The goals of HY437 include gaining understanding, insight and familiarization with state-of-the-art EDA (Electronic Design Automation) Algorithms, and automated flows for the design and testing of digital electronic circuits.
The course focuses on (1) Logic Synthesis Algorithms, (2) Technology Mapping algorithms onto standard-cell technology libraries and (3) ATPG (Automatic Test Pattern Generation) algorithms for testing manufacturing faults, i.e. all implementation stages PRIOR to physical design. The course presents a set of both exact and heuristic algorithms similar to those implemented in commercial tools, such as Synopsys DC (Design Compiler) or Cadence RC Compiler.
Upon successful completion of the course, students will be accustomed with the following concepts and skill sets:
- Understanding and Insight on the theory of Exact and Heuristic CAD Algorithms
- Understanding and Insight on the various types of algorithms and their application/applicability to the solution of a particular problem
- Knowledge of specific practical industrial CAD algorithms for Combinational Circuit Optimisation, Area/Delay Trade-offs, Technology Mapping and Manufacture Testing
- Algorithm Complexity understanding and Evaluation of alternative solution methods
- Insight on the design process of new algorithms
