Why doesn't the rx_eqctrl_out value of the altgx_reconfig Megawizard change after channel reconfiguration in Cyclone IV GX, Arria II GX, Arria II GZ, Stratix IV GX/GT and Hardcopy IV devices?

Environment

  • Stratix® IV GX FPGA
  • Stratix® IV GT FPGA
  • HardCopy™ IV GX ASIC Devices
  • Cyclone® IV GX FPGA
  • Arria® II GZ FPGA

BUILT IN - ARTICLE INTRO SECOND COMPONENT
Description

Dynamic reconfiguration of PMA equalization settings, rx_eqctrl is not supported in channel reconfiguration mode. Dynamic reconfiguration of PMA equalization settings, rx_eqctrl must be carried out using the PMA dynamic reconfiguration mode.

This applies to Cyclone® IV GX, Arria® II GX, Arria II GZ, Stratix® IV GX/GT and Hardcopy® IV device families.
