Abstract
Caesar is an interactive graphic editor that is used to generate layouts for VLSI circuits. It runs on a VAX-11/780 under the UNIX operating system with Berkeley extensions. Caesar has a unique and simple user interface. Phled is an enhanced version of Caesar that runs on a M68000-based engineering work station. Phled45 is based on Phled; its distinctive feature is the ability to enter layout containing 45° angles. The design considerations for implementing the capability to edit 45° shapes are discussed. The details of the implementation are presented.
