Yep, emulation is huge. HAPS by Synoosys for example has a bunch of huge Xilinx FPGAs in there. I've never used one, but apparently it takes care of splitting the huge ASIC design over the array of FPGAs so it looks like a single chip, and can run at 100s of MHz, so way better than simulation that could be a few kHz at best
