Hi Jason
Yes, you have the right of it. The Simulink yellow block 10GbE core is
a black hole into an ethernet cloud. We don't try to model an entire
multi-board system, but rather just the design at single board level.
Modelling networks is a complicated affair and entire software suites
have been written to try'n address the issue. We have not broached it
yet :)

Hi,
This is the first time I'm posting to this mailing list, so allow me
to introduce myself. My name is Jason Zheng, and I am an FPGA design
engineer at JPL. A couple of weeks ago I attended the CASPER
workshop at JPL, and have started to play with the CASPER libraries.
My main interest is to infuse CASPER cores into the instrument
design at JPL.
I've been playing with the 10GE UDP core for a while, and took a
look at the VHDL source code. Comparing the simulink model with the
VHDL source code, I noticed that the simulink model hid the physical
interface (XAUI_XXX) from CASPER users. The simulink model only
shows the internal datapath ports and the LED outputs. It doesn't
seem obvious to me how to run a simulink simulation with the UDP
core fully modeling a computer network. Am I missing some key
information? Or is the UDP core meant to be a black hole/hose only?
cheers,
Jason Zheng
