Tutorial: Using the USB-Blaster as an SOPC/Qsys Avalon-MM master

Hi all, I've put together a tutorial on how to use the Altera JTAG-to-Avalon-MM master and Altera Verification IP Avalon-MM BFM Master under both SOPC builder and Qsys. http://www.ovro.cal...

Hi Maik,

The main question really is, if I have to take care about anything but my data I would like to transmit? e.g., do I have to check myself for word alignment patterns although I have set this up in the transceiver phy component in QSys.

The answer is "it depends". Since it depends on how you've setup the transceiver. If you control both ends of the link, then you can use the 8/10B encoders and have the transceiver recover the synchronization.

If you do not use 8/10B encoding, then you have to synchronize the links yourself. For example, I have used the transceiver sync pattern detect logic, and hard-coded it to the start of a PRBS sequence and used that to synchronize lanes.

The main thing is, get it working in simulation first! :)

Cheers,

Dave
