@Syakovac – The H/W and S/W teams can usually get started independently for the sake of project timing.As such, there is usually an opportunity to get the H/W built in alpha form and out in the lab.Of course the earlier boards have to be debugged anyway.If it has a uP or uC, then debug code has to be written to check it out.That's the time to write the test code for ALL the upcoming H/W + interface I/O.Many times the best time to write such code is when the Gerber files have been sent to the board house and you're waiting on the board to come back.Not until you have a built board can you work on it anyway.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
