The invention discloses a universal 
computer simulation testing platform based on a CPCI 
bus. According to the universal 
computer simulation testing platform based on the CPCI 
bus, time is unified, expansion is convenient, and the universality is high. The universal 
computer simulation testing platform based on the CPCI 
bus comprises a CPCI bus 
chassis, expansion boards, a CPU module and a PKIO module, wherein the CPU module and the PKIO module are arranged in the CPCI bus 
chassis and connected with the CPCI bus. A secondary bus which meets the H.110 standard is formed on the CPCI bus 
chassis by means of expansion through an arranged J4 slot. Each extension board is connected with the CPCI bus and the secondary bus. The CPU module controls the expansion boards and the PKIO module through the CPCI bus. The PKIO module is connected with the secondary bus and is used for providing unified 
time mark signals for the expansion boards through the secondary bus. The 
time mark signals are generated through the PKIO module, synchronous 
clock signals are transmitted through the secondary bus, 
shunting transmission of control instructions and time signals is established, 
synchronous control over the expansion boards is achieved, and real-time 
simulation of a tested object is completed.
