What types of hardware issues can it detect?

It identifies critical RTL design flaws such as unused signals, width mismatches, case statement incompleteness, and unintended latch inference.

Do I need to provide file paths every time?

No, the skill can automatically detect SystemVerilog files (.sv) in your current directory and RTL subfolders if no specific files are provided.

Is this skill specific to a particular FPGA vendor?

No, it uses Verilator which is vendor-neutral and follows IEEE 1800 SystemVerilog standards, making it compatible with any hardware design flow.

What tool does Gateflow Lint use for analysis?

It utilizes Verilator, a high-performance open-source SystemVerilog simulator and linting tool, to perform static analysis on your RTL files.

Can it fix the errors it finds automatically?

While the lint skill itself identifies and explains errors, it is designed to work with the Gateflow orchestrator to trigger refactoring agents that can suggest or apply fixes.

Security & Testing

Lints SystemVerilog code using Verilator to identify design errors, warnings, and performance bottlenecks with structured feedback.

Gateflow Lint is a specialized static analysis tool designed for hardware engineers using Claude Code. It leverages Verilator to perform comprehensive checks on SystemVerilog RTL, categorizing issues into errors and warnings while providing human-readable explanations for common design pitfalls. By generating a machine-parseable result block, it allows the Gateflow orchestrator to automatically trigger refactoring steps, making it an essential component for high-velocity hardware development and verification.
