I try to simulate PDN by lumped and distributed analysis with simple RLC and S-parameter model for the capacitor.
Please see the result in the picture below:
my Ztarget = 0.93 * 0.05 / (0.5 * 154) = 0.6mOhm.
Look into the result, I have some concerns below:
1 /. Why is there a big gap between blue line and red line? It mean which is more accuracy? simple RLC or S-parameter / SPICE model?
2 /. To tune PDN by changing the decoupling capacitor, which method simulation I should follow? Distributed or lumped analysis?
Thank you so much.
