This short article succinctly describes the basic logic emulation system that was the
first commercial large-scale, FPGA-based product success.

A relatively obvious use for FPGAs from the beginning was logic emulation.
But in the 1980s and 1990s, the capacity on a single FPGA was small
compared to typical ASIC designs. If you wanted to emulate your ASIC
design, you couldn't do it with a single FPGA. This set the stage for
multi-FPGA emulation systems.

This paper describe the Realizer, a multi-FPGA systems developed at Mentor
Graphics that provided proof-of-concept for multi-FPGA emulation systems
and led directly to the creation of QuickTurn, the first company offering a
commercial, multi-FPGA-based emulation system.
