RTL Design with Verilog & SystemVerilog Certification

The RTL Design with Verilog & SystemVerilog Certification is a free advanced-level, 25-minute skill test from Science of Apps. It tests RTL design with Verilog and SystemVerilog — hardware description versus programming, modules, ports and hierarchy, data types including wire, reg, logic and four-state values, blocking versus non-blocking assignment, combinational and sequential always blocks, latch inference and complete sensitivity, synchronous reset and clock domain crossing, finite state machine coding styles, datapath elements such as adders, multipliers, shifters and muxes, memories and inference of block RAM, parameterisation and generate blocks, interfaces, packages and structs, synthesis-friendly coding and the synthesisable subset, static timing analysis with setup, hold and slack, pipelining and retiming, clock gating and low-power design, linting and CDC checking, FPGA versus ASIC flows, and simulation with assertions, coverage and open tools such as Verilator and cocotb — written to IEEE 1800, Accellera, AMD and Intel sources for 2026 and 2027. Score 70% or more on its 25 questions to earn a verifiable RTL Design with Verilog & SystemVerilog certificate (SOA-RDVS). Every question is based on published standards and research — including IEEE 1800-2023: SystemVerilog Language Reference Manual (IEEE Standards Association), Vivado Design Suite User Guide: Synthesis (AMD (Xilinx)), Intel Quartus Prime design recommendations and timing closure (Intel / Altera) — and each answer is explained with its source.

Science of Apps offers a free RTL Design with Verilog & SystemVerilog Certification, written for 2026 and 2027. It tests language fundamentals, designing logic, synthesis, timing and power, verification and quality and systems and practice with 25 original scenario questions in all, each naming its published source; you get an instant score and a verifiable certificate with a credential ID you can add to LinkedIn.

Read the five skill areas on this page, then take the 25-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 RTL Design with Verilog & SystemVerilog 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: IEEE 1800-2023: SystemVerilog Language Reference Manual (IEEE Standards Association); Vivado Design Suite User Guide: Synthesis (AMD (Xilinx)); Intel Quartus Prime design recommendations and timing closure (Intel / Altera); OpenTitan hardware design and verification guides (lowRISC / OpenTitan project); IEEE 1364: Verilog Hardware Description Language (IEEE Standards Association); Universal Verification Methodology (UVM) standard and reference (Accellera Systems Initiative). The source is shown under each question and linked in the answer review. Science of Apps doesn't copy questions from other tests.

Five skill areas with five questions each, drawn from a bank of 10 per area so a retake brings new questions: Language Fundamentals (Modules and types, Assignments and Procedural blocks); Designing Logic (FSMs and control, Datapath and Memories and parameters); Synthesis, Timing and Power (Synthesisable coding, Timing analysis and Power and flows); Verification and Quality (Simulation and assertions, Coverage and Tools and practice); Systems and Practice (Buses and interfaces, Open hardware and Design discipline). Every question is an original scenario written to the 2026–2027 standard, with the published source named under it.

Digital design or RTL engineer, FPGA developer, Computer engineering student, Verification engineer learning design and Embedded systems engineer moving to hardware. It suits students at leading universities, career switchers and experienced professionals who want quick, verifiable proof of RTL Design with Verilog & SystemVerilog knowledge in 2026 and 2027.

Engineering cohorts at IITs, KAIST, NTU Taiwan, TUM, Tsinghua and Georgia Tech are being pulled into chips, energy and space. Passing earns a founder-signed Science of Apps certificate with a credential ID and QR code that recruiters can verify.

Blocking (=) executes immediately in order and suits combinational logic; non-blocking (<=) schedules updates at the end of the time step and is used in clocked always blocks to model flip-flop behaviour correctly.

If a combinational always block does not assign every output on every path, the synthesiser must hold the previous value, which infers a latch; assigning defaults first or using a complete if/else and case avoids it.

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/.

25 questions — 5 from each of 5 skill areas — with a 25-minute limit. You need 70% (18 of 25) to pass and 90% for distinction.

We rate it Advanced: assumes years in the role or deep specialist knowledge. It has 25 scenario questions — 5 from each of 5 skill areas — and a 25-minute limit. You need 70% (18 of 25) 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.
