About guard rings in cadence

[adityavoora]

Hai
how many contacts should be placed in p and n guard rings?

 

[erikl]

As many as possible.

 

[adityavoora]

I have to know depending on the circuit it should be how much?

 

[erikl]

Without knowing any of your parameters

• process size
• bulk or epi process
• type of circuit
• power consumption of circuit
• guard ring spacing
• guard ring width

... I'd advice: max. contact spacing < 5*contact_size .
