Intel has indicated that the Qsys component for the SDRAM controller will no longer be available for use with the free software after Quartus V16.1. If you try to instantiate a SDRAM controller (using Qsys) in 16.1 it warns of this in the comment box for the component. I have not installed Quartus 18, but have looked at an install and did not see the SDRAM controller. Have I been mis-informed?

Hello,

For information , if your still use DE10-Standard (Cyclone V SoC dev board from Terrasic) as I do for a quick proof of concept design,

While recompiling old demo projects from Terasic for DE10-Standard, and in particular the SDRAM_Nios_Test as archived in the CD_DE10 (at this time generated under V16.1), confirm with Quartus prime lite V21, the legacy SDRAM controller generates an error, in revange with a fresh install of Quartus Prime Lite Version 17.1.0 Build 590, (downloaded April 2025) the QSys module still displayes as upgraded from 16.1 to 17., the initial SDRAM Controller: named "altera _avalon_new_sdram_controller " Version 17.1 and compilation is successfull with 0 Error.

Best Regards.

Fred
