EMBEDDED SYSTEM

Manufacturing-Integrated Embedded System Development Without Separating Design and Mass Production

We flexibly support requests ranging from prototype development and design-only projects to small-lot and single-unit prototypes. Depending on your development phase and objectives, consultation can begin from any required process.
By addressing the separation between design and mass production as a key challenge, we adopt a manufacturing-integrated development approach—incorporating production, inspection, and reliability considerations from the earliest design stages.

SOFTWARE DEVELOPMENT /
HARDWARE DEVELOPMENT ABOUT

Embedded development that doesn’t just “work,” but truly succeeds. With an integrated software and hardware approach, we work alongside you from requirement definition through design—always with mass production in mind.

In addition to digital design such as CPUs and FPGAs, we also support analog circuit design including power supplies, analog front ends, and various interfaces. Leveraging the expertise cultivated through our power supply and semiconductor packaging businesses, we deliver designs focused on stable operation and high reliability, with mass production in mind.

Development Flow

We adopt a collaborative development process in which hardware and software are developed in parallel. By ensuring close coordination between both from the design stage, we reduce development time and effort while minimizing specification mismatches and rework risks.

Embedded Control Systems

Control Software Design for Microcontroller-Based Systems

We design software to control electronic boards equipped with microcontrollers, various types of memory, communications (wired / Wi-Fi), analog circuits, sensors, and more.
Design and Evaluation with EMC and Environmental Testing in Mind

From design that considers EMI/EMS and operating temperature conditions to support for evaluation including noise testing, temperature cycling, electrostatic discharge, and vibration testing.
Migration of Legacy Systems to Modern Platforms

We update boards and microcontrollers that include discontinued components to modern alternatives. When replacing microcontrollers, we also support software modification as well as functional and performance improvements.
PC / Tablet Software Development for Embedded Systems

We develop PC and tablet applications used to operate and control embedded devices, as well as software that converts acquired data into tables, graphs, and analytical formats.

FPGA Design & Simulation Verification

RTL Design (Logic Circuit Design)

Logical circuits are designed using hardware description languages.We support VHDL and Verilog HDL.
Logic Verification by Simulation

Operation is verified using dedicated simulators, allowing bugs to be identified and corrected at the design stage.

Test Systems (Test Automation / Improved Maintainability)

Electrical Characteristic Test System Development for Mass-Production Products

From standard specifications to fully customized requirements, we design and build optimal electrical characteristic test systems, including both hardware and software development.
