Project Title DDR RAM Controller for the Cyclone II FPGA Author Denis Pyatkov Abstract This project implements a DDR RAM controller at the RTL level for the Altera Cyclone II FPGA on a DE2 development board. A PCB board was also designed and fabricated to provide an interface between the FPGA and the memory chip.

1. Basic DDR Double Data Rate IO In Intel's older devices, primitives like ALTDDIO_IN, ALTDDIO_OUT, or ALTDDIO_BIDIR were available for simple DDR IO operations. However, I noticed that these IPs are not supported in Cyclone 10 GX. Is there a recommended way or equivalent IPprimitive in Quartus for implementing basic DDR IO on FPGA pins?

DDR and DDR2 SDRAM Interfaces in Cyclone III Devices Introduction Cyclone III devices support interfacing to both DDR2 and DDR SDRAM devices and modules. Altera provides the easy-to-use ALTMEMPHY megafunction to implement robust auto-calibrating interfaces to DDR2 and DDR SDRAM devices. You can configure this megafunction to

I think the Cyclone 5 supports LVDS DDR up to 320MHz in -C8-A7 devices Cyclone V data sheet, switching characteristics, High-Speed IO specs with demuxing to parallel data internally. This of course assumes that your data source can be clock synchronised to the FPGA if not proper Serdes blocks will be required.

signals between the FPGA and the DDRDDR2 SDRAM devices, how the FPGA pins should be configured to meet the DDRDDR2 SDRAM electrical and timing re quirements, and lists the number of DQSDQ pins available in the FPGA. In addition, this section also describes the architecture of the interface between the FPGA and the DDRDDR2 SDRAM memory.

Cyclone devices support various IO standards, including LVDS at data rates up to 640 megabits per second Mbps, and 66- and 33-MHz, 64- and 32-bit peripher al component interconnect PCI,

Hi everyone! I'm working with Cyclone V SoC and I'm trying to share part of HPS DDR between FPGA fabric and HPS. I have limited the linux DDR usage to 800MB through u-boot script to avoid any writing by FPGA on DDR portion that linux was using. I have placed a DMA in Qsys that reads samples from an on-chip memory and writes them to DDR through f2h_sdram interface. However the DMA never

hey to you all, im trying to interface to ddr3 component with the ddr3 uniphy controller ip . im using cyclone v soc development kit with quartus version 14.1 . i succeded to run the example design that intel provides and it runs successfully. the interface between the example driver to the ddr3 u
