Enterprise System Architecture

[!NOTE] This page is for Synth EE contributors and operators who need to understand the synth-ee codebase. End users of Synth Enterprise Edition do not need this information.

The synth-ee workspace is a closed-source Cargo workspace that depends on pinned revisions of the open-source synth crates and adds proprietary extensions on top.

Workspace Structure

synth-ee/
├── crates/
│   ├── synth-enterprise-ebm/   # Enterprise Board Management
│   └── synth-enterprise-wm/    # Worker Management
├── saas/                        # Phoenix LiveView web application (Elixir 1.17+) with SQLite via Ecto, Tailwind CSS, and DaisyUI
└── synth-agent-worker/          # Background worker binary

Open-Source Dependency

synth-ee pins the open-source synth crates by Git revision in Cargo.toml. For local development and integration testing, a sibling checkout of the open-source repo is used instead:

[patch.crates-io]
synth-ir = { path = "../synth/crates/synth-ir" }
synth-place = { path = "../synth/crates/synth-place" }
# ... etc.

Maintain this sibling layout:

workspace/
├── synth/        # open-source repo (github.com/absmach/synth)
└── synth-ee/     # this repo

Enterprise Crates

synth-enterprise-ebm — Enterprise Board Management

Adds multi-board interconnect solving and high-speed differential pair constraints not present in the community edition. Consumes synth-ir::DesignIR and augments it with inter-board net references.

synth-enterprise-wm — Worker Management

Implements the task queue protocol used by synth-agent-worker. Handles job dispatch, heartbeat tracking, worker node autoscaling signals, and result aggregation.
