摘要： A technique for reducing a circuit listing. According to examples of the technique, at least a portion of a circuit listing is analyzed to identify occurrences of a circuit structure made up of a plurality of circuit components. For each identified occurrence of the defined circuit structure, an injection data object is created corresponding to the plurality of components, and the injection data object is substituted into the portion of the circuit listing in place of the plurality of components. For each occurrence of the defined structure, one or more properties of the occurrence of the defined structure may be determined and contained by the corresponding injection data object.

摘要： Described herein are methods and systems for secure exchange of information related to electronic design automation. Information deemed sensitive and otherwise worthy of protection may be secured by methods such as encryption, obfuscation and other security measures. The secured information may be provided to an electronic design automation tool for processing without revealing at least some of the secured information. For instance, rule files related to integrated circuit manufacturability may be selectively annotated to indicate portions thereof deserving of protection. An encryption tool may be used to secure the information so indicated and generate a file comprising secured information related to electronic design automation. An electronic design automation tool may then unlock and use the secured information without revealing the same. For instance, the tool may be a physical verification tool capable of verifying whether any of the one or more integrated circuit layouts may violate one or more of the secured rules. An error report may be generated without revealing the secured rules.

摘要： Techniques for efficiently determining whether an interconnect line has an impedance component value below a maximum specified value. A specified maximum impedance component value is used to limit the number of interconnect lines that are analyzed by a parasitic extraction analysis process. An analysis window is created based upon the characteristics of the interconnect lines and the specified maximum impedance component value. The size of the window corresponds to the minimum length of the interconnect line that would have the specified maximum impedance component value. Once the analysis window has been created, the interconnect lines are examined to determine if any of them reaches to (or beyond) the analysis window, whereby interconnect lines that exceed the specified maximum impedance component value can be identified. If there are any remaining interconnect lines that have not been determined to exceed the specified maximum impedance component value through the use of the analysis window, then the impedance component values of these remaining interconnect lines can be specifically determined using a parasitic extraction process.

摘要： An electronic design automation process, such as a layout-verses-schematic analysis process, may recognize a representation of a device from physical layout design data. Information, such as geometric information separately obtained from the physical layout design data, is then associated with the recognized device representation. The associated information can subsequently be used in a later electronic design automation operation involving the recognized device representation.

摘要： One or more properties can be associated with a design object in a microdevice design. The design object may be an object in a physical layout design for a microdevice, such as a geometric element in a layout design. The design object also may be a collection of geometric elements in a layout design, such as a net, a cell in a hierarchical design, or even a collection of all of the geometric elements in a layer of a design. Still further, the design object may even be an item in a logical circuit design, such as a net in a logical circuit design for an integrated circuit. The values of one or more properties may be statically assigned for or dynamically generated during a design process performed by an electronic design automation tool. A property may be assigned a constant value or a value defined by an equation or other type of script that includes one or more variables. A property may be simple, where the definition of the property's value is not dependent upon the value of any other properties. Alternately, a property may be a compound property, where the definition of the property's value incorporates another, previously-determined property value. Still further, a property may be an alternative property, where the property is assigned one value definition under a first set of conditions and assigned another value definition under a second set of conditions. A first electronic design automation process may generate one or more property values. The generated property values then can be passed to another electronic design automation process in the design analysis flow for its use.
