Scan Ring Linker enables multiple 1149.1 scan rings

Key Features

  • High-Speed 1149.1 routing
    • Better signal integrity for TCK/TMS signals
    • SRL provides superior distribution of TCK, TMS and TRST signals permitting high-speed test operation greater than 40Mbs/sec. PCB engineering is also reduced as SRL eliminates complex test signal routing.
  • Reduces part costs
    • SRL can be deployed as a single IC on a PCB to reduce the need for buffers and logic level translators. SRL permits devices in secondary scan chains to have their IO pins configured at different voltage levels. A single SRL device controls each scan chain regardless of their voltage.
  • Flexible implementation
    • SRL simplifies design with plug-and-play IP that is easily embedded into a CPLD, FPGA or ASIC.
  • High fault coverage on difficult to test signals
    • SRL enables high fault coverage with pin level diagnostics for 1149.1 test signals -- TCK, TMS, TDI, TDO. Each TCK, TMS, TDI and TDO pin has a boundary-scan cell that can be used to test for shorts and stuck-at faults.
