Coupling Capacitance

[cnu4u]

Can we reduce coupling Capacitance effect in a bus structure by placing two nets adjacently which are driven in opposite directions?

You cannot reduce the coupling Capacitance however, because the coupling capacitance is a function of permitivity, the spacing between traces and the length for which they run in parallel.

I am curious... if this is a bus how can you reverse the direction of signals in two adjacent lines ?

Sorry if I didn't mention clearly.
Consider a transmitter and a receiver connected by a bus. So there is a possibility of two way communication between them, like acknowledge signal or any such kind of communication. I'm asking about such scenario.

Look up crosstalk.

You only mention capacitive! don't forget inductive and conductive crosstalk.....
