JESD204B FPGA Debug Software Accelerates High-speed Design

Free, on-chip, 2-D statistical eyescan software enables fast in-system verification of high-speed data converter-to-FPGA signal integrity.

Oct 11 2013 - Norwood, MA
  • Analog Devices, Inc. (NASDAQ: ADI), a global leader in high-performance signal processing technology, released today a FPGA-based reference design with software and HDL code that reduces the design risk of high-speed systems incorporating JESD204B-compatible converters. Called the JESD204B Xilinx Transceiver Debug Tool, it supports the 312.5 Mbps to 12.5 Gbps JESD204B data converter-to-FPGA serial data interface and Xilinx® Inc., 7 series FPGAs and Zynq®-7000 All Programmable SoCs. It is available at no cost with ADI converters and provides an on-chip, 2-D statistical eyescan that helps designers of radar arrays, software-defined radio and other high-speed systems more quickly verify the signal integrity of JESD204B data converter-to-FPGA using gigabit transceivers.

    “The Analog Devices JESD204B Xilinx Transceiver Debug Tool provides on-chip eyescanning that augments the test and measurement process by statistically determining signal integrity inside the FPGA,” said Revathi Narayanan, High Speed I/O product manager, Xilinx. “Where other techniques probe the outside of the FPGA package and acquire the signal before it’s been processed by Xilinx’s automatic gain control and equalizer blocks, ADI’s approach yields a more accurate result by utilizing the Xilinx transceiver on-chip eyescan feature to allow developers to monitor the signal integrity and design margin on their JESD204B links inside the FPGA.”

    ADI’s reference design gathers data directly from the on-chip RX margin analysis feature in the 7 series IBERT core and manages the data locally inside the FPGA or one of the ARM® dual-core Cortex™-A9 MPCore™ processors, displaying the data on an HDMI monitor or over Ethernet to a remote monitoring station. Typically, other scanning tools measure signals off-chip and require costly test and measurement equipment or transfer the data back over JTAG to be viewed on a host/development PC in the lab.

    ‘Live’ Data Capture Monitors Equipment Health

    Alternative scanning tools typically measure high-speed data links by generating a pseudo-random bit stream (PRBS) that is checked for bit-level correctness in a closed development environment. This approach does not describe how well the design is performing or if it might be on the verge of failure. ADI’s reference design measures link robustness using actual JESD204B serial data running to the FPGA. This use of “live” data enables signal fidelity to be monitored even after the design has been deployed in the field, which allows for real-time and predictive maintenance over the life of the product.

    The boards of directors of both companies have approved the transaction, which is expected to close by the end of October 2013, following the satisfaction of customary closing conditions. Tax assessments and any additional closing costs will reduce the net amount of proceeds received by ADI from the transaction.
