WebInitialization of the Boundary Scan Chain After loading the BSDL files, the boundary scan chain should be initialized. Some ICs may require a reset via TRST_N (e.g. to latch the device into boundary scan mode). Both commands will reset the TAP controllers for all ICs in the boundary scan chain and halt in Select-DR-SCAN state. WebScan chain is a technique used in design for testing. The objective is to make testing easier by providing a simple way to set and observe every flip-flop in an IC .The basic structure …
