Manycore architecture is the trend of system design. However, manycore simulators face the important issue than general multicore simulators is simulation speed. Several studies provide a FPGA simulation methodology to solve it, but they almost do it by providing a new internal design of core. And some of them don't care the correctness without interconnection simulation. This paper provides a PVCT module and NIP methodology to solve these two issues. According to our experiment, we could provide a 91.4 MIPS simulation performance averagely with Splash2 benchmark by three physical cores. The number of three is decided by capability of Xilinx XC2V8000 FPGA chip.
