Would the existing electrical specifications, namely the Trace Lengths, for the
Standard PCI form factor still apply to CPCI and PMC form factors ?
The main considerations is to compensate the 2.5" +-0.100 trace length PCI
Clock on Multi-Layer PCB's.
Many of the Industrial quality boards are Multi-Layer, wouldn't there be a
timing specification instead ? As the Flight time on the Inner Layers
are faster than the outer layers or is this considered insignificant ?
