Abstract: Based on the analysis of several typical simulation I/O architectures, a scalable distributed simulation two-tier I/O architecture was presented. It directly supported large number of simple digital displays(e.g 7-segment display) sharing a single data bus to decrease the hardwire complexity from O(n) to O( log n) for each of I/O controllers. This two-tier simulation I/O architecture has been proved to be able to meet the need of hardware-in-the-loop simulation with many good features such as real-time, scalability, fault-tolerance, maintainability and versatility.

Key words: process simulation, distributed simulation I/O, two-tier architecture, scalability, hardware-in-the-loop simulation
