摘要
PURPOSE: An IEEE 1149.1 jtag standard extension method and a device thereof are provided to reuse an existing boundary scan architecture, thereby considerably reducing wiring congestion.;CONSTITUTION: A boundary scan architecture(10) is arranged on an integrated circuit. A plurality of functional registers(12) and microphone chip logics(20) belong to a microchip area which include the functional circuit of the integrated circuit. A plurality of input/output units(14) are arranged in a serial communication chain. The serial communication chain is located around the boundary of the functional circuit of the integrated circuit.;COPYRIGHT KIPO 2010
