EM extracted parasitics for your pad:
Pad capacitance to ground is 0.18pF, which is small compared to the varicap path.
Series inductance from "bottom side" to "diode side" is 0.6nH (per path).
You can go back to your "ideal" schematic, insert these parasitics and see if that is close to the EM results with pads.
Can you say me how did you calculate these values?
