METHOD FOR EVALUATING SYSTEM-ON-CHIP (SOC) HAVING CORE AS ITS BASE AND SOC STRUCTURE USING THE EVALUATION METHOD

摘要

A method for inspecting the cores of a system-on-chip (SoC) of a core base with high observability and high accuracy and an SoC structure realizing the inspecting method. In the method, a pad frame having two or more metal layers are provided to each core in an SoC, I/O (input/output) pads in a lower metal layer is connected to the top metal layer. Thus, all the I/O pads and power supply pads are provided on the top metal layer of the pad frame of each core. A test vector is fed to each core through the I/O pads of the top metal layer, and the response output from the core is received through the I/O pads to evaluate the core.
