Platform designer Quartus 21 LCD and SDRAM problem - Platform designer Quartus 21 LCD and SDRAM problem Hello, i'm trying to update a quartus 18.1 project to 21.1 but when i use the platform designer the system says it can't find sdram-controller (altera_avalon_new_sdram_controller) and lcd-display (altera_avalon_lcd_16207). How can i solve this ? Thanks Eric Replies: Re: Platform designer Quartus 21 LCD and SDRAM problem Thank you for this information. I am having the same problem of trying to find a replacement SDRAM controller IP for the NiosII on the DE2-115 board (Cyclone IV). Is it possible to use a DDR controller such as the Intel AltMemPHY controller, for the SDRAM (which is SDR not DDR)?

If you want to continue to use these IPs, the latest Quartus version that supports these IPs is in version 20.1.

Replies: Re: Platform designer Quartus 21 LCD and SDRAM problem My suggestion is to search keywords like SDRAM or LCD in the platform designer IP Catalog, and choose a similar IP that match well with your design requirement. For further details, you may right-click the IP > Details. Each IP has documentation/user guide link attached with it. p/s: If any answer from the community or Intel Support are helpful, please feel free to give best answer or rate 9/10 survey.

Replies: Re: Platform designer Quartus 21 LCD and SDRAM problem Do you see any message when you try to upgrade the IP in the Platform Designer? My guess is the IP are most likely obsolete in the current Quartus version. https://www.intel.com/content/www/us/en/docs/programmable/683364/18-1/troubleshooting-ip-or-system-upgrade.html p/s: If any answer from the community or Intel Support are helpful, please feel free to give best answer or rate 9/10 survey.
