cyclone 10GX DDR3 (not DDR3L) fitter plan error "Error(20403): Global setting for OUTPUT_IO_TIMING_N - cyclone 10GX DDR3 (not DDR3L) fitter plan error "Error(20403): Global setting for OUTPUT_IO_TIMING_N Cyclone 10GX EV board example design of DDR3x40 on Quartus pro 20.4 After IP upgrade (also without upgrade ). The following error occurs at the fitter plan stage: "Error(20403): Global setting for OUTPUT_IO_TIMING_NEAR_END_VMEAS is not supported. Please use this setting with pin assignments." On quartus 20.4 error message web page there is no reference to that number. https://www.intel.com/content/www/us/en/programmable/quartushelp/20.4/index.htm#msgs/msgs/msgs.htm On quartus 17.1 (origin of that core) there is no problem. But cant use it because lacking of Ethernet stuff. Please advice Replies: Re: cyclone 10GX DDR3 (not DDR3L) fitter plan error "Error(20403): Global setting for OUTPUT_IO_TIMING_N Hi Yoram, Thanks to confirm about that. I will close this case. You can always file a new case in this forum if you got any problem. Thanks.

Thanks, Adzim Replies: Re: cyclone 10GX DDR3 (not DDR3L) fitter plan error "Error(20403): Global setting for OUTPUT_IO_TIMING_N Not a big issue. But when I did upgrade the IP, some lines in the QSF file were marked as obsolete by quartus . The unsupported setting of "OUTPUT_IO_TIMING_NEAR/FAR......." was not commented as expected. I did it manually as suggested in the first replay by sstrell . Replies: Re: cyclone 10GX DDR3 (not DDR3L) fitter plan error "Error(20403): Global setting for OUTPUT_IO_TIMING_N Hi Yoram, Do you still got the error message "Error(20403): Global setting for OUTPUT_IO_TIMING_NEAR_END_VMEAS is not supported. Please use this setting with pin assignments." ? What do you mean by your last feedback? Quartus 20.4 comment some irrelevant assignments when upgrade from previous IP versions but fail to comment the following: "OUTPUT_IO_TIMING_NEAR/FAR......." Can you elaborated it?

Check your .qsf file and any board trace model assignments in the Pin Planner.
