another MicroZed project

Started by John Larkin February 4, 2015

Another board:

https://dl.dropboxusercontent.com/u/53724080/PCBs/P350_12.jpg

The microZed compute platform plugs into the middle. The application
board has eight DAC channels with filters and amps, two ADC inputs,
power supplies, BIST, stuff like that. We put some parts under the
Zedboard, simple stuff that shouldn't need a lot of probing or
anything.

The only problem with MicroZed is that it uses a Xilinx FPGA, which
requires the Vivado software, which really sucks.

Zynq and Vivado is big and complicated so of course it has a steep learning curve but sucks that's a strong word have you ever used it yourself? -Lasse

No, but I have two guys working on this project, both pro FPGA jocks. *They* think it sucks. The support sucks, too. -- John Larkin Highland Technology, Inc picosecond timing precision measurement jlarkin att highlandtechnology dott com http://www.highlandtechnology.com

Yea, maybe it could be replaced by a PIC 18F?

For an industrial product I would be severely worried about these things being available 10 years from now. Its even hard to find some old X FPGAs. Why not make your own 'Zed' board?

they'd have to be very old, as the processes get discontinued the price just increases so only those who really really need them will consider buying
> Why not make your own 'Zed' board?
Unless you make a lot it is hard to compete with the price, making your own board and plug that in instead is always an option later You'd probably want to do it as plug-in anyway, you pretty much need to do 10 layers and blind vias to make the PCB -Lasse

uZed is open source, Gerbers and all, so we could make them if we had to. Avnet is guaranteeing some years of availability. The FPGA itself is probably the biggest liability. It it convenient to have all that stuff done. FPGA, ARMs, dram, flash, ethernet, USB, power supplies, boot loader, Linux. -- John Larkin Highland Technology, Inc picosecond timing laser drivers and controllers jlarkin att highlandtechnology dott com http://www.highlandtechnology.com

We are doing a lot of serious waveform generation and filtering in the FPGA, clocked at 250 MHz. And the dual ARMs, running at 600 MHz, will be working hard too. Not PIC territory. -- John Larkin Highland Technology, Inc picosecond timing laser drivers and controllers jlarkin att highlandtechnology dott com http://www.highlandtechnology.com
