Hi,

How is the resistance calculated in terms of link length and multi-links ?
is it link resistance R=ρL/A, where A=w*t ?

I am looking at cadence schematic, where it has two options :

Calculate R, when W/L is specified and

Calculate W/L, when R is specified

What is the equation used to find the R. and where do you find the value of thickness.

Any help in this regard would be appreciated.
 

This is not a cadence option, it is a design kit option. U can find the equation from the process documents.
 

could you please elaborate ?
as i see, its the option in cadence when u query on the resistor.

it would be helpful if you could specify the formula used in calcuating the R, in terms of W and L
 

The calculation is done via callback routines. These should be minimum readable to you. The designkit will be installed somewhere, there you can find them in source code. I think the extension is *.il for interpretated skill code. The calculation are triggered if you enter values in the CDF fields.
 

PDK can do that!!!!
