This paper describes table symbols and their usefulness in High Pin Count Devices (HPCDs), particularly in enhancing readability and structure in printed schematics. Examples of simplified printed schematics and different methods for creating HPCD symbols are provided. Steps describe how to automatically map the PDB, and generic naming shows how to save valuable time when designing high pin count devices. Pre-defined and user-defined options and templates available from the 2002 ODA Library for Mentor Graphics Expedition are discussed, along with tips and examples for using each. Steps and examples provide a workaround for the common problems encountered when changing a pin name on a symbol. Alternatives to the power and ground connection symbols found in the 2002 ODA Library for Mentor Graphics Expedition show how to prevent interference with adjacent lines, and examples of using buses with the table symbols are also provided. As a reference, the naming convention for table symbols in the 2002 ODA Library for Mentor Graphics Expedition is shown.
