Re: use FPGA as and DDR2 RAM


i don't want to use the FPGA to access to the DDR2

but I'm rather interesting on emulating an FPGA as an DDR2

 

this is not the usual use for the DDR port capability of the FPGA

but i want to know if this is possible

infact i want only to emulate an DDR2 32kbyte
the FPGA contain an 32kbyte embedded RAM
and have already DDR2 pin and features

Re: use FPGA as and DDR2 RAM

Perhaps it is possible. But I don't recall seeing anyone doing this. Maybe someone else can chime in...

It is likely also fair to say that this wasn't a targeted usage model in the silicon or IP.

Re: use FPGA as and DDR2 RAM

Why bother?

unless you are thinking of trying to dual access the DDR2 memory for some reason.

Re: use FPGA as and DDR2 RAM

i will try to generate an DDR2 controller by xilinx

next i will try to modify it to function as  memory  (slave)

You're kidding, right?
