I had always thought that if an IC is grounded to the ground plane then connecting a decoupling capacitor to VDD on one side and straight to ground plane on other side as shown below is acceptable:
However as I understand this poorly spelled guide from the depths of the internet tells me I was wrong all along and the correct way is to run a trace from the IC ground pin to the capacitor and THEN connect to the ground plane:
I believe I was using d) which is somehow wrong. Can anyone more experienced shed some light on this topic, which one of these is the preferred method? Thank you.
