Request for estimated release window of Avalon MM

[Marvin]

Hi Jim,

after searching the forum for a while, I noticed that you are working on the VC for the Avalon MM interface. My colleagues and I are very interested in this development, as our company has several modules that utilize such interfaces. We are eagerly looking forward to the release of this feature. Could you please provide us with a rough estimate of when this feature will be available?

Best Regards,
Marvin

Hi Marvin,
What Avalon MM capability are you looking for? Basic access is easy – registers. The curious and clever pipelining modes looked challenging when I looked at the interface. If you could enumerate what you need, it may break it loose.

Currently I am tied up working on Questa scripts due to their decision to make numerous non-backward compatible changes and have different variants in different tool versions (Questa Classic vs QuestaOne). I think I will wrap up on that shortly.

If you would like Avalon MM prioritized, you could fund its development. Part of my concern is investing in an interface that Altera is gradually replacing with AXI – I was actually expecting them to do that more quickly.

Best Regards,
Jim

Hi Jim,

Thank you for your quick response and the insights you provided. At this time, we are primarily interested in a VC for a “simple” AvalonMM interface, which includes the signals address, read, readdata, write, writedata, waitrequest and readdatavalid. For now we are not using the burst and response features.

As for the properties, we are using a subset aligned with our interfaces, with fixed values. With the exception of addressUnits, maximumPendingReadTransactions, and maximumPendingWriteTransactions we are using the default values.

Regarding your offer, we have discussed this internally and, unfortunately, are unable to provide funding for your work due to several reasons.

Best Regards,
Marvin
