fpga-led-probe-allocation SKILL.md skillA
fpga-led-probe-allocation from vibeic/vibe-ic is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Codify FPGA LED probe allocation patterns (instantaneous / pulse-stretched / sticky / byte-display) and produce an FPGA-top template with comment-table mapping (LED → signal → expected behaviour per test stage). Use when a fresh agent has to verify a chip on a DE10-Lite-class board with no scope and only the on-board LEDs as visibility, and you want to allocate the LEDs systematically rather than guessing.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# FPGA LED probe allocation ## When to use - The host machine has no oscilloscope / SignalTap on the rig. - The user has a DE10-Lite, DE10-Nano, or similar board with a row of LEDs as the only on-board observability. - A USB webcam (or phone) will be used to capture LED states for before/after diff via `device_camera_capture` / `device_camera_led_diff` (mcp-eda v0.99+). ## The four probe modes Picking the right mode for each signal is the difference between an LED that flashes too fast for a 30 fps webcam to catch and one that holds long enough for diff-capture but doesn't lie about the system state. | Mode | Visible duration | Use when | Pattern | |------|------------------|----------|---------| | **instantaneous** | 1 cycle | signal is steady-state (FSM in IDLE, register holds value) | `assign LED[N] = signal;` | | **pulse-stretched** | ≥ 5 ms | signal is a 1-cycle pulse you want to *see* | `pulse_stretch #(50000) u_st(.clk(clk_50m), .pulse_in(signal), .led_out(LED[N]));` | | **sticky** | latched until reset / next event | signal is a "did this event ever happen?" flag | `always_ff @(posedge clk_50m) if (rst_n & signal) seen_q <= 1; assign LED[N] = seen_q;` | …

How to install
mdr add vibeic/vibe-ic/fpga-led-probe-allocation@sha256:34fc36cfd3c734bbThe line at the top of this page pins the label git:20260803.26669fa, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
