Simulation Logs

A real-time record of every significant event that occurs while your circuit is running.

What simulation logs track

The log captures events across several categories:

  • Component failures — overheating, overcurrent, voltage breakdown, and reverse breakdown events
  • Warnings — components approaching (but not yet exceeding) their rated limits
  • Voltage events — nodes reaching threshold voltages or crossing zero
  • Current events — current surges, drops, or direction reversals in branches
  • Temperature events — components crossing thermal warning thresholds or cooling back down

How to open the logs

Click Open Logs in the simulation bar (bottom of the canvas). The log panel slides up and stays visible while the simulation runs. You can resize the panel by dragging its top edge.

Log entry anatomy

Each entry contains three parts:

PartDescription
TimestampTime elapsed since simulation start (e.g., 00:04.231)
Event type iconColor-coded icon: ⚠️ warning, 🔴 failure, ℹ️ info
MessageHuman-readable description of the event and the component involved

Hover over any log entry to see a details tooltip with the exact measured value that triggered the event (e.g., Resistor R3 — power: 1.42 W, rated: 1.00 W).

Clicking an entry highlights the corresponding component on the canvas.

Exporting logs

Click Export (↓) in the logs panel header to save the current log as a .txt file. The exported file includes the board name, simulation date/time, and all entries in chronological order.

Clearing logs

Click Clear (🗑) in the logs panel header to remove all entries for the current session. Logs are also cleared automatically when you click Stop (⏹) and start a new simulation run.
