paul perry	Re: I have asked this a million times but again R.G. is right about autorouters... there is a lot more to (analog) layout than just 'connecting the dots'. The key to avoiding noise and instability problems is to think about which are the critical points on the circuit. And, think about earth return currents. And, remember that PCB traces have finite resistance. And impedance. Also, it's easy to forget that the rules apply to all the wires coming OFF the board, too.
