# Physics Constraints

- [Overview](https://docs.quilter.ai/physics-constraints/overview.md): Explanation of how Quilter identifies, categorizes, and manages physics constraints during Circuit Comprehension, including automatic detection and manual specification.
- [Power Nets](https://docs.quilter.ai/physics-constraints/power-nets.md): Explanation of Quilter’s Power Net constraint, including automatic detection criteria, recommended naming conventions, default current values, and IPC-based validation methods.
- [Single-ended Impedance Control](https://docs.quilter.ai/physics-constraints/single-ended-impedance-control.md): Details on specifying and validating single-ended impedance-controlled nets, including supported impedances and calculation methods.
- [Differential Pairs](https://docs.quilter.ai/physics-constraints/differential-pairs.md): Instructions on defining differential pair constraints, including detection rules, limitations, supported impedances, and required fields.
- [Timing-sensitive Signals](https://docs.quilter.ai/physics-constraints/timing-sensitive-signals.md)
- [Bypass Capacitors](https://docs.quilter.ai/physics-constraints/bypass-capacitors.md): Guidelines for setting bypass capacitor constraints, including automatic detection criteria, recommended schematic practices, and required configuration details.
- [Crystal Oscillators](https://docs.quilter.ai/physics-constraints/crystal-oscillators.md): Instructions for defining crystal oscillator constraints, covering detection criteria, configuration fields, and current limitations.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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, and the optional `goal` query parameter:

```
GET https://docs.quilter.ai/physics-constraints.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
