wire bonding rule of thumb
Hi Asic,
I use about 50mA/Pad for typical pads. The double bounding is necessary if you need to lower the bond indutance. That depends on the type of circuit that you have. For analog circuits is better to use as much pads as you can to have a more clean supply. This can be simulated to check the circuit behavor.
For digital circuits this is not so problematic. But depends on the speed of the circuit.
The number of pads limits the final silicon area, so a compromize is necessary.
