A specialist firm providing one-stop circuit design, FPGA RTL design, PCB design, and embedded software development, from requirements definition through mass production.
Since first opening as a sole proprietorship, one thing has stayed constant: mutual trust and mutual respect. There is naturally a difference in position between client and vendor, but that has never meant a one-way relationship to us. We do our best to meet our clients' requests, while also striving to understand the background and constraints behind them — engaging in technical dialogue as true technical partners.
In 2026, building on more than ten years of track record and trust as the sole proprietorship Asena, we launched a fresh start as Asena Engineering Inc. We chose to incorporate because we wanted to offer a structure that lets more clients work with us with confidence.
Our strength is being able to handle the entire development process — circuit design, FPGA (RTL) design, PCB design, and embedded software — as a single, seamless flow. Without the information loss that comes from splitting work across separate vendors, we keep communication and coordination costs down, enabling cost-effective proposals and faster development. In recent years we have also been implementing local AI on small CPUs, expanding into new areas as the technology landscape evolves.
Going forward, we want to keep engaging sincerely with every single request, while valuing every new client and partner company we get to work alongside. Whatever your technical question, please feel free to reach out.
Before we are client and vendor, we are partners facing the same challenge of building something well. We build trust through dialogue as equals, not a one-way engagement.
Circuit, FPGA, PCB, and software — the entire process handled consistently. No losses from splitting work across vendors, combining agility with price competitiveness.
From implementing local AI on small CPUs onward, we actively pursue new technical territory beyond conventional boundaries, continually expanding the value we can offer our clients.
We specialize in both analog and digital circuit design, supporting everything from requirements definition through simulation-based evaluation as a single continuous process. We place particular emphasis on designs that balance reliability and manufacturability, while also accounting for cost and parts availability.
We place the highest priority on deeply understanding the intent of the circuit design and faithfully reflecting that design philosophy in the artwork. This minimizes discrepancies between circuit and layout, preventing post-assembly issues and performance degradation. We optimize signal routing, power distribution, and component placement to raise the completeness of the overall system.
We perform RTL design in Verilog HDL / VHDL, handling everything from hardware implementation of algorithms to interface control circuit design and verification, as a single continuous process. We are particularly strong in optimizing control logic, achieving efficient and stable implementations within limited FPGA resources. Converting C-language algorithms into RTL is a core strength, balancing computational precision against hardware resource trade-offs.
We develop optimal software with a thorough understanding of the underlying hardware characteristics. Integrating hardware and software development is a core strength, covering everything from bare-metal microcontrollers to embedded Linux and Windows desktop applications.
Working with trusted manufacturing partners, we support everything from prototyping the designed PCB through small and mid-volume production. Having the same team involved from design through production ensures consistent quality and rapid issue resolution.
