Intel: Even if the simulation model of ALTERA_FP_FUNCTIONS is generated with Verilog specification for FPGA with 20nm process or less, the lower module at the end is generated as a VHDL file. Can't you simulate with VCS?

RTL-level simulation of the ALTERA_FP_FUNCTIONS IP (FP_FUNCTIONS Intel FPGA IP) requires a bilingual simulator.
Therefore, it is not available in VCS.
Consider using a language mixed simulator such as VCS MX.
Alternatively, ModelSim-Intel FPGA Starter Edition provided free of charge by Intel PSG is a bilingual simulator and can be used here.
