Abstract
A system and method for efficiently creating layout for a standard cell are described. A standard cell to be used for an integrated circuit uses a full trench silicide strap as drain regions for a pmos transistor and an nmos transistor. Multiple unidirectional routes in metal zero are placed across the standard cell where each route connects to a trench silicide contact. Power and ground connections utilize pins rather than end-to-end rails in the standard cell. Additionally, intermediate nodes are routed in the standard cell with unidirectional routes.
