Hi All,
For Power Integrity Analysis, I've calculated target DCR using Maximum Peak
current, Voltage droop (3%).
Then I have to calculate the maximum copper width for this power rail not
exceeding the target DCR. (Before Post Layout Analysis, this width
recommendation will be implemented in the layout)
Can someone share the formula which precisely calculates minimum power rail
width with input being target DCR, stackup data (like copper thickness).
Thank you,
Praveen
