3.4 SmartDebug Signal Integrity
(Ask a Question)SmartDebug signal integrity is invoked from debug transceiver. SmartDebug Signal Integrity helps to evaluate the reliability of a high-speed serial link using transceivers. The signal integrity GUI follows the same format as the IO Editor. For more information about software operation, see PolarFire FPGA SmartDebug User Guide. For more information about transceiver signal tuning, see AC483: PolarFire FPGA Transceiver Signal Integrity Application Note.
The Signal Integrity UI panel can be viewed in SmartBERT, Loopback Modes, Static Pattern Transmit, and Eye Monitor debug tabs. This allows the user to move between test operations and signal integrity tuning, hence, allowing the user to interactively test while making adjustments to the signal integrity settings.
Consistent with debugging techniques of high-speed serial channels, users utilize the SmartDebug GUI to select integrated test data streams and enable device embedded loop backs. This allows the active channel to be adjusted to match the users PCB losses and discontinuities. For more information about test pattern capabilities, see PRBS Generator/Checker.
