These configuration files define process layers, special rules, global variables, and ruleset-specific variables. The new interface allows for customization of these files to support particular cell design styles such as routing grid compliance and port placement files. MasterPort's constraint generation function has been enhanced to handle X and Y grid sizing separately, allowing independent port placement in the X and Y direction within an automated tool environment. Performance upgrades include improved handling of 45s and bent gates. The Vitesse H-GaAs IV process provides a platform that enables implementation of high performance communications systems at price levels far below other high performance technologies.
High density is created with a four-level aluminum metalization system.
The computer integrated manufacturing system will be installed at its two new fabrication sites in Newport, Gwent in Wales. The new system will be implemented in both fab sites by the end of 1997. The VSC8111 is suited for transmission and ATM applications, and is designed to meet the full Bellcore, ITU, and ANSI specifications for jitter performance. The device can be used with 19.44, 38.88, 51.84, or 77.76 MHz external reference clocks. In addition, both facility and equipment loopback modes are provided for system level diagnostics.
