Configuring Lattice BSCAN2 Scan Path Linker
应用文章
Introduction
A boundary scan linker mux (multiplexer) device, also known as JTAG scan bridge or scan path linker, is a device that will be able to link or join multiple boundary scan chains into one single chain or multiple chain configurations depending on how the boundary scan linker mux device is configured. See Figure 1 below for a typical boundary scan linker mux connection.
The Lattice BSCAN2 allows multiple boundary scan chains or devices to be chained or isolated at the same time, by configuring access in accordance with the device family or as desired by the designer.
