They are looking into hardware and software design methods that will make the debugging effort as painless as possible. (The obvious real estate war between hardware, software, and mechanical engineers is in full swing.) They seem to be chasing their tails on several questions: They are looking into "debugging boxes" like the STEP Engineering box and the HP 64000 Logic Development System. They aren't sure whether they'll be able to use these things. They're worried about interfacing problems. Please mail me about your experience with these or other such units, or if you've designed your hardware to perform such functions, I'd like to hear about that too. They don't know how to write a debugger, they don't have experience with what goes into one, but they've been told that it would be nice to have examine/deposit, single step, etc... Tutorial information, books on the subject, user documentation which describes the features of "good" debuggers, would be appreciated. (I kinda loved our hacked up version of TOPS-10 DDT, but there must be other low level debuggers, or are there...)
