    How to connect differents VDD together


      I'm designing a board with a PSoC4247BLE and I didn't find any info how to connect all the differents VDD (see my schematic in attachement).


      I mean, in my schématic I separated VDDR, VDDA, VDDIO and VDDD but how should I connect them together?


      I understand that each VDD have its purpose (digital, analog, IO and RF) but in my case they all will be at  3.3v.


      I looked at the schematic of the PSoC4BLE kit and they use 3 inductors but there is no value, what is the purpose? And why VDDD is connected to VCCD with a 0ohm resistor?


      Thank you very much
