A Custom-Cell Identification Method for High-Performance Mixed Standard/Custom-Cell Designs

: Over the years, many design methodologies/tools and layout architectures have been developed for datapath-oriented designs. One commonly used approach for high-speed datapath designs is the full-custom design method targeted to bit-sliced or bit-alignment layout architectures. Using this approach, designers can fully exploit design properties, such as various circuit designs, structural regularities and layout structures, to develop high-speed, low-power and highdensity datapath designs. However, the main drawbacks of this approach are threefold: (1) extremely high development cost, (2) very long development time, and (3) difficult to migrate the custom design to a new technology. The other approach is the HDL-based synthesis method targeted to the standard-cell layout architecture. This approach is highly productive and easy to implement. However, due to lack of the ability to exploit the regularity properties of datapath designs, it’s mostly suitable to produce low/medium-speed d...
