Seb builds a block diagram of your hardware from files you’ve already uploaded, so you can see the whole system — subsystems, components, and the buses wiring them together — at a glance.
Where: Platform → System page (/system).
The System page — a hardware block diagram with components, buses, and a bus filter

​
What you need

The diagram is generated from your hardware context:
  • BOM or schematic — at least one is required. Without either, the page points you to the Context page to upload one.
  • Datasheets and requirements — optional, used to infer connections the schematic doesn’t spell out.

​
Generate it

Press Generate diagram. Generation runs in the background — it can take a couple of minutes — and the diagram appears when it’s ready. A model picker lets you choose which model builds it (defaults to Claude Sonnet). Hit Regenerate from the toolbar whenever your hardware changes.

​
Read the diagram

  • Blocks are components, colored by role — controller, sensor, actuator, comms, power, connector.
  • Edges are connections, labeled with the bus or protocol (CAN, ARINC 429, SPI, I²C, UART, Ethernet, power…) and direction.
  • Solid vs. dashed edges show confidence: a solid line is grounded in your schematic, netlist, or ICD; a dashed line is inferred from datasheets or requirements — treat it as a suggestion to verify.

​
Explore

  • Click a block to highlight it and everything wired to it.
  • Subsystem rail (right) groups blocks by function — click a subsystem to isolate it, or expand it to read its description and component list.
  • Bus filter — click a protocol chip (e.g. CAN) to show only that bus.
  • Data-flow toggle animates signals travelling along every edge at once, so you can watch the full data flow move through the system end to end.
  • Copy Mermaid exports the diagram source for use elsewhere.
The diagram is read-only — to change it, update your BOM or schematic and regenerate.
