It is termed prototyping but your FPGA will not contain the same implementation or even logical representation of your ASIC. It can't. The technologies employed are too dissimilar.

Not true. There's a ton different logic structures an FPGA cannot replicate. They weren't designed to handle complex clock switching and clock gating nor lots of analog or even some asynchronous stuff. Their built in SRAM usually works much differently too. But all close enough for an approximate prototype
