Hardware-in-loop simulation architecture of vehicles was designed based on high level architecture (HLA) standard. Various precise timing techniques on Windows were analyzed in order to solve the real-time performance. Timing precision of timing techniques on Windows was tested with digital signal processor (DSP) and digital oscilloscope by using testing program on VC++. High-precision timer was appended to the manager federate based on HLA to control the simulation step and improve the realtime performance of the HLA simulation system. No datapackage error and data transmission delay appear in the simulation period, which ensures synchronization of the data transmission．
