Re: Advice for active FPGA forums

I am currently using an Intel Cyclone V, a 5CEBA2F23C8N and a LPDDR2 memory.

The reason for this initial choice is due to a Terasic development board
that used a Altera/Intel high end Cyclone V device with a functioning
LPDDR2 IP. Some code was breadboarded here.

Unfortunately I can't get the LPDDR2 IP to work on my PCB. I get errors
and I have given up.

So I have made my own interface. This 'can' function fine without error,
but as the design has become more complex I now struggle for the memory
to function at 225MHz clock speed, being the minimum speed I need for a
32bit DDR2 memory. I can select clock phase for the internal clock,
memory clock and DQS strobes.

I'm struggling with setting clock speed and appropriate timing where the
timing simply fails, despite setting the options to max speed. The
delays are simply too many ns.

In short I am throwing in the towel with a view to reconsidering
alternative architectures and FPGAs. I should be able to reuse most of
my code.

I was wondering if anyone could recommend a generic type of forum that
could assist with feedback. Yes I know there are AMD and Intel FPGA
sites but they are very specific to those makes.

There is comp.arch.fpga but that's pretty much defunct.

Any suggestions?
