IP building blocks

Digital Core IP for integration in ASIC and FPGA products

In the 25 years since TTTech’s foundation, our technology has evolved, transformed, and been adapted for several fields, including aerospace, automotive, off-highway, industrial, and energy.

Along the way we have developed reliable IP building blocks that work under harsh conditions and in safety-critical environments in a variety of industries. With our expertise, experience, and customer-centric approach we can make sure that they will work for you, too.

Safety first

Safety and determinism are two of the elements that connects all our IP building blocks. Our customers work in fields where system failure is never an option: from human space flight to autonomous mobility.  Since its foundation, TTTech has been a pioneer in deterministic networking system design and our focus on safety and determinism has remained a constant in a dynamic industrial environment.

Full customization with an eye on the cost

Our tried and tested IP building blocks mean that you do not have to reinvent the wheel, but you can, if you want to. You can use our IP as is, add a third- party IP, or we can work out new capabilities together, according to your wishes. At TTTech, we are fully vendor neutral and will always try to find a joint solution for the specific use case you have in mind. This approach gives you maximum, cost-effective service and a faster time-to-market.

Cross-industry expertise, certification optional

At TTTech, we have started out in the toughest and most safety-critical market there is: aerospace. Our IP has since been adapted to automotive, industrial automation and energy, ensuring aerospace safety, but at the cost of the specific market. We continue to break into new industries as we speak, and we can help you to do the same. Our IP building blocks are fully certifiable but can also serve as modular stepping stones to upgrade an existing IP to a certifiable level.

TTTech Development Experience / Use Cases

Our Automotive TSN Switch IP is used by several ASIC/ASSP vendors. Among them a Tier 1 ASSP supplier using our IP in 2 generations of his 10 port Automotive GbE TSN Switch. Together both generations have been shipped and deployed in several cars with ethernet and TSN based in-vehicle networks more than 16 million times.

As part of a large zFAS OEM project, TTTech Chip developed a SoC based FPGA integrating a 5-port deterministic Ethernet switch interconnecting CPUs from various vendors (Intel Cyclone SoC ARM Cores, NVIDIA K1 Tegra, Mobileye and Infineon) through various interfaces (PCIe, RGMII, RMII) to ensure reliable ethernet communication of sensor data for performing sensor fusion applications. Additionally, TTTech Chip implemented a LIN controller to obtain sensor data from US sensors. The solution was enrolled as part of the zFAS ECU by the major OEM and shipped in more than 1 million cars. As part of this project TTTEch developed a logging and replay solution for the ECU itself, allowing ECU testing in real traffic condition logging all the sensor and control data coming from/to the ECU with later replay capabilities for debugging. A~10Gbps data stream can so be logged and replayed including data from 7 HD cameras.

As part of a scalable Distributed Control System developed for Vestas, TTTech did a TTE based Switch on FPGA. This system is used in several or Vestas 2, 4 and 6 Megawatt turbines, shipped more than 6.000 times.

Three aerospace products with TTTech's chip IP

As part of its Space/Aerospace System Solutions, TTTech developed several ASICs hosting TTP based controllers and TTE based network controllers. These chips accumulated more than 1 billion flight hours.
