PLDSection 09: Hardware Certification (DO-254)
Definition
A general category of integrated circuits whose logic function is defined by the user after manufacture through programming rather than during the semiconductor fabrication process. PLDs include SPLDs (simple PLDs such as PALs and GALs), CPLDs, and FPGAs.
Where This Shows Up
PLDs are a central concern in DO-254 because their programmable nature means that design errors can be introduced during the logic design phase, similar to software development. Unlike fixed-function hardware, PLDs require a structured design assurance process covering requirements, design, implementation (synthesis and place-and-route), and verification. The specific type of PLD affects the applicable verification strategies.
