X2CON
Safety-critical FPGA design does not tolerate shortcuts between the algorithm on the whiteboard and the bitstream in the field. X2CON closes that gap with a Model-Based Design workflow built on MATLAB and Simulink, generating qualified HDL from executable models that have been simulated, verified, and traced against requirements. A core discipline of the practice is the transition from floating-point reference to fixed-point implementation: analyzing how word length, rounding, and overflow modes shape algorithm behavior, quantifying quantization noise across signal chains and control loops, and reshaping the algorithm itself: restructuring filters, rescaling states, choosing CORDIC or lookup over direct arithmetic — so that the model that passes simulation is the one that survives silicon. A core competency of the practice is DSP Builder for Altera FPGAs, whose Advanced Blockset X2CON uses to take high-level Simulink models down to optimized, vectorized VHDL for Altera FPGAs and SoCs, with push-button migration to hard floating-point DSP blocks where the application demands it. As a MathWorks Consulting Partner — one of roughly fifty worldwide — X2CON brings deep fluency in DSP Builder, HDL Coder, Fixed-Point Designer, and HDL Verifier. Embedded in what matters. X2CON Kft. is a Hungary-based embedded engineering consultancy serving aerospace, space, medical, automotive, nuclear, defense, and green energy customers across Europe, the UK, and the US. The team combines control, signal processing, RF, and embedded software expertise with a Model-Based Design backbone and operates end-to-end: from architecture assessment and compliance audit under DO-254, DO-178C, ISO 26262, and IEC 62304, through model, code, and HDL development, to training and post-delivery support. Every deliverable carries a commitment to industry standards, full knowledge transfer with no vendor lock-in, and the kind of close, responsive partnership that makes X2CON's engineers feel like part of the client's own team.
