quest-defense.com LinkedIn

Quest Defense designs avionics, control systems, and digital components for aerospace and defense contractors. The tech stack—LDRA, VectorCAST, QuestaSim, Vivado, SystemVerilog, DO-254 compliance tooling—reflects a company focused on safety-critical verification and FPGA modernization rather than general software. Active projects span nuclear power plant control verification, next-generation avionics, and FPGA component replacement, while pain points cluster around certification (DO-254, safety-critical compliance) and test coverage—the core friction points in regulated aerospace engineering.
