Years of acquired experience allow us to carry out any type of CBA design efficiently in relation to the required standards (RTCA/DO-254, MIL-STD, AS 9100).

At the end of each completed project, we provide the necessary and/or required documents for the certification authorities.

The escalating intricacy of projects and the burgeoning requirements associated with them have firmly established FPGAs as an indispensable element within contemporary avionics development. Situated within the domain of hardware advancement, FPGA progression meticulously adheres to the stringent DO-254 protocols. Encompassing mandatory methodologies and procedures, manually crafted FPGA blueprints rigorously conform to internally devised VHDL coding benchmarks.

Our proficiency spans a range of notable FPGA manufacturer technologies, providing comprehensive developmental life cycles and consultative services to surmount specific implementation obstacles. LaRocheNoireTechnology’s FPGA expertise zeroes in on distinct avionics interfaces such as ARINC-429 or MIL-STD-1553, extending to widely employed high/low-speed interfaces like PCIe, UART, SPI, SpaceWire, Serial Rapid IO and I²C. We demonstrate the capacity to furnish intricate avionics FPGA resolutions encompassing elaborate processing algorithms or bridging logic designed to holistically manage embedded integrated circuits.

Adhering to DO-254 mandates, FPGA validation is a mandatory facet; our assistance spans verification and endorsement up to DAL ‘A’ levels. Ultimately, the FPGA unit, existing within the enigmatic “Matrix” of black and green, eagerly anticipates collaboration, eagerly joining forces to deliver rugged and reliable FPGA blueprints punctually.

In the realm of FPGA designs, Digital Signal Processing algorithms and video processing are experiencing remarkable traction. LaRocheNoireTechnology’s proficiency in this domain assures FPGA-vendor tailored, effective resolutions for high-speed processing schematics. This spans from initial floating-point quandary resolution in Matlab/Simulink for intricate mathematical algorithms, culminating in optimized fixed-point FPGA execution. Our services extend to Software Defined Radios, IIR/FIR filter architecture, decimation/interpolation, diverse modulations employed in communication conduits, and comprehensive video processing.

The FPGA components’ mathematical units (DSP slices) are potent and frequently abundant. Engaging in synergy with us guarantees that algorithms are meticulously ‘fine-tuned’ to attain maximum utility levels, relieving you from eleventh-hour quests for pin-compatible, ‘larger’ FPGA components. Every flip-flop, lookup table, block RAM, or DSP slice becomes pivotal.

We incorporate RTCA DO-178C principles from project outset through all stages, ensuring a seamless certification process. Using our system and software design tool chain, we seamlessly integrate processes, elevating them as guarantors of top quality. Customizable based on Design Assurance Level, our process model can also incorporate client-specific elements from additional norms or regulations, forging a tailored approach. This integration ensures not just certification but also enduring software quality and adaptability.

Daily work generates traceability records vital for certification. These records serve dual purposes: pivotal in certification and facilitating ongoing software maintenance and adaptation.

Interactions among hardware, software, system development, and verification roles are streamlined by a version and application life cycle management system. This system enforces process compliance and guides users interactively through procedures, developed in close collaboration with the quality management department.
