In this paper, we propose a lock-free architecture
to accelerate logic gate circuit simulation using SIMD multi-core
machines. We evaluate its performance on different test circuits
simulated on the Intel Xeon Phi and 2 other machines. Comparisons
are presented of this software/hardware combination with
reported performances of GPU and other multi-core simulation
platforms. Comparisons are also given between the lock free
architecture and a leading commercial simulator running on the
same Intel hardware
