Re: [casper] Timing error in dac_mkid or adc_mkid blocks

Hi,simon, I'm meeting the same issue.I failed to compile the mdl which used to be compiled successfully. In my opinion,The timing error may be a compile EDK problem.So I want to Disable the timing error first. I have tried some compilations,I put the XPS% xset enable_par_timing_error 0 when the

Re: [casper] casper Digest, Vol 90, Issue 7

Running casper toolflow on windows need a little modification of some .m files. I recommend using xilinx officially supported linux distributions, RHEL 6 or it's clone, centos 6, with casper toolflow. But if you insist running on windows, contact me and I can give you some patch. Good luck,

Re: [casper] casper Digest, Vol 90, Issue 7

Helllo , I have a simple question, my system configuration is windows7, and xilinx 14.7 with matlab2012a, but the casper_xps warns that it can not work with xilinx14.7, but i see on the casper website that Matlab R2012a/b Xilinx v14.x (Latest 14.7) is ok, so i am confused , is windows not ok

Re: [casper] Roach1 not working

HI Marc, Thank you for the reply, I am not seeing anything on the serial terminal. I have ordered a macraigor wiggler, I will try using that and see if the roach starts working. Thanks and regards, Nishanth On Mon, May 4, 2015 at 12:28 AM, Marc Welz m...@ska.ac.za wrote: On Wed, Apr 29,

Re: [casper] Recommended SFP+ transceivers with RJ45 interface (ROACH 2)

dear vishwa, there are no SFP+ to RJ45 cables, but you can purchase SFP+ to SFP+ cables, and use these cables to connect a Roach2 to another Roach2, or to a 10Gbit SFP+ switch, or a 10Gbit SFP+ network interface card in a computer. these SFP+ cables are made by several dozen vendors. for short

[casper] Spare 10Gb Cable?

Hi Casperites, I'm trying to run tutorial 2 to understand how the 10GbE works, but don't have a CX4 cable. Does anyone have a spare that I could borrow for a couple weeks? Thanks, Brad Dober Ph.D. Candidate Department of Physics and Astronomy University of Pennsylvania Cell: 262-949-4668

Re: [casper] Timing distribution over fiber

White rabbit is the version of IEEE1588 that locks bit clocks. Normal IEEE1588 doesn't do this. For this reason, (last I looked), there was no 10G implementation. 1G speeds is the highest White Rabbit implementation. The HW support for normal IEEE1588 is used to timestamp the packets without

Re: [casper] Timing distribution over fiber

hi dave, i also think distributing clock and 1 PPS is simpler than IEEE1588. some of the IEEE1588 and white rabbit experts are here at berkeley. see for example: http://chess.eecs.berkeley.edu/pubs/881/dreams.pdf my limited understanding is that 1588 phase locks the bit clocks of routers and

Re: [casper] Timing distribution over fiber

Hi We have a complete White Rabbit setup, including 5km fibre test reels. It is driven by a Meinberg Plenum 1 clock. We are quite happy to chat with anyone on this topic of phase coherence. As you all know, the hardware and firmware is all Open Source, so as Jason mentions, easy to incorporate. I
