Current signal routing and voltage signal

[Akshaya katkar]

what care should be taken while routing voltage signal and current signal

 

[smruti_s]

While routing voltage signal, we should take IR drop into consideration, because even a small IR drop will also result in the loss of information contained in the signal. So we route voltage signal as less as possible.
For current signal, we should take EM into consideration.
Even if current signal is routed for long, there will be IR drop which will not affect current signal.
