Alp Platform names a set of component versions that we have built and bench-validated together on real modules: the Alp SDK, the tan build CLI, the VS Code extension, and the GD32 and CC3501E bridge firmware. Instead of matching five version numbers by hand, you pin one platform line.

tan platform use 26.11      # newest 26.11.x
tan doctor                  # reports the platform and any off-manifest component

Platform versions are CalVer (YY.M.MICRO); the first line is 26.11. Each component keeps its own SemVer — the platform adds a tested set on top, it never replaces a component version. Every release attaches its platform.yaml manifest; the latest release lists the exact component versions and the validated hardware.

• E1M Standard (E1M-STD-1.0) — open, silicon-agnostic pinout + mechanical envelope for AI-capable Systems-on-Module in two form factors: E1M (35 × 35 mm, 312 pads) and E1M-X (45 × 65 mm, 496 pads). The standard fixes the universe of pads and which signals each may carry; silicon variants — E1M-AEN (Alif Ensemble), E1M-X V2N (Renesas RZ/V2N), E1M-X V2M (RZ/V2N + DEEPX DX-M1) — declare their routed subset in per-variant SoM manifests. Any vendor can ship pin-compatible modules; any product board targets one connector and accepts multiple SoMs.
• Alp SDK — unification C/C++ firmware framework for E1M modules. A single board.yaml drives Zephyr, Yocto, and bare-metal builds across Alif Ensemble, Renesas RZ/V2N and DEEPX DX-M1 silicon — single-OS or heterogeneous (Zephyr + Yocto + bare-metal coexisting on one SoM from one declarative project). Ships with 80 chip drivers, ML inference dispatch (TFLite Micro → Ethos-U / DRP-AI / DEEPX), and runtime hardware identification from the on-module EEPROM manifest.
• tan — the standalone build CLI that turns an Alp SDK project into firmware. One command surface (tan build / validate / doctor / platform / …) reads a board.yaml, plans the build, and produces a Zephyr / Yocto / bare-metal image end-to-end. Prebuilt binaries for Linux, macOS and Windows.
• VS Code extension — schema-aware board.yaml editing and a GUI configurator. It shells the same tan binary, so anything you can do in the editor you can do from the terminal.
• Bridge firmware — the on-module coprocessors: gd32-bridge-firmware (GD32G553 I/O bridge on E1M-X) and cc3501e-bridge-firmware (TI CC3501E Wi-Fi 6 + BLE on E1M-AEN). Wire contracts and host drivers live in the Alp SDK.

• Signex is an open-source, AI-first EDA suite built in Rust with GPU-accelerated rendering and an Altium Designer-quality UI — schematic + PCB editor, 3D viewer, simulation, plugin system. Native file formats (.snxsch, .snxpcb, .snxsym, .snxfpt) are line-diffable in git and ~5× smaller than the equivalent JSON. Migrating from KiCad or Altium? The optional signex-kicad-import companion (GPL-3.0-or-later, distributed independently) converts .kicad_sch / .kicad_pcb / .kicad_pro one-way to Signex's native formats, and signex-altium-import imports Altium Designer schematics, PCBs and libraries.
  • Signex Community (Apache-2.0) — full schematic + PCB editor, 3D viewer, simulation, plugin system. Free forever.
  • Signex Pro (subscription) — adds Signal AI (Claude-powered design copilot), real-time collaboration, and Signex 365 cloud PLM.

You drive one command surface; it fans down to the SDK and out to a firmware image. The VS Code extension is a GUI over the same tan binary — nothing you can do in the editor is off-limits from the terminal.

A board.yaml at the top compiles down through each layer to silicon. Every layer is declarative and swappable — change the SoM, keep your source.

• Alp Platform — the first line, 26.11, is released for E1M-AEN801. The release page is the source of truth for component versions and validated hardware.
• Alp SDK — every chip driver, peripheral wrapper, and example builds clean on native_sim. E1M-X V2N and E1M-AEN801 (Alif Ensemble E8 peripherals + NPU inference) carry silicon evidence; per-claim status is tracked in the SDK's verification ledger. Remaining families are pre-silicon.
• tan — resolves the SDK with zero flags, pins workspaces to a platform line (tan platform use), and ships build-provenance-attested release binaries; the Linux binary is built to a glibc 2.31 floor.
• Signex — see the latest release.
