I’ve never heard that distinction before.
It’s all emulation—either in hardware or software, in parallel or in series.
I used to work on simulation software professionally. The idea that simulation is parallel while emulation is serial is completely foreign to me, and I suspect foreign to others as well.
- icedchai 4y agoIt is foreign to me, for sure. I have been experimenting with FPGA-based retro systems for years (started with a MIST.) I still consider them "emulators."
- FullyFunctional 4y agoI have worked on simulators for most of my life and the GPs definition is not true. There's no formal distinction between the two, but conventionally emulation is more faithful whereas simulation is more high-level. Still, the two are used fairly interchangeably.
- rusk 4y agoTo me the distinction seems obvious: simulation reproduces the external behaviour of a system i.e from observers pov; emulation reproduces the internal behaviour. Typically the external behaviour emerges from this as a matter of course, but in many cases such a “bottom up” approach isn’t possible or even necessary.
