A new event driven testbench synthesis engine for FPGA emulation

摘要

FPGA emulation has long provided the highest performance. However, designers have to restrict their coding style or transforming a huge unsynthesizable testbench into synthesizable one by themselves due to usually unsynthesizable testbench. We address this problem by presenting a new event driven testbench synthesis engine called BeEmu (Behavior-Level Emulator) to translate the behavioral testbench into synthesizable one for FPGA emulation. The proposed testbench synthesis engine is built by hardware constructs in terms of event driven model to correspond with testbench. Experiments demonstrate that our proposed engine can not only have a high simulation speed, but cover more HDL syntax as well.
