June 22, 2026 /SemiMedia/ — Renesas Electronics said a subsidiary has completed the acquisition of Pictorus, an Oakland, California-based software developer, as the company expands its Renesas 365 electronics system development platform.

Through the acquisition, Renesas gains a cloud-based behavioral modeling platform designed to accelerate embedded system development. The technology is intended to move engineers beyond fragmented point tools by providing a connected environment for model-based system design.

Renesas said Pictorus will enhance Renesas 365 by allowing engineers to visually design, express and simulate system behavior and intent. The company expects the added capability to shorten application development cycles and support digital continuity from system modeling to software implementation and device deployment.

The deal comes as automotive, robotics and industrial equipment markets increasingly shift toward software-defined systems. In these sectors, early-stage validation, rapid prototyping and faster development cycles are becoming important competitive factors.

Pictorus allows engineers to define device behavior by drawing block diagrams in a web browser. The platform can then convert those diagrams into executable embedded software, generating memory-safe Rust code while supporting interoperability with C/C++ and Python.

Renesas said the approach can make embedded development faster and more accessible by helping engineers evaluate system behavior, design constraints and device choices earlier in the development process.

Leigh Gawne, Renesas’ Vice President of R&D and Digital Industries, Software & Digitalization, said Pictorus adds behavioral modeling and simulation to Renesas 365’s existing architectural modeling capabilities. He said the technology will support rapid virtual prototyping and code generation, enabling faster exploration and evaluation.

Pictorus was founded by engineers with experience in vehicle software development for demanding environments. The company focuses on model-based design, rapid iteration, debugging, deployment and memory-safe code generation for production-grade embedded systems.

Pictorus founder and Chief Executive Officer Chris Sullivan said embedded firmware development still requires engineers to bridge too many gaps between hardware, software, simulation and deployment. He said joining Renesas aligns with the company’s goal of building a more cohesive development workflow.
