How to validate embedded hardware
noisepic , 08-08-2017, 12:47 AM
Hi,
After layout you must have plan for pcb bring up. I can list these stuff for pcb check:
- Measure voltage
​- Power up sequence
- Measure clock
​But in your embedded design still has USB port, HDMI, SATA, Ethernet, SPI, I2C..is there any good ways to validate the design of these high speed stuffs?
Thanks

If you have a lot of resources (especially money 
then you can buy some special equipment which will enable you to validate some interfaces (e.g. Ethernet, USB, ...). Here is an example: http://www.tek.com/how/automated-eth...s-video-tdset3
The other way to validate your board is a lot of testing. Usually you may want to run:
- testing in environmental chamber (running peripheral tests in different ambient temperatures)
- burnin / stress testing (running the interfaces in stress conditions e.g. extreme traffic between interfaces)
- long time testing (running some test for very long time e.g. months)
