98% reduction in wiring
The Turret Control Computer (TCC) now houses 98% less wiring than before, and with the new circuit boards it takes just a few hours to assemble, whereas before, a new unit would have taken around 2 weeks to wire up completely. As well as the challenging mechanical constraints, there were some demanding PCB design issues to be incorporated into the design. These included differential pairs with tightly matched lengths and guard tracks around some very sensitive communication signals with complete over-under shielding. All of these were achieved with CADSTAR using the highly sophisticated Constraint Manager to drive the powerful P.R.Editor XR 2000 HS routing tool.
