Re: Multichannel board
You can do this with a hierarchical design approach. Usually we do this if you have a large block which is repeated multiple times in a design. Check if the tool you are using supports this approach.
Re: Skin Depth
Skin depth changes in inverse proportion to the square root of operating frequency irrespective of the cross-section shape of the conductor.
Re: clock jitter
Jitter is defined the short-term variations (long-term or slow variations are called wander) of the significant instants of a digital signal from their ideal positions in time. In case of a clock next rising or falling edge may come after or before the accuate cycle time...
