With this Easy PDN Tool, also called as TY-PDN Tool, you can easily calculate and compare the impedance-frequency characteristics not only of single capacitors, but also of combinations of multiple parts, using S-parameter files (.s2p).
You will not need an expensive simulator nor complex operations. You can easily calculate the total impedance of PDNs (power distribution networks) in a short time with just only this tool. Even beginners can use it because of its simple usage.
As it is download type software, you can operate it even without network environment. Please use it after enabling the macro function of your Excel.
