# Pin Distance ### 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:** {% hint style="success" %} Pin distance of 0.13cm within acceptable range (0cm to 1cm) {% endhint %} **Failing Message:** {% hint style="danger" %} Pin distance of 1.11cm outside acceptable range (0cm to 1cm) {% endhint %} ### 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. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.quilter.ai/physics-rule-checks-prcs/pin-distance.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
