The most obvious point is grounding that you point out.
In the schematic, you use idea ground to do simulation.
In the layout, the ground is not as ideal as what you think. You use a ground plate actually.
I suggest you use ground via in schematic to do simulation. For example, L1 is grounded in the schematic. You change it to add a via then connected the via to ground. Doing this way is bit closed to reality.
Layout is same. For example, L1 is connected to a single ground via, you just need to connect a single ground via to L1. Don't connect the L1 to a ground plate as before. |
