That's a bit of a grey area. Some FPGA primitives work with inference only and finding those templates is hard. Some FPGA primitives have modules you can instantiate, but again finding all legal parameterizations will take you forever (it's never properly documented) and the simulation models rarely match the hardware behaviour so it's difficult to verify.
