Unless dealing in high speed digital, and the only way most cad proggies deal with that is to meander so trace lengths match, only the most costly commercial programs would bother to even attempt to lay out higher speed stuffs as transmission lines. Nice, I agree, but for a 1.5 x 2.125 board carrying 3 Honeywell HOA2001's, the premise behind visolate should produce usable boards at 112 khz maximum pulse rates. And I doubt that switching to outline mode would cause an improved output signal. Since I haven't actually laid out the board yet, waiting for Ed's 2 up printed copy of the manual to hit my mailbox (Thanks Ed), I do intend to design a src termination scheme to match 10 conductor ribbon cabling used as the hookup, on the board by incorporating a 120 ohm resistor in series with the 3 active signal lines. The mechanical room constraints of where it will be mounted might have the 10 pin header mounted straddling the edge of the board, but I'd rather have it laid down & pointing to one side or the other if there is room for it to clear the rest of the moving stuff doing it that way. I cut one piece of rat shack 2 sided board into 8 pieces, so I can afford to experiment a bit to optimize that. Then of course I'll have to cobble up the connections in the driver box, which since they are opto isolated on a C1G-4 interface card, will likely need an lm339 or similar for a buffer to drive the signals thru the opto's and back to emc. So another small board will need to be made for that.
