A cell generator for UTMC's gate array library of core logic cells is implemented using Cadence&reg; Relative Object Design (ROD) software. The ROD functions use design rules to create and align ROD objects. Design rules can be specified for different foundries and technologies, or can be altered to special design requirements. ROD user-defined handles are created to facilitate internal routing and to accommodate different UTMC architectures. Hierarchy is used to minimize the ROD code, and a Cadence&reg; SKILL Makefile generates the entire library automatically.

Gate array cell generator using cadence relative object design

Functional and geometrical sub-components of logic circuits are defined and used in the design of integrated circuits to facilitate the transformation of an integrated circuit design for fabrication at foundries with different design rules.

Method for fabricating integrated circuits

A method of manufacturing an integrated circuit including adjusting a parameter of the operation of the integrated circuit, such as power dissipation, after prototype testing by changing only one mask. If prototype testing indicates that the performance specification for power dissipation, for example, is not met, the power dissipation can be adjusted by changing the size of the active areas to change the channel width of the gates of the circuit, by changing the size of the patterns of the active area masks. To decrease power dissipation, the size of the active area is decreased. Only the active mask need be changed. Preferably, the active area around the original contacts are maintained so that the positions of the contacts need not be changed. Consequently, the mask for defining the position of the contacts and the masks for defining the metallization layers need not be changed. To increase power dissipation, the size of the active areas is increased. The values of other parameters may be changed, as well.
