Hi- 1. Bond wire model you should get it from packing people, as a rule of thumb use 1nH/1mm with some seris resistance. I guess you have double bond, but please some mutual inductance also (~0.6). 2. Always do an Em sim for pad capacitance or calculate from metal cap density from foundry 3. . Add a small series resistance to the decap, Just add enough if it is more than enough decap is no more decap rather it is a resister, which will compromise supply noise.
This is the reason why always foundries makes decap std cells with non minimal length.
Best regards, Raj.
