FPGA-based coprocessors simplify ASIC emulation

With compressed time lines and intense pressure to get it right the first time, ASIC emulation has become an increasingly critical part of the design process. Designers have historically had few good options for emulating ASICs, however. Now, many are turning to a new tool: FPGA-based coprocessors. These reconfigurable coprocessors are allowing designers to eliminate many of the issues associated with conventional ASIC emulation and deliver more accurate designs more quickly and with less effort.
A coprocessor approach also allows for much faster startup times than building hardware from scratch. In addition, because the reconfigurable processor has a tightly coupled, low-latency link with the CPU, designers can exercise the emulated hardware they create at very high speeds--orders of magnitude faster than a software simulator.
