2. Placing Decoupling Capacitors:
a. You can use the place icon in the toolbar to add decoupling capacitors near each IC power pin
b. Place a combination of 0.01µF, 0.1µF, and 10µF capacitors for broad frequency coverage
c. In Presto PCB Editor go to ECO > Quickplace Components for automatic placement of capacitors near their chips if
organized by room
Placing capacitors by room makes it easier to place them right next to their respective chip pins, like what is shown in the
image below.
