Accelerating simulation verification for high-precision large-scale analog design circuit using SpectreX-GPU simulator engine

Abstract： With the development of semiconductor advanced processes nodes, the scale and complexity of integrated circuit designs is increasing, which brings great challenges to circuit simulation and verification. Accelerating circuit simulation with SpectreX-GPU has greatly improved the verification efficiency of large-scale, high-precision and complex circuit with advanced process nodes and has broken through the bottleneck of simulation and verification. SpectreX-GPU is a new engine in Cadence Spectre family with true spice accuracy. SpectreX-GPU expands simulator’s computation capability on CPU-GPU heterogeneous computing, combining the huge parallel computation capabilities of GPU with the complex operations of CPU. That makes SpectreX-GPU get high performance and balance between two capabilities and keep high accuracy same as SpectreX simulation engine. This paper introduces using SpectreX-GPU to accelerate simulation and verification in different types of cases on GPU device. It helps designers shrink simulation time, improve verification efficiency and coverage without accuracy loss.
