Crosstalk:
Switching of the signal in one net can interference neighboring net due to cross coupling capacitance. This affect is known as cross talk. Crosstalk can lead to crosstalk-induced delay changes or static noise.
Double spacing => more spacing=>less capacitance=>less cross talk
Multiple vias => less resistance=>less RC delay
Shielding => constant cross coupling capacitance =>known value of crosstalk
Buffer insertion => boost the victim strength.
Net ordering => in same metal layer change the net path.
Layer assignment=> Change the metal layer of two nets if possible. (One s/g in mtl3 and one signal in 4).
