摘要
PURPOSE: A JTAG scan chain system comprising a scan chain utilizing a JTAG function is provided to perform the JTAG test while the JTAG scan chain uses an emulator or a programming function.;CONSTITUTION: A CPU(120), a programmable logic(130), a JTAG(Joint Test Action Group) chip(140), and a dotter board connector(150) are connected to a connecting line receiving TDI from a JTAG connector(110). The JTAG TOD outputted from the connection line is outputted to the JTAG connector. The connection line is formed into the JTAG connector between a third switch and the programmable logic. A CPU TDO output signal is applied to the JTAG connector and a CPLD TDI signal is applied in the programmable logic.;COPYRIGHT KIPO 2011
