Library Design

  • Dirk Jansen


The basic logic elements of an IC design, gates, and flip flops, are not made by the designer himself but mostly taken from libraries. The libraries provide a set of common and frequently used basic building blocks. In the area of digital design full custom design at the transistor level can be avoided. The risk of the design process, as well as the effort of verification, is thus reduced significantly. For analogue integrated circuits, when components are available, analogue libraries are used. Digital circuits are composed nearly entirely of library components, whilst analogue circuits are composed by 80% or more of library components. These library components are assembled and combined into the intended design. Only cells with special requirements or performances, which are unavailable as stock library components, are custom designed.
