Description
The customizable LogiCORE IP Integrated Bit Error Ratio Tester (IBERT) core for AMD FPGAs is designed for evaluating and monitoring the Gigabit Transceivers (GTs). The IBERT core enables in-system serial I/O validation and debug, letting you measure and optimize your high-speed serial I/O links in your FPGA-based system. Refer to the Integrated Bit Error Ratio Tester 7 Series GTX Transceivers LogiCORE IP Product Guide (PG132) for more information.
The IBERT debug core lets you configure and control the major features of GTs on the device, including:
- TX pre-emphasis and post-emphasis
- TX differential swing
- RX equalization
- Decision Feedback Equalizer (DFE)
- Phase-Locked Loop (PLL) divider settings
You can use the IBERT core when you are interested in addressing a range of in-system debug and validation problems; from simple clocking and connectivity issues to complex margin analysis and channel optimization issues.
Related Objects
As seen in the following figure, the SIO IBERT debug cores are associated with hw_server, hw_target, hw_device, hw_sio_gt, hw_sio_common, hw_sio_pll, hw_sio_tx, hw_sio_rx, or hw_sio_link objects.
You can query the IBERT debug cores of associated objects:
get_hw_sio_iberts -of [get_hw_sio_plls *MGT_X0Y8/CPLL_0]You can also query the associated objects of specific IBERT cores:
get_hw_sio_commons -of [get_hw_sio_iberts]
Properties
You can use the report_property command to report the actual properties assigned to a specific hw_sio_ibert. Refer to the Vivado Design Suite Tcl Command Reference Guide (UG835) for more information.
The properties assigned to hw_sio_ibert objects include the following:
Property Type Read-only Visible Value
CLASS string true true hw_sio_ibert
CORE_REFRESH_RATE_MS int false true 0
DISPLAY_NAME string true true IBERT
NAME string true true
localhost/xilinx_tcf/Digilent/210203327463A/0_1/IBERT USER_REGISTER int true true 1
To report the properties for a specific hw_sio_ibert, you can copy and paste the following command into the Vivado Design Suite Tcl shell or Tcl Console:
report_property -all [lindex [get_hw_sio_iberts] 0]
