Scan Ring Linker is a flexible IP module designed for ease of insertion into CPLD, FPGA, or ASIC designs to simplify the JTAG test infrastructure. The SRL module is effective at managing 1149.1 (JTAG) complexities involving multiple scan rings. By combining multiple scan paths into a single high-speed test bus, it facilitates efficient testing and configuration through a singular external interface, allowing for independent testing and configuration of devices linked via secondary chains.
