Analog and digital components are becoming increasingly interdependent, creating complex implementation and maintenance challenges. While you can no longer ignore the need for effective integration, functionally verifying designs takes expertise that the average industry professional lacks. Like many people in your position, you may ask yourself, “I need help with mixed-signal verification, so where should I look?” You have several national and international service providers to choose from, ensuring you can find help regardless of location.
1. ASIC North
For over 25 years, ASIC North has provided world-class services nationwide. It serves the systems engineering, technology and manufacturing sectors, providing custom application-specific integrated circuit (ASIC) and very-large-scale integration (VLSI) chip design and engineering. If you need help with mixed-signal verification, you should look no further.
It will carry your IC system from start to finish in an analog-mixed-signal (AMS) based, top-down design flow. It utilizes a Verilog-A-based, system-level schematic at the start instead of assigning AMS verification simulations toward the tail end of the process. This way, it has more time to pivot if the unexpected occurs, significantly reducing your overall program risk.
If you have critical timing paths that cross the analog and digital boundaries, it leverages a back-annotated standard delay format to conduct special AMS simulations. It extracts the path-relevant analog portions to ensure your design will perform.
You will remain involved throughout the entire process. ASIC North’s customer support is second to none, making it a leader in world-class ASIC and VLSI design services. In a review, IBM’s global commodity manager said they’ve worked with many suppliers over their 36 years, but none have outperformed this one. Its professionalism and dedication are superior.
2. ADVANS Group
ADVANS Group comprises software, electronics, and mechanical engineering companies based in the United States, France and Serbia. AViSTO, MECAGINE and ELSYS are the main three. Their international subsidiaries and stakeholders are also included. The founder established the group in 2000 — today, it has 1,100 employees and 14 locations worldwide.
Its core areas of expertise cover ASIC, intellectual property (IP) core and system on a chip (SoC) design. Its engineers also have experience with integrated circuit (IC) verification, printed circuit board layout, embedded software development, DevOps and quality assurance.
The analog mixed-signal verification services include project planning, functional specification assessment, testing and regression runs. Engineers will define, develop and maintain a verification environment architecture for you to check the functional correctness of the unit under test. They focus on the chip’s analog part, ensuring every module and connection works properly. The test suite has test cases and scripts to validate functionality.
Its digital mixed-signal verification service differs slightly. It still involves project planning, function specification assessment, test suite development and regression runs. However, it also incorporates automation and coverage analysis. It verifies your IP and SoC levels.
3. Cadence Design Systems
Cadence Design Systems has a global presence with locations in 26 countries and over 11,200 team members. Both customers and staff have good things to say about it. For the record, it ranked No. 11 on Fortune’s “100 Best Companies to Work For” list in 2025 and has placed 10 years running.
Its services are just as renowned. It has several mixed-signal offerings to address your implementation and verification challenges. As analog and digital components become increasingly interconnected, it aims to deliver an interoperable, comprehensive solution.
Cadence streamlines workflows to enhance design efficiency, increasing throughput. Its ecosystem of technology, IP and customer support provides the foundation for consistent success. The analog and digital design teams share information to reduce iterations and shorten turnaround times.
The president and CEO of SCALINX — a fabless semiconductor firm — said Cadence’s tools helped with digital and custom in-design flows. Ultimately, they made turnaround times 1.5 times faster and resulted in a 30 percent overall productivity increase.
4. InnoFour
If you run a small or medium-sized entity in Europe or North America, you fit InnoFour’s typical clientele. This Netherlands-based company’s dedicated engineering team serves the electronic design sector. It supplies and develops proven technologies — for instance, its concurrent computational fluid dynamics system reduces simulation time by up to 75 percent.
This organization has several analog mixed-signal verification products. For instance, its Analog FastSPICE Platform is the world’s largest nanometer circuit verification solution for custom digital circuits. Alternatively, you can use Solido Variation Designer for variation-aware design and verification, gaining more comprehensive coverage with fewer simulations.
mPower Analog is worth mentioning if scalability is important to you. This suite of tools lets you power integrity analysis ranging from the smallest blocks to the largest full-chip layouts. You can verify designs before committing to a product run. Symphony Platform does something similar, validating functionality, connectivity and performance at all levels.
In total, there are six mixed-signal verification tools. Various solutions can lower development costs, reduce risk or accelerate time to market. InnoFour claims they can increase productivity by up to 40 times. Each aims to optimize performance without raising development and prototyping expenses.
5. Ignitarium Technology Solutions
In the semiconductor sector, Ignitarium is a leading product engineering services provider. It has partnered or allied with big names like Nvidia, Qualcomm, Intel, Amazon Web Services and Microsoft Cloud to offer you high-quality services.
These professionals have a deep understanding of device mechanics and digital protocols. They also comply with strict quality assurance and process compliance rules across all business aspects. They follow ISO 9001:2015 and ISO/IEC 27001:2022 certifications, demonstrating their commitment to the highest standards.
The managing director and vice president of engineering at LifeSignals said working with the team was “a pleasure,” noting they were professional, skilled and thorough. They provided much-needed help at many of the project’s critical points.
AMS verification involves testing and validating ICs with digital and analog components. The team makes sure they meet performance requirements, functional specifications and reliability standards to ensure design integrity.
The process starts with project planning and model creation based on SPICE simulations before moving to block-level or full-chip test cases. The various top-level verification tasks include layout versus schematic debug and simulations using the AMS flow, but Ignitarium automates some steps to shorten turnaround times.
Which to Choose for Help With Mixed-Signal Verification
Now that you know where you should look for help with mixed-signal verification, you need to understand how to pick the service provider that aligns best with your needs. Some — like ASIC North — provide free quotes, which can streamline the process. Ultimately, cost, turnaround time and methodologies will be your deciding factors.
