What kind of FPGA package were you previously using?

Many FPGA CPU simulators attempt to be cycle-accurate for the purpose of architecture development, where the emulator has the leeway of treating instructions as atomic units and abstracting the rest.

Would have to ask my colleague about the details, but yes it is cycle-accurate. It is running 50 or 80 MHz, so it is expected to run slower.
