Flight- and space-critical hardware,
developed with engineers in control

An aerospace RTL project outlives its first implementation.

An aerospace RTL project has a life beyond its first implementation. Engineers change, supplier IP evolves, and hardware moves to new device generations. Years later, another team may need to understand why a block exists and what a change will affect.

Sigasi Visual HDL gives engineers a workspace for that continuing work. Its deterministic semantic analysis connects VHDL, Verilog, and SystemVerilog source files with their configured libraries and dependencies, bringing project context into everyday RTL development.

Catch issues while the design is taking shape

A missing package or unresolved reference should be investigated while the engineer is working on the change. Sigasi provides diagnostics and configurable linting in the editor, helping teams identify supported language and coding-rule issues before they interrupt downstream work. That feedback also helps engineers investigate the cause. A missing dependency may require a project-configuration fix rather than a rewrite of otherwise valid RTL. Resolving the right problem early keeps review attention on the design itself.

Make inherited designs easier to understand

A source tree rarely explains the architecture on its own. Navigation, reference searches, hierarchy views, and diagrams help engineers explore unfamiliar RTL and follow its relationships. State-machine views make supported control structures easier to inspect directly alongside the code. For a team taking over a legacy design or integrating supplier HDL, that means a practical way to investigate the implementation. Source-derived documentation can capture interfaces, comments, and design structure for later review, provided teams regenerate it from the relevant baseline.

Support the assurance process from the front end

Airborne and space programs operate within different assurance frameworks. FAA guidance recognizes DO-254/ED-80  for airborne electronic hardware. European space projects may apply ECSS engineering  and product-assurance  standards for ASICs, FPGAs, and IP cores , tailored to the program.

Sigasi supports disciplined RTL development within those processes. Its configurable checks include mappings to selected best-practice coding guidelines used in DO-254 programs. Those checks help engineers apply coding expectations consistently; they do not establish DO-254 compliance or certify hardware.

Keep your implementation and verification flow

Sigasi works alongside FPGA vendor tools such as Vivado, Quartus Prime, and Libero, and alongside ASIC implementation flows. It concentrates on the HDL project that engineers create and maintain. Simulation, formal verification, synthesis, timing analysis, and hardware testing continue to answer their respective engineering questions. Teams can also use licensed CLI workflows to run supported checks and generate documentation in automation. Consistent results depend on controlling the source baseline, tool version, configuration, and dependencies.

Give AI agents concrete engineering feedback

Where a program permits AI-assisted development, Sigasi can give supported agents access to diagnostics, project context, symbol searches, and HDL formatting through MCP. The current MCP server runs inside the Sigasi extension with the project open.

An agent can use that feedback to revise its changes. Engineers still review the implementation against its requirements, and the design still passes through the program’s verification and assurance activities. A clean diagnostic report is useful feedback, not proof of functional correctness.

Build continuity into RTL development

Aerospace teams need to understand both today’s changes and the design they will inherit tomorrow. Sigasi brings project-aware analysis, navigation, visualization, and documentation into that daily work.
