General Solution
Effective PCB layout involves defining an appropriate stackup, strategically placing components, and routing traces according
to the defined constraints. This approach ensures optimal signal performance, minimizes electromagnetic interference, and
facilitates proper power distribution.
Application in OrCAD X Presto:
1. Define the PCB stackup:
a. Go to Tools > Cross Section
b. We have an 8-layer stackup with dedicated power and ground planes:
i. Top Layer (Signal)
ii. Ground Plane (GND1)
iii. Signal Layer 1 (L1)
iv. Power Plane (POW1)
v. Ground Plane 2 (GND2)
vi. Signal Layer 2 (L2)
vii. Power Plane 2 (POW2)
viii. Bottom Layer (Signal) (BOTTOM)
