OpenChippy: digital waveforms

Silent, normal-speed recording of the real OpenChippy desktop application.
The prepared XOR circuit contains four NAND2 blocks and 16 MOS transistors.
The capture is trimmed after the final inspection; it has no accelerated section.

0:00–0:02.5 — The waveform workspace is open. The settings show a 100 ns
simulation length, a 10 ns clock period, and input changes every 20 ns.

0:02.5–0:05.5 — Click Run waveform. The display shows input A, input B, and
output XOR. Each input combination produces the expected XOR behavior:
the output is high when exactly one input is high.

0:05.5–0:08.5 — Click the waveform chart to position its vertical time cursor.
The labels beside the signals show their values at that instant.

0:08.5–0:12 — Click the plus button to zoom into the timeline, then click Fit
to restore the full 100 ns view.

0:12–0:16.5 — Enter Inputs as the group name. Select A and B, then click Create
bus. The new two-bit bus displays the pair of input states in hexadecimal.

0:16.5–0:19 — Expand the bus to display both member traces underneath it.

0:19–0:21.5 — Switch the bus radix from hexadecimal to binary.

0:21.5–0:27 — Move the cursor to approximately 38.747 ns. Input A is LOW,
input B is HIGH, and the XOR output is HIGH. The bus reads 0b01. The screen
shows the binary bus, A, B, and XOR as four lanes.

Captured October 19, 2026, on Apple Silicon macOS with an Apple M6 CPU.
Local OpenChippy release bundle reports version 0.1.0-alpha.1, using the
built-in OpenChippy EDU CMOS technology. Recording: 1600 × 900. The tool's
digital propagation estimates are educational models. There is no audio track.
