Why am I not able to enable "Enable continuous write of all the words needed for reconfiguration" option in ALTGX_RECONFIG Megawizard?

Environment

  • Quartus® II Subscription Edition
  • BUILT IN - ARTICLE INTRO SECOND COMPONENT
    Description

    You are not able to enable "Enable continuous write of all the words needed for reconfiguration" option in ALTGX_RECONFIG controller due to a software bug in Quartus®  II 11.0 and 11.0 sp1 software.  ALTGX_RECONFIG Megawizard allows you to check-off this option, but this setting does not take affect internally.  If you re-open ALTGX_RECONFIG Megawizard, you'll find this option un-checked, even though you had checked it off previously.

    To workaround the problem, change the directory to the folder containing the generated ALTGX_RECONFIG Megawizard file and run the following command at the DOS or Linux prompt:

             qmegawiz –wiz_override="enable_full_write=true,data_latency=2" <altgx_reconfig file name>

    This issue will be fixed in furture software versions.
