Linting SystemVerilog Testbench Code: Why Style Matters and Where Regex Falls Short

Writing clean, maintainable, and consistent SystemVerilog testbench code is crucial for efficient verification. While functional correctness is the ultimate goal, enforcing coding styles helps improve readability, collaboration, and long-term maintainability. A well-structured codebase also reduces debugging time and ensures better reuse across projects. The Need for Linting and Style Enforcement Linting tools help enforce best practices by catching stylistic and structural violations early. Some fundamental style checks for SystemVerilog testbenches include: Encapsulation : Ensure proper use of class , local , protected , and virtual keywords to promote modularity. Line Length : Keep lines within a readable limit (e.g., 100 characters) to improve readability. Avoid Global Variables : Minimize or eliminate the use of global variables to prevent unintended side effects. Consistent Indentation and Naming : Follow a uniform inde...
