Re: Standard Test Waveforms


A few of us have been discussing something like this
data file you've described. We did something similar
during the 1GE project. We were kind of waiting until
we had a better description of bit ordering through
the blocks and I think this draft of the standard
provides a good basis for this.


Anyone who'd like to contribute please contact me
privately. I'll be looking for input regarding the
interfaces we want to cover, the format of the data
files and volunteers for providing data files and
verifying other's data files.

To all you gung-ho engineers out there, make sure
you run this past your manager before you start
contributing. Please make sure they don't consider
any work you do as part of your company's IP as
the goal of this work is to make it available to
the entire P802.3ae community.
