Abstract: This article proposes a new hardware testing system for system-level testing of SOC chips. The new system introduces FPGA as an auxiliary testing chip, uses PC as the medium between the chip sorting machine and the testing hardware for testing, and records the test data. After the introduction of the new hardware system, the existing SOC chips are used as samples to demonstrate the benefits of chip quality control from testing coverage, testing time, and defect analysis.
Key Words: System chip; Chip testing; Hardware design; Quality improvement
0引言
系統(tǒng)級芯片(SOC)也稱為片上系統(tǒng),即在一顆芯片上,集成了邏輯模塊、存儲模塊、模擬模塊、模數(shù)混合模塊等。(剩余3656字)
