Energy infrastructure hardware,
developed with engineers in control

Energy equipment runs on custom digital logic.

Energy equipment depends on electronics to measure conditions, convert power, communicate, and respond to faults. For engineers developing custom digital logic, a small change can reach far beyond one module: another measurement channel may affect shared types, interfaces, diagnostics, and the testbench.

Sigasi Visual HDL brings deterministic semantic analysis into that everyday work. Its workspace connects VHDL, Verilog, and SystemVerilog source with configured libraries and dependencies so engineers can investigate the project while they write and review RTL.

Digital engineering across the energy system

Programmable logic has roles in grid measurement, protection equipment, power-quality monitoring, and power conversion. AMD  identifies merging units and protection devices among its grid applications. Imperix  demonstrates a grid-tied inverter whose control algorithm runs entirely in an FPGA, with a CPU still handling configuration and monitoring tasks.

The wider semiconductor mix also includes analog measurement ICs, processors, battery-monitoring devices, and power semiconductors. Sigasi serves the teams creating and maintaining HDL within that mix; the appropriate hardware architecture depends on the product.

Understand the project before making the change

An interface change may involve internal RTL, supplier IP, generated sources, and vendor libraries. Sigasi helps engineers navigate declarations, references, hierarchy, and dependencies. Supported diagrams provide additional ways to inspect design structure and state machines alongside the source. That context helps a developer investigate unfamiliar logic and gives reviewers a shared implementation to discuss. It is particularly useful when an established design gains new channels or is adapted for another product variant.

Investigate issues while the work is still in progress

Sigasi provides semantic diagnostics and configurable linting in the editor. Engineers can identify supported language and coding-rule issues before they interrupt downstream work. The repair still requires judgment. An unresolved reference may come from a missing package or library mapping rather than incorrect RTL. Investigating the configured project helps engineers address the cause without rewriting valid source.

Preserve implementation knowledge for the next release

Versioned project definitions and shared settings help a team reconstruct the development baseline. Source-derived documentation can capture interfaces, comments, and design structure when regenerated from the relevant source revision. Licensed CLI workflows can repeat supported checks and documentation generation in automation. Where AI agents are approved, Sigasi’s MCP tools provide diagnostics, project context, symbol searches, and formatting while engineers review the proposed changes. The current MCP server requires an open configured project in the extension.

Prepare RTL for the wider engineering process

Sigasi works alongside FPGA vendor and ASIC implementation tools. Simulation, formal verification, timing analysis, control-system validation, and hardware testing retain their respective roles. A clean semantic report does not prove converter stability, protection performance, or compliance with an energy standard.
