The abbreviation I know is "in-circuit emulator", but wouldn't know if that's what they were referring to
this. (but of course I almost never powered it up without thinking of Gibson's "black ice"; cf Burning Chrome)

And they usually looks and works like a Borg tentacles and assimilated production hardware, despite the "emulator" nomenclature, apparently by tradition from very early days of microprocessors when ICEs actually were alternate implementations for chips it emulates
