Afaik 160Mbps is the theoretical limit from the FPGA to the PowerPC.

Hi all,
I'm having trouble generating functional borph executables, and i'm
hoping someone can help me figure out why. Since i'm targeting high
speeds, i can't use the bee_xps workflow. So here's what i'm doing:
1) synthesize a mdl via the bee_xps interface.
2) load the netlist into PlanAhead.

Hi Ron,
The adc083000x2 block requires some massaging.
First, when you drop the block into a design, right-click it and select
"Link Options -> Disable Link".
Then, select the block in your design (so that running gcb will return
the name of the adc block). Switch over to the Matlab window, and

Thanks for posting this, Glenn.
I was helping a visitor debug a useless Simulink error, and your
post "solved" it. We were following the original ROACH tutorial:

Matlab wasn't crashing for us, but whenever we tried to simulate
or compile, we got s

A casperite using the Chromium web browser was seeing a layout error
with the position of the navigation sidebar on the wiki. I've fixed
the problem. But, if the wiki layout is now broken for anyone else,
please email me.

IIRC, calling reboot with the -f flag solves this problem.

Casperites,
Last night, all services on casper.berkeley.edu were migrated from
casper1.ssl.berkeley.edu to casper2.ssl.berkeley.edu. We updated the
DNS records at 10am, so any future connections to casper.berkeley.edu
will be directed to casper2 (rather than casper1).
