[casper] 10GB Ethernet
Folks How does the 10GB Ethernet work on the Roach boards? In most Xilinx applications, the 10GB ethernet is generated by Xilinx IP blocks that have an expensive license, on the order of $22k. I have heard nothing about licensing fees for the 10GB Roach yellow block. Any ideas on this? Tim Madden Argonne Lab

We have implemented our own 10GbE core. It's free open-source! Jason On 10 Feb 2014, at 16:50, Madden, Timothy J. wrote: > Folks > > How does the 10GB Ethernet work on the Roach boards?

Re: [casper] 10GB Ethernet
We were using Xilinx's free XAUI core for the PHY layer at one time... I'm not sure if that's still the case though because there was an effort to write our own at one time. It's been a while since I dug that deep into the toolflow.

Implementing a 10GB core is no easy task, considering you must sync. many serial transceivers together. Cool. Good job.

Roach in a balloon Just an idea if some engineer wants alot of work to do. One could put a whole ROACH into a tiny circuit board these days using the new Xilinx ZYNQ chips. It is a multi-chip module w/ high end Xilinx and 2 ARM cores. It would of course require recompiling all the ROACH IP for use w/ ARM. But the resulting hardware would be small, and not use alot of power. It would be a fun project.

Re: [casper] casper Digest, Vol 75, Issue 8
hi tim, there is a low power, low cost, roach like board under development, called SNAP. SNAP uses a kintex fpga, has two 10Gbit ports, some adc's and frequency synthesizer on board, and one zdoc for external adc's. info at: https://casper.berkeley.edu/wiki/DAB-HERALD best wishes, dan On Mon, Feb 10, 2014 at 7:20 AM, Madden, Timothy J. wrote: > > > Roach in a balloon > > Just an idea if some engineer wants alot of work to do.
