London electronics technology company Circuit Mind has announced $25 million in financing and launched an AI-assisted verification application designed to detect electronic circuit errors before prototype boards are manufactured.

The financing includes an $18.5 million Series A led by Norwest and a previously undisclosed seed investment led by Third Prime. Circuit Mind says the announcement brings its cumulative funding to $33.4 million, supporting further software development, recruitment and the establishment of a US headquarters.

Its new Agentic Verification Engine, known as AVE, examines electronic schematics against component datasheets, application notes and an organisation’s own design standards. The application is intended to identify problems that can otherwise emerge during manual review or after physical boards have been produced.

Circuit Mind’s platform already provides automated design generation through its ACE application, while AVE extends the software into verification. The company combines AI agents with structured component information, engineering calculations and customer-specific rules rather than relying entirely on general-purpose language models.

Electronic design involves more than generating diagrams

Developing electronic hardware requires engineers to select components and establish the electrical connections between them while satisfying requirements for performance, power consumption, cost, dimensions and manufacturability.

A schematic records those connections, but the engineering work behind it includes numerous calculations and decisions. Components must operate within their specified electrical limits, interfaces must be compatible and supporting circuitry must satisfy the requirements set out by manufacturers.

Even apparently minor component changes can affect the surrounding circuit. Replacing a device because of price or availability may require adjustments to power supplies, signal levels, operating frequencies or supporting components.

Manufacturers provide much of the relevant information through datasheets and application notes, which can be lengthy and organised differently across suppliers. Engineering teams must interpret those documents alongside their own standards, component preferences and experience from previous projects.

Circuit Mind’s ACE application accepts a hardware architecture expressed as a block diagram and generates candidate schematics, bills of materials and supporting analyses. It uses physics-based calculations and component models to compare alternative designs against priorities such as size, power consumption and parts availability.

The software integrates with electronic computer-aided design systems, component libraries and product lifecycle management tools. That connection is important because engineering teams need outputs that can be incorporated into existing design records and subsequent manufacturing processes.

AVE checks designs before manufacture

The new verification application examines completed schematics, including designs created manually in established engineering software. Different AI agents analyse component documentation, electrical connections and design rules before reporting potential problems.

Some agents examine operating voltages, pin assignments and other component constraints. Others trace connections and buses across the circuit to determine whether the arrangement is consistent with the available documentation.

Circuit Mind says AVE also performs an internal quality-assurance review of its findings before presenting them to engineers. This is intended to reduce the number of unsupported warnings and concentrate attention on problems requiring investigation.

The application addresses a costly point in electronics development. Discovering an error after a printed circuit board has been manufactured can require another design iteration, component procurement, assembly and physical testing.

Where specialist parts have long lead times, a revision may delay an entire product programme. The consequences can extend beyond the engineering team to manufacturing schedules, supplier commitments and planned customer deliveries.

Automated checking could reduce the time engineers spend reviewing repetitive requirements, although the results will depend on the completeness of the component data and the software’s ability to distinguish genuine design errors from acceptable engineering choices.

A schematic can satisfy documented electrical constraints while still encountering problems during physical operation. Board layout, electromagnetic compatibility, heat dissipation, manufacturing variation and signal integrity can all require separate analysis and testing.

AVE therefore complements rather than replaces the verification processes needed before hardware is released for production. Engineers remain responsible for assessing reported issues and ensuring that the design satisfies its complete operating requirements.

Customer evaluations provide an early measure

Circuit Mind says organisations using its platform include Emerson and Schneider Electric, with reported reductions in engineering effort for selected design activities.

Schneider Electric has described early evaluations suggesting that AI-assisted architecture exploration could reduce the time required for that particular activity by more than 90%. The company also highlights the ability to compare alternative designs while incorporating its own engineering standards.

The result concerns architecture exploration, not necessarily the full duration of developing, validating and manufacturing a finished electronic product. Other stages may still require substantial manual investigation and physical testing.

Circuit Mind also cites a case study involving engineers at Los Alamos National Laboratory, in which a design completed using its software reportedly took four hours rather than an estimated two weeks through the comparison process.

That example illustrates the potential reduction in effort for a particular task, but it does not establish equivalent savings across all projects. The commercial benefit will depend on design complexity, the availability of existing component models and the amount of subsequent checking required.

The company separately reports that customers have achieved reductions in bill-of-materials costs of approximately 25% in some applications. Optimising component selection can reduce expenditure, although those decisions must also account for reliability, availability and qualification requirements.

Funding supports expansion across engineering workflows

Circuit Mind plans to extend its platform beyond schematic generation and verification into further parts of the design process, including analysis, reporting, testing and firmware-related work.

The company’s investor group includes Norwest, Third Prime, Differential, Blackhorn and Lightscape VC. Norwest general partner Dave Zilberman will join Circuit Mind’s board following the Series A investment.

Additional funding will support sales, engineering and customer support recruitment, alongside a proposed US headquarters intended to expand its presence in North America.

The commercial opportunity lies in integrating automation into engineering processes where correctness depends on explicit physical constraints. AI can help interpret extensive documentation and coordinate analysis, while deterministic calculations and structured component models provide a basis for checking its outputs.

That approach differs from applying a conversational model to a hardware design without access to the electrical requirements governing its components. Plausible-looking schematics are insufficient when even a single incorrectly connected device can prevent a product from operating.

AVE is being offered through Circuit Mind’s website, with engineering teams able to request access or arrange a demonstration. Its launch adds a verification function to a platform already used for design generation, while the new financing provides resources for extending those capabilities through the electronics development process.
