I have an Arria 10 SoC DevKit that I'm using for a project. While studying the platform, I just tried to build the examples/golden_top/PRD/golden_top project that ships with the devkit sw download.For some reason, it will not build to completion. Synthesis appears to complete just fine, but planning fails with the following error: Critical Warning (18326): The design pin 'CLKUSR' has been assigned to CLKUSR pin location 'AP20'. Quartus Prime auto-reserves the CLKUSR pin for calibration of transcievers and certain IOs. If the pin 'CLKUSR' will not be assigned a 100-125MHz clock, you must remove the location assignment on it. Otherwise, to remove the critical warning use the QSF assignment 'set_global_assignment -name AUTO_RESERVE_CLKUSR_FOR_CALIBRATION OFF'. Error (12342): Can't turn on open-drain option for differential I/O pin DP_AUX_CH_N Error (12342): Can't turn on open-drain option for differential I/O pin DP_AUX_CH_P Error (16297): An error has occurred while trying to initialize the plan stage. Error: Quartus Prime Fitter was unsuccessful. 4 errors, 501 warnings Error: Peak virtual memory: 3134 megabytes Error: Processing ended: Thu Mar 30 10:37:18 2017 Error: Elapsed time: 00:00:42 Error: Total CPU time (on all processors): 00:00:42 Error (293001): Quartus Prime Full Compilation was unsuccessful. 5 errors, 1782 warnings Is this a known problem? Is there a workaround or fix? Dave
I tried compiling this before and it works for me without errors...http://releases.rocketboards.org/release/2016.10/gsrd/hw/a10_soc_devkit_ghrd.tar.gz I believe this is for Rev C of their board. I used Quartus 16.1 on linux machine to perform compilation.
