ZYNQ temperature

[Tomas D.]

The uZed makes sense for low-volume, complex, relatively high-priced
products, 10 to maybe 50 units a year. It has the SOC, flash, SDcard,
DRAM, gB Ethernet, USB, power supplies, Linux, all that done and
working. The two boxes that we've done used all of that stuff. The
real downside is the ghastly Xilinx development software and horrible
support.

Future simpler products that have volume potential, we'll probably
switch over from our current habits (separate NXP ARM and Altera
chips) to an Altera SOC, now that they are available.

The two-chip thing works, but it wastes a lot of FPGA balls to provide
CPU access, and the FPGA register access is only 16 bits wide,
asynchronous and slow.

We use Altera Cyclone V SoC for automotive and so far - it's great. I can't
tell about reliability yet, but the support from Altera was amazing. We've
got exactly zero from X.

Good news. That's probably our future path.
