Architecture & Chip Designer

The Architecture & Chip Designer combines AI-assisted copilot design, interactive CAD visualization, and logical graph exploration.

Design Copilot (AI Synthesis)

The Design Copilot allows you to design chips using natural language instructions.

  1. Go to the Design Copilot screen.

  2. In the chat interface, type a prompt describing your target chip (for example, “Design a 5-qubit linear transmon processor with 7.0 GHz readout resonators”).

  3. (Optional) Select one of the quick suggestions: * 5-Qubit Linear: Meander chain with nearest-neighbor coupling. * 16-Qubit Heavy-Hex: Error-correction topology. * 64-Qubit Surface Code: 8x8 cryo grid. * 9-Qubit Ring: Closed-loop coherence pocket layout.

  4. Click Send to let the AI design the processor layout.

What you just did: The backend AI parsed your requirements, calculated physical dimensions, assigned non-overlapping frequencies, and synthesized a complete layout.

CAD & Physics Visualization Panels

After a design is generated or loaded, you can view it through several tabs:

  • Chip CAD View (ChipView): - Displays the physical layouts on the substrate. - Toggle layers on and off to focus on details:

    • Pockets: The main qubit capacitors.

    • Meanders: Readout resonators.

    • Grid: Visual alignment grid.

    • Labels: Component identifiers.

  • Frequency Plan View: - Displays a spectrum chart of your qubits and resonators. - Lists the target operating frequency for each qubit and read-out resonator in a table to ensure there are no frequency overlaps.

  • Code View: - Displays the automatically generated Qiskit Metal Python code. - You can copy this code or download it to run locally on your machine.

What this means: These views let you inspect the physical structure, frequency distribution, and code definitions of your chip layout.

Architecture Explorer

The Architecture Explorer provides a graph representation of the processor layout.

  1. Open the Architecture Explorer screen.

  2. The main area displays the qubits as nodes connected by couplers (edges).

  3. Toggle between view modes: * Logical Mode: Shows logical qubits as nodes labeled with their type (Transmon, Fluxonium, Xmon, etc.) and physical specs (coherence time, gate fidelity, control lines). * Physical Mode: Shows a representation of the physical GDS layers including coupling pads, Josephson junctions, and pocket structures.

  4. Click on any node or coupler to inspect its detailed physics parameters in the side drawer.

What you just did: You navigated your chip design as an interactive circuit schematic, analyzing how signals flow between physical qubits.
