In the fast-paced world of ASIC and AMS layout design, creating a layout that is simply LVS and DRC clean is not enough. Before a design can move to the physical design (PD) team or be released to the customer, a series of Sanity Checks and Quality Assurance (QA) checks must be performed.
These checks act as a safety net, ensuring that designs are not only functional but also robust, manufacturable, and integration-ready. In this blog, we’ll explore the significance of these checks, why they matter, and how they shape the success of complex analog and mixed-signal (AMS) designs.
Sanity checks are the first layer of validation after completing LVS and DRC. They confirm whether the design meets fundamental expectations before moving forward.
Key considerations include:
These checks help engineers detect critical mistakes early, preventing costly rework during final verification.
While sanity checks catch basic issues, QA checks dive deeper. They evaluate whether the layout meets customer standards, IP release criteria, and integration quality.
Key QA Checks include:

The transition from sanity to QA checks ensures a holistic design sign-off process. Together, they:
Moreover, engineers who master these checks contribute to higher productivity, reduced re-spin risk, and better collaboration between layout and verification teams.
At Semionics, we emphasize that mastering sanity checks and QA checks is a vital skill for every AMS layout engineer. These checks go beyond design rules—they represent the discipline and precision required in semiconductor design.
Our dedicated course, “ASIC – AMS Layout (Sanity Checks + QA Checks)”, provides a structured learning path for:
In essence, sanity checks validate the basics while QA checks ensure design excellence. Together, they form the backbone of reliable ASIC and AMS layout delivery.
Engineers who invest time in learning these practices stand out in the competitive VLSI industry. With Semionics Academy, you gain access to practical workflows, industry insights, and expert-led sessions designed to make you job-ready and project-ready.
