Abstract :
This paper presents the multithreaded programming techniques used in parallelizing SPICE3 circuit simulator. Two approaches in multithread programming are proposed to parallelize SPICE3 simulator program in multi-core SMP systems. We have used OpenMP and Pthreads, two shared memory programming-interface standards, to realize our approaches, in order to redesign the SPICE3 device-loading functions. We have presented case studies using SRAM circuit as our input data, which consists of MOS devices that is modeled by a widely used BSIM3 model. Experimental result exhibits the performance improvement for the multithreaded implementation of SPICE3 circuit simulator.
