Jonathon, Wade,
Regarding the Replay block controller and the recent change on 'master' to
Drop property, action, & mtu forwarding, there is one other modification
that I think makes sense. The Replay block is the only block controller
that implements "issue_stream_cmd" yet doesn't actually registe
Hi Rob,
Yup, that should fix the issue.

Thanks Jonathon!
This sure seems like a smoking gun. It doesn't seem like this is an
auto-generated file so it seems we could manually modify it to include
ports 2 and 3 in the same fashion as the N310 and then rebuild. Is this
true?

It looks like the problem is that while there is a 4 port interconnect
available, only ports 0 and 1 are hooked up:

This actually brings up a design suggestion: the Replay Block
I would start by double checking the YAML. For example, make sure the
MEM_ADDR_W parameter is correct (for E320 it should be 31, for 2 GiB) and
make sure each in/out port is connected the way you want.
If you share the YAML with me, I'm happy to take a look to see if anything
jumps out at me.

Thanks Wade,
I am helping Ofer Saferman with an issue with the E320 and a 4-port replay
block. Apart from your response (& Jonathon's response) indicating that
data rates should not be an issue, I have also come to the same conclusion
by trying some tests. After these tests, the issue now seems to
The E320's DRAM is pretty fast. It should have no problem keeping up for
your use case.

Hi Rob,
As long as the DRAM can keep up throughput wise, you should be fine in that
configuration. I think the E320 has a BIST you can run that reports the
throughput.
