It's the first time I perform DC-Drop simulation in HyperLynx on the power planes of my designs, and I started to feel how much TH vias get in the way of current path in power planes.
Intuitively, I started thinking about some instructions that I can send to the Layout Editor, that might help decreasing the the current density (red areas).
Some of these are just like the notes in the picture below:
- Rotating Vias
- Removing Extra TH Vias
- Re-Arranging Vias
The question is, are these changes really affect anything? and what else can I do?
