英文摘要：

The automatic test pattern generation （ATPG） of analog circuit network is the main focus and difficulty of mixed--signal testing. Based on the IEEE1149.4 standards, created models and testing methods for different analog circuit networks and proposed an AT- PG algorithm for analog extended interconnect testing. According to the method, a software test system was built. By compiling Protel netlist file, BSDL file, custom test flow file and custom BSC truth table file, extract the relevant information to complete the automatic gen- eration of test vectors. The results show that the test vectors generated by the algorithm can accurately control the conduction of the inter- nal switches, and form the exact test pathway, which means that they meet the requirement of analog extended interconnect testing.
