Hello, I have a question about coupling capacitance....

Will the capacitance be formed between any metal layers ?? For example can it be formed between similar metal layers M1-M1.

I understand it can be formed between different metal layers M1-M2, M2-M3 etc... Also can the capacitance formed between M1-M5 M2-M6 like that ?

Once it is formed between the metal layers how will the signal transition on one layer affect the signal on other layer ? I understand the concept of "victim" and "aggressor" nets, but was not able to vizualize the exact effect of coupling capacitance..

Help would be appreciated....
 

Adding capacitance to a net will increased the net delay, impact setup and hold time.

As you are aware of aggressor and victim concepts, If a coupling cap is formed between two nets, this additional cap will also have to be charged or discharged. This affects the transition time and hence effect timing.
