We found the 5 settings below can influence PDN simulation result.
1. High-accuracy mode
2. Minimum void size
3. minimum metal-area size
4. defeature metal areas
5. defeature resolution
Is there some recommendations or rules of thumb for HDI design?
The minimum size of our board is about 3mil. How to get the simulation result close to the real board?
When decreasing the void/metal/defeature size, the PDN result is not always decreasing or increasing.
