<italic>This paper presents a new timing driven approach for cell replication tailored to the practical needs of standard cell layout design. Cell replication methods have been studied extensively in the context of generic partitioning problems. However, until now it has remained unclear what practical benefit can be obtained from this concept in a… (More)
We present new concepts to integrate logic synthesis and physical design. Our methodology uses general Boolean transformations as known from technology-independent synthesis, and a re-cursive bi-partitioning placement algorithm. In each partitioning step, the precision of the layout data increases. This allows effective guidance of the logic synthesis… (More)
In this paper it is shown how a circuit, given as a net-list of gates, can be transformed into a code-disjoint circuit. Carefully selected gates of the separately implemented parity bit are utilized for the optimization of the necessary area overhead.
In this paper it is shown how a circuit, given as a net-list of gates, can be transformed into two diierent types of code-disjoint circuits. A new method for a joint design of the functional circuit, the output parity and the input parity is proposed. Carefully selected internal nodes of the functional circuit are utilized to reduce the necessary area… (More)
