Just curious - what's the driver in the choice between Xilinx and
Altera? I've been using Xilinx for many years now and have been
fairly happy with them. At a previous job though, my colleagues
insisted that Altera was their preference. These days I don't know
much about the differences.
I think Chris is surrounded by Altera guys at the moment and he is
"conforming" :)
Resistance is futile......
Yes, we're members of the Altera family. I have Altera dev. boards
out the wazoo (and nothing from Xilinx), and the students use them in
several classes. That makes Altera the logical choice for us at the
moment, but I agree that well-written HDL code should port easily
between the two.
The biggest difference is Altera's use of PLL's vs. Xilinx's DLL's
for clock signals inside the FPGA. I'm not sure if that's going to
be an issue, but it's at least something to think about.
