AI Copilot

Use Copilot to review a design, investigate a circuit block, prepare schematic changes, and explain simulation results. Copilot shows proposed changes for your review before they are applied.

Review before applying

Ask Copilot, review its findings, inspect every proposed change, and then choose whether to apply, revise, or discard it. After applying a change, run the relevant deterministic check again.

Image — Review and apply a Copilot proposal

Image needed

Capture a real proposal with Apply and Discard visible beside the affected board or schematic context. The image should make clear that nothing changes before the user approves it. Suggested size: 1300 × 760 px.

Ask a focused question

  1. Open your project and the relevant schematic.
  2. Open the Copilot panel.
  3. Describe the circuit section and what you want checked.
  4. Review the components, nets, and warnings mentioned in the response.
  5. If changes are proposed, inspect the preview before selecting Apply.
  6. Verify accepted changes with ERC, DFM, or simulation.

Good questions are specific:

  • “Review the 3.3 V regulator for missing protection and decoupling.”
  • “Check whether the USB connector pins and protection parts are connected correctly.”
  • “Explain why VOUT fails its ripple check after startup.”

Work with circuit blocks

Copilot can group related parts into circuit blocks such as power, protection, connector, oscillator, or logic sections. Use these blocks to focus a review or simulation on one part of a large schematic.

When a proposed block can be placed on the canvas:

  1. Review the parts and connections in the block card.
  2. Drag the card to the schematic.
  3. Check the placement and wire preview.
  4. Place the block.
  5. Review every connection before continuing.

Create a symbol or footprint from a datasheet

When Component Review reports Not in Pool, use AI Gen to create a symbol and footprint from a standard template or a manufacturer datasheet. Follow the complete AI Component Generator guideline before using the result in a board.

Before accepting the generated library item, verify:

  • manufacturer and exact part number;
  • package name and pin count;
  • pin numbers, names, and electrical types;
  • footprint pitch, pad dimensions, drill sizes, and orientation;
  • the assigned simulation model, when required.

Use Manage on the component card to inspect and correct the generated symbol and footprint before placement.

Warning

Always compare generated library data with the manufacturer's recommended land pattern and pin table. A visually correct symbol does not guarantee a correct footprint or pin mapping.

Ask about a simulation result

Open the Simulation Workbench AI tab or select Ask why beside a failed testbench check.

Include the signal and expected behavior in your question. For example:

Explain why VOUT fails the ripple limit after settling. Use the current testbench and measurement.

Copilot can help interpret the result, but it does not decide the acceptable limit. Enter limits from your product requirement or datasheet in the testbench.

Use Copilot safely

  • Review every proposed edit before applying it.
  • Check component ratings and pin mappings against the datasheet.
  • Run the appropriate verification after each accepted change.
  • Ask about one sheet, block, component, or signal at a time.
  • Treat Copilot's response as design assistance, not final approval.
