Understanding Design Capacity in Hardware Emulators

A processor-based emulator vaguely resembles a software simulator in that the design database, stored in memory, is processed by a computing engine made up of a vast array of Boolean solvers or processors; hence the name of this emulator type. As in a simulator, the larger the memory, the larger the design the user can process. In a processor-based emulator, unlike a simulator based on a single algorithm (simulators can run in parallel on computer farms, but each computer executes one simulation algorithm), there are ultra large arrays of Boolean solvers running in parallel. This computing scheme allows for a somewhat soft limit in design capacity. A user can slightly exceed the maximum capacity specified by the vendor, maybe by as much as 10 percent, at the expense of a drop in performance that may be significant.
