Notes
Technical Notes: For the purposes of 3D006: 1. 'Electronic Computer-Aided Design' ('ECAD') is a category of “software” tools used for designing, analyzing, optimizing, and validating the performance of an integrated circuit or printed circuit board. 2. 'Register Transfer Level' ('RTL') is a design abstraction which models a synchronous digital circuit in terms of the flow of digital signals between hardware registers and the logical operations performed on those signals. 3. 'Geometrical Database Standard II' ('GDSII') is a database file format for data exchange of integrated circuit or integrated circuit layout artwork.
