In VLSI design, maintaining clean, error-free HDL code is essential for successful chip development. One of the most effective ways to ensure code quality is by running lint checks—a static analysis technique that detects potential coding issues before simulation or synthesis. This article provides a practical, step-by-step guide on how to run lint tools, interpret lint…
In VLSI design, ensuring high-quality, error-free RTL code is critical for successful chip development. One essential step in this process is performing a lint check on your HDL code. Linting helps detect potential coding issues early, improving code reliability, readability, and synthesis results. This article explains what lint checking is, why it matters in VLSI design, highlights…

When working with Hardware Description Languages (HDLs) such as Verilog or VHDL, understanding the design flow is crucial for successful digital circuit development. Three fundamental steps in this flow are Compilation, Elaboration, and Simulation. These steps ensure that your HDL code is syntactically correct, logically consistent, and behaves as expected before hardware implementation. In this article, we will…

Post-silicon debug (or post-silicon validation) is one of the important phase of the system design cycle. This is performed to capture the escaped design bugs from the pre-silicon verification phase. The major challenge associated with the post-silicon debug is the very limited observability and controllability inside the chip during the debug. Therefore, a few supporting…
Modern day Syetem-on-Chips are so complex that pre-silicon verification is no more the sufficient step to capture all the design bugs. Even with sophisticated verification process, achieving 100% coverage is difficult. Due to this, few bugs escape from the pre-silicon verification till the actual product on silicon. So, now-a-days industries perform post-silicon validation (commonly known…
Both Verification and Validation checks for the correctness of the design. These design steps try to detect and localize functional bugs in the system. While pre-silicon verification runs the test cases on the software prototypes of the design on the simulator, post-silicon validation is executed on a few initial hardware prototypes of the design on…
