Description
For AMD FPGA devices having GigaBit Transceivers (GTs), each serial transceiver channel has a ring phase-locked loop (PLL) called Channel PLL (CPLL). For AMD UltraScale and 7 series FPGAs, the GTX has an additional shared PLL per quad, or Quad PLL (QPLL). This QPLL is a shared LC PLL to support high speed, high performance, and low power multi-lane applications.
Related Objects
HW_SIO_PLL objects are associated with hw_server, hw_target, hw_device, hw_sio_ibert, hw_sio_gt, or hw_sio_common objects.
You can query the PLLs of associated objects:
get_hw_sio_plls -of [get_hw_sio_commons]And you can query the objects associated with a PLL:
get_hw_sio_iberts -of [get_hw_sio_plls *MGT_X0Y8/CPLL_0]Properties
You can use the report_property command to report the properties
assigned to a specific HW_SIO_PLL. Refer to the
Vivado
Design Suite Tcl Command Reference Guide (UG835) for more information. The properties
assigned to a shared QPLL type of HW_SIO_PLL object includes the following, with
example values:
