elico copped a bit if flack on another thread for using the term.
FWIW my definition is that "design time" is any time before the product ships or at least before the point at which the code is locked and you are just stress testing with no debugging code in place. IE as it will run in the field.
"run time" (although I wouldn't use that term in this context) is actually after the above point but probably really "in the field" is a better expression.
So back to the original question, a new forum. Good luck with that because AFAIK not one single request of this nature has ever been acknowledged let alone implemented.
That said I think there is a real need for a method to show newbies how to debug code and hardware.
How many times do we tell people to print out a variable to see what it is? To disable code sections to isolate an error etcetera etcetera. (Apologies to Yul Brynner)
Actually I think a Saleae logic analyser should be shipped with every Arduino :), but that's another story.
