Abstract: Pin Electronics（PE）,one of the core components of digital IC and SOC test systems,is usually used in testing logic functions of digital ICs.An excellent PE card is pivotal in developing digital IC and SOC test systems.The paper introduces a design method of digital pattern generator based on PCI bus.The digital pattern generator model generates diversified test patterns to meets the test demands of high-,medium-and low-end digital ICs with DDR3 as memory and FPGA as customized logic processor.In the paper,the design method of collect and record module/sending module,cache module,logic control module and PCI interface moduleare highlighted.

Key words: PCI bus, digital pattern generator, DDR3, FPGA
