The Scan Ring Linker (SRL) by Intellitech is an essential IP module developed to reduce complexities and costs associated with multi-scan ring 1149.1 (JTAG) infrastructure in PCBs. The SRL effectively consolidates multiple scan paths into a single, high-speed test bus, streamlining operations by allowing independent testing and configuration through a unified JTAG interface. This enables more efficient diagnostics and test management across various devices on secondary scan chains, inviting notably lowered implementation costs and enhanced application reliability for engineers seeking robust PCB testing solutions.
