VHDL for Avionics: Writing DO-254 Code Without Falling into the Traps

Why “different” VHDL? In avionics, VHDL code doesn’t need to be elegant: it needs to be predictable, verifiable and defensible in front of an auditor. Under DO-254 (ED-80) and AMC 20-152A, the authority expects you to show that the hardware does exactly what the requirements say, and nothing more. In practice, most certification headaches I’ve seen don’t come from a badly designed algorithm. They come from coding details: a latch inferred by an incomplete combinational process, an asynchronous reset released at the wrong moment, a signal crossing two clock domains through…

Why ARINC 429 Still Matters in Modern Aerospace FPGA Designs

Despite the arrival of newer communication standards in aerospace systems, ARINC 429 remains one of the most widely used avionics buses in both civil and military aircraft. From flight management systems to navigation equipment, cockpit displays, sensors, and mission computers, ARINC 429 continues to be deeply integrated into airborne electronic architectures. This is exactly why I recently developed a new ARINC 429 IP core in VHDL for FPGA-based systems. The objective was not simply to create another protocol interface, but to design a flexible and scalable communication block capable of fitting…
