Title:
自動回路設計のための方法および装置
Document Type and Number:
Japanese Patent JP2006527429
Kind Code:
A
Abstract:
Methods and apparatuses to automatically modify a circuit design (e.g., a synthesis solution) according to the sensitivity in design parameters with respect to the possible deviation in the subsequent implementation (e.g., placement and routing) of the circuit. In one aspect of the present invention, a method to design a circuit includes: determining likelihood of a design constraint being violated in an implementation of a first circuit design (e.g., a technology specific netlist with or without a placement solution); and, modifying the first circuit design to reduce the likelihood of the design constraint being violated. In one example, the implementation of the first circuit design includes a routing solution for implementing the first circuit design; and, the first circuit is modified through sizing an instance of a logic element, buffering a signal, load shielding for a signal, or other operations.
