PWR track vs PWR plane

Thanks Robert, I shall watch this video.

Looking forward to a video where you use simulation program (e.g Hyperlynx) to simulate DDR3 interface on PCB.

What current are you carrying?
How many connections do you need for power?

The power to components on the PCB can be connected via PCB tracks, or also by using plane. How does one know if PCB track can be used or must always use a PCB plane to deliver the power?
