Voltage-related analysis of layout design data

摘要

Disclosed are representative embodiments of methods, apparatus, and systems for voltage-related analysis of layout design data. According to embodiments of the disclosed technology, voltage association data objects are generated for drawn layers in a net of a layout design and voltage values or ranges of voltage values associated with the net are collected. The voltage values or ranges of voltage values are then associated with the voltage association data objects. A voltage-related analysis may be performed by searching the voltage association data objects according to a predetermined criterion.

主权项

1. One or more processor-readable storage device storing computer-executable instructions for causing one or more processors to perform a method, the method comprising:
generating, using the one or more processors, voltage association data objects for drawn layers in a net of a layout design, each of the voltage association data objects being generated for one of the drawn layers; collecting, using the one or more processors, a voltage value or range of voltage values for each geometric element of the net, wherein the net comprises two or more geometric elements; associating, using the one or more processors, the voltage values or ranges of voltage values collected for each of the geometric elements of the net with the voltage association data objects; and searching, using the one or more processors, the voltage association data objects according to a predetermined criterion to determine whether at least one of the geometric elements of the net matches the predetermined criterion without searching voltage values of the geometric elements of the net themselves.
