PRODUCTION DATA.
The JTAG interface is used to support boundary scan and emulation of the device. The boundary scan supported allows for an asynchronous TRST and only the 5 baseline JTAG signals (for example, no EMU[1:0]) required for boundary scan. Most interfaces on the device follow the Boundary Scan Test Specification (IEEE1149.1), while all of the SerDes (SGMII) support the AC-coupled net test defined in AC-Coupled Net Test Specification (IEEE1149.6).
It is expected that all compliant devices are connected through the same JTAG interface, in daisy-chain fashion, in accordance with the specification. The JTAG interface uses 1.8-V LVCMOS buffers, compliant with the Power Supply Voltage and Interface Standard for Nonterminated Digital Integrated Circuit Specification (EAI/JESD8-5).
