Not only is raw time wasted, but the learning feedback dissipates with those sorts of time lags. On a breadboard with trimpots, looking at an oscilloscope, one trains ones instincts rapidly, and things converge quickly. Remember the AC Wheatstone bridge "sliding null" ? It's a skill like riding a bicycle, that you never forget. We write some custom sims in Python or PowerBasic, because mixed-domain things run much faster with custom code.> >>I find it far better just to simulate the relevant circuit >>fragments for this reason. > >Might make you wonder how good the simulator you're using really is? > >I routinely simulate chips with THOUSANDS of transistors... might take >an hour or so... but my customers prefer not to commit $100K over a >seat-of-the-pants guess based on FRAGMENTS.There is no reason to sim an entire PC board, and it's usually not practical. If you understand all the bits, a board will work first-time without simulation or prototypes. Sims and protos are for the things that you don't understand. -- John Larkin Highland Technology, Inc lunatic fringe electronics
