Pin Distance

Summary of the Pin Distance PRC, checking pin spacing to ensure short traces, reduced EMI, and improved routing efficiency.

Description

Pin Distance calculates the Euclidian distance between the closest edges of two pins.

Passing Criteria: This check passes is the pin distance falls below a specified tolerance

Reporting Units: CENTIMETERS (cm)

Examples

Passing Message:

Pin distance of 0.13cm within acceptable range (0cm to 1cm)

Failing Message:

Pin distance of 1.11cm outside acceptable range (0cm to 1cm)

Physics Justification

Minimizing the pin distance is important because it:

• Reduces Trace Lengths Shorter traces mean lower parasitic inductance and resistance, which improves signal integrity and power delivery.

• Minimizes Loop Area Smaller loops reduce susceptibility to electromagnetic interference (EMI) and radiated noise.

• Improves Routing Efficiency Compact pin placement contributes to cleaner and more manageable routing, especially in densely designed circuits.
