IP: DDR3 SDRAM Controller with UniPHY

What is the largest capacity DDR3 device supported by the Arria V and Cyclone V FPGA UniPHY memory IP ?

Description

There is a bug in the UniPHY DDR3 IP which incorrectly allows a configuration for a single chip select 8Gbit DDR3 memory device with 16 row, 11 column and 3 bank address bits to be generated for the Arria® V and Cyclone® V hard and HPS memory controllers.

Workaround

The largest supported DDR3 device capacity configurations are as follows :

Hard Memory Controller and HPS Memory Controller :   4Gbit per chip select with an address configuration of 16 row, 10 column, and 3 bank bits.

Soft Controller :   8Gbit per chip select with an address configuration of 16 row, 11 column, and 3 bank bits.

For further information on the Arria V hard and HPS memory controller supported configurations, see Table 7-17: Features of the Arria V Hard Memory Controller in the Arria V Handbook and see Table 11-1: SDRAM Controller Interface Memory Options in the Arria V Hard Processor System Technical Reference Manual.

For further information on the Cyclone V hard and HPS memory controller supported configurations, see Table 6-14: Features of the Cyclone V Hard Memory Controller in the Cyclone V Handbook and see Table 11-1: SDRAM Controller Interface Memory Options in the Cyclone V Hard Processor System Technical Reference Manual.
