VLSI Design Practice Test

The VLSI Design Practice Test is a free intermediate-level, 20-minute skill test from Science of Apps. It tests VLSI design knowledge used in front-end and physical design roles — CMOS fundamentals and digital logic, RTL design and verification, static timing and low power, and physical design and sign-off — written to IEEE 1800 SystemVerilog, IEEE 1801 UPF and standard digital IC design curricula (MIT 6.374) for 2026. It is a practice test, not a vendor certification. Score 70% or more on its 20 questions to earn a verifiable VLSI Design Readiness certificate (SOA-VLSI). Every question is based on published standards and research — including 6.374 Analysis and Design of Digital Integrated Circuits (MIT OpenCourseWare), IEEE 1800-2023: SystemVerilog Language Reference Manual (IEEE Standards Association), IEEE 1801 Unified Power Format (UPF) for low-power design (IEEE Standards Association) — and each answer is explained with its source.

Yes. Science of Apps has a free VLSI Design Practice Test built on the current exam outline for 2026 and 2027. It covers CMOS and digital logic, RTL design and verification, static timing and low power and physical design and sign-off, scores you instantly and issues a verifiable certificate.

Read the four skill areas on this page, then take the 20-minute test online — no fee, course or sign-up. You see every answer explained when you finish. Score 70% or more and you get a VLSI Design Readiness certificate straight away, on screen, as a PDF and by email, with a credential ID anyone can verify.

Yes. The questions are original scenarios written by Science of Apps, and each one is based on a public source you can read: 6.374 Analysis and Design of Digital Integrated Circuits (MIT OpenCourseWare); IEEE 1800-2023: SystemVerilog Language Reference Manual (IEEE Standards Association); IEEE 1801 Unified Power Format (UPF) for low-power design (IEEE Standards Association). The source is shown under each question and linked in the answer review. Science of Apps doesn't copy questions from other tests.

Four skill areas with five questions each, drawn from a bank of 10 per area so a retake brings new questions: CMOS and Digital Logic (CMOS, Gates and Sequential logic); RTL Design and Verification (Verilog, SystemVerilog and Verification); Static Timing and Low Power (STA, Timing and Low power); Physical Design and Sign-off (Floorplan, CTS, Routing and Sign-off). Every question is an original scenario written to the 2026–2027 standard, with the published source named under it.

RTL design engineer, ASIC verification engineer, Physical design engineer, Static timing analysis engineer and VLSI graduate or intern. It suits anyone who wants a quick, verifiable way to show VLSI Design knowledge in 2026 and 2027, from students and career switchers to experienced professionals.

VLSI tests usually cover CMOS and digital logic basics, RTL coding in Verilog or SystemVerilog, verification, static timing analysis, low-power techniques and physical design steps such as floorplanning, placement, clock tree synthesis and routing.

There is no single owner of a VLSI credential. Employers judge skill through interviews and project work, and EDA vendors and universities offer tool-specific or course certificates, so a practice test like this one helps you prepare for technical interviews.

Yes. The test is online, in English and free everywhere — people take it from India, the US, the UK, Europe, Africa, Latin America and Asia-Pacific. Your certificate is dated with your own local date and can be verified from anywhere at scienceofapps.com/certification/verify/.

20 questions — 5 from each of 4 skill areas — with a 20-minute limit. You need 70% (14 of 20) to pass and 90% for distinction.

We rate it Intermediate: assumes hands-on experience in the role. It has 20 scenario questions — 5 from each of 4 skill areas — and a 20-minute limit. You need 70% (14 of 20) to pass and 90% for distinction.

Nothing. There is no fee to take a test, to receive the certificate, to have it emailed or to verify it, and no sign-up.

On our server, not in your browser. The answers never reach the page until you submit, so a certificate can only be earned by passing. Each certificate gets a unique credential ID stored by Science of Apps.

You see your score for each area and every question with the correct answer and why, with the published source behind it. You can retake after 30 minutes, and the retake draws questions you haven't seen yet.

No. Every certificate is dated, so it always shows when you passed. Retake a test any time for a newer date or a higher score.

Yes. After you pass, Add to LinkedIn opens the Licenses & certifications form with the certificate name, Science of Apps as the issuer, the issue date, your credential ID and the verification link filled in. You can also download it as a PDF or PNG, and it's emailed to you as a PDF.

Every certificate has a credential ID and a QR code. Scanning it, or entering the ID at scienceofapps.com/certification/verify/, shows the holder's name, the certification, the score and the issue date from our records.

No. They are Science of Apps' own assessments of applied skill. They aren't issued by a university or standards body, and they work best alongside a portfolio that shows the skills in real work.
