Hi, Experts
In 2.5 field solver(eg: Sigrity or SIwave), if i want to get DC resistance of 
interconnect, i use the two method:

1 Use FEM to calcute from DC to Fmax Hz, use the DC s parameter to get the S 
parameter

2 Use IR drop in the analysis to get the DC resistance

but the two method give two different DC resistance value, Which one i should 
trust?

Thanks.
