Intel PSG, as it is a dual-language simulator.
