Developing a custom ASIC is one of the most important decisions a hardware company can make. A well-designed ASIC can reduce power consumption, improve performance, lower unit cost at volume, protect intellectual property, and create a product advantage that is difficult for competitors to copy.
However, a custom ASIC project also involves many technical and commercial decisions. You need the right architecture, technology node, IP blocks, design team, foundry access, packaging strategy, test plan, qualification flow, and production supply chain.
AnySilicon helps companies find the right custom ASIC solution providers for their specific project requirements — from early feasibility studies to full turnkey ASIC development and volume production.
Custom ASIC solutions are services and technologies used to develop an application-specific integrated circuit for a particular product, system, or market. Unlike standard off-the-shelf chips, an ASIC is designed for a defined function and optimized for your own performance, power, area, cost, security, and reliability requirements.
A custom ASIC solution may include:
For many companies, the biggest challenge is not deciding whether an ASIC is technically possible. The real challenge is finding the right ASIC partner for the project size, budget, technology, schedule, and production volume.
A custom ASIC usually makes sense when a standard component, FPGA, microcontroller, or discrete solution can no longer meet the product requirements.
Typical reasons to develop a custom ASIC include:
ASICs can be optimized for a specific workload, which can significantly reduce power consumption compared to general-purpose chips or FPGA-based solutions.
This is especially important for battery-powered products, IoT devices, wearables, medical devices, industrial sensors, and edge-AI systems.
A custom ASIC can be designed around your exact processing, sensing, communication, or control requirements. This can improve speed, latency, noise performance, signal integrity, or real-time response.
Although ASIC development requires upfront engineering and mask costs, it can reduce the bill of materials when production volumes are high enough.
A custom ASIC can integrate multiple functions into a single chip, replacing several components on the PCB.
ASIC integration can reduce PCB area, simplify routing, reduce external components, and enable smaller end products.
By moving key functions into a custom chip, companies can make their design harder to copy and create stronger product differentiation.
A custom ASIC can help reduce dependency on standard components that may become obsolete, unavailable, or subject to allocation.
Different ASIC projects require different design expertise. AnySilicon can help you identify suppliers based on your technical requirements.
Analog ASICs are used when the chip must interface with real-world signals such as voltage, current, temperature, pressure, light, sound, magnetic fields, or biological signals.
Common applications include:
Mixed-signal ASICs combine analog and digital functions on the same chip. These are common in industrial, automotive, medical, consumer, and communication products.
Typical blocks may include ADCs, DACs, PLLs, regulators, digital logic, memory, interfaces, and sensor front ends.
Digital ASICs are used for logic-heavy applications where performance, power, or cost cannot be achieved with an FPGA or standard processor.
Applications include:
RF ASICs are used in wireless communication systems and may include RF front ends, transceivers, frequency synthesizers, and mixed-signal communication blocks.
High-voltage ASICs are used in power, automotive, industrial, battery, and actuator applications where the chip must handle higher voltage domains.
A custom ASIC project normally follows a structured development flow.
The first step is to evaluate whether an ASIC makes technical and commercial sense. This includes estimated die size, process technology, package type, NRE cost, unit cost, development time, and expected production volume.
The specification defines the chip’s required functions, performance targets, interfaces, operating conditions, reliability requirements, test strategy, and commercial constraints.
A strong specification reduces the risk of delays, redesigns, and expensive silicon respins.
The architecture phase defines how the ASIC will be built. This may include partitioning between analog and digital blocks, selecting IP, choosing memory, defining power domains, and selecting the right semiconductor process.
The design team develops the circuit and verifies that it meets the specification. For digital ASICs, this may include RTL design, simulation, synthesis, timing analysis, and formal verification. For analog and mixed-signal ASICs, this includes schematic design, simulation, layout, and parasitic extraction.
The chip layout is created and prepared for tape-out. This includes floorplanning, place and route, clock tree synthesis, routing, signoff, DRC, LVS, and other checks depending on the project type.
Once the design is complete, the final database is sent to the foundry for mask generation and wafer fabrication. Some projects start with an MPW shuttle to reduce prototype cost, while others go directly to a full mask set.
After wafer fabrication, the dies are packaged and tested. The test strategy is critical because it affects yield, quality, production cost, and long-term reliability.
For automotive, medical, aerospace, industrial, or high-reliability applications, qualification can be a major part of the project. Once the device is qualified, the ASIC can move into volume production.
One important decision is whether to use a design-only ASIC service provider or a turnkey ASIC solution provider.
A design-only provider focuses mainly on the chip design phase. The customer may still need to manage foundry access, packaging, test, qualification, and production logistics.
This can work well when the customer already has semiconductor experience and wants to control the supply chain directly.
A turnkey ASIC provider manages more of the complete flow, from specification to production delivery. This can reduce coordination risk because the customer has one main partner responsible for the full ASIC development chain.
Turnkey ASIC solutions are often useful for companies that do not have a large internal semiconductor team.
Choosing the right ASIC partner is one of the most important parts of the project. A good partner should match your technology, business model, production volume, and risk profile.

The cost of a custom ASIC depends on many factors. There is no single fixed price because each project has different complexity, process technology, package, verification effort, and production volume.
Main cost drivers include:
A simple ASIC may require a much smaller budget than a complex SoC, high-speed interface chip, automotive ASIC, or advanced-node digital ASIC.
For this reason, it is important to start with a feasibility discussion before requesting a final quotation.
Custom ASICs are used across many industries where performance, power, cost, reliability, or product differentiation matters.
Industrial ASICs are used in automation, motor control, sensors, robotics, power systems, safety equipment, and measurement devices.
Medical ASICs are used in imaging, diagnostics, wearable health devices, implantable devices, monitoring systems, and laboratory equipment.
Automotive ASICs require strong reliability, qualification, and long-term supply support. Applications include sensors, battery systems, motor control, lighting, safety systems, and power electronics.
Consumer ASICs can reduce cost, improve battery life, and enable smaller form factors in high-volume products.
Communication ASICs are used in wired and wireless systems, optical communication, networking, and RF applications.
Aerospace and defense ASICs often require long product lifetimes, controlled supply chains, reliability, and specific qualification requirements.
Finding the right partner for a custom ASIC project can be difficult. The right supplier depends on your specification, technology, budget, production volume, and schedule.

A custom ASIC solution is a semiconductor development service used to create a chip for a specific product or application. It may include design, verification, wafer fabrication, packaging, testing, qualification, and production support.
The timeline depends on complexity, process technology, verification effort, packaging, testing, and qualification. A relatively simple ASIC may take less time, while a complex mixed-signal, automotive, or advanced-node ASIC can require a much longer development cycle.
An FPGA is often better for low-volume products, fast prototyping, or designs that need to be changed after deployment. A custom ASIC is usually better when the product requires lower power, smaller size, higher performance, stronger IP protection, or lower unit cost at volume.
ASIC design usually refers to the chip design work itself. Turnkey ASIC development covers a broader flow, which may include design, foundry access, packaging, testing, qualification, production, and supply chain management.
The cost depends on design complexity, technology node, die size, IP, packaging, testing, and production volume. The best way to estimate the cost is to start with a feasibility review.
