Abstract: A device for displaying a disabled parking permit includes a housing with a hook for hanging the device from a rear view mirror in a motor vehicle. The disabled parking permit is provided on opposite faces of a flexible sheet placard that is wound onto a spring-loaded roll contained within the housing. The placard can be pulled down from a slot opening on the bottom of the housing to a fully extended position for displaying the disabled parking permit in a manner that allows visibility from both the front and rear of the vehicle when the vehicle is parked. The placard retracts and rolls up within the housing, onto the spring-loaded roll, to avoid obstruction of view when driving.

Abstract: A system and method for analyzing a circuit. In one embodiment, a tool generates path information based upon a netlist that describes the circuit. A synthesizer generates a nodal data structure responsive to the path information. A parser is operable to parse a nodal query to provide a tree structure such that each leaf of the tree structure comprises a segmented expression of the nodal query. A resolver accesses the nodal data structure and tree structure in order to generate a solution set that satisfies at least one of the segmented expressions.

Abstract: A system and method for waiving a verification check associated with a circuit design. In one embodiment, a first engine integrates waiver options associated with the circuit design's design objects into a hierarchical verification tree having the verification check. Responsive to a verification check violation, a second engine traverses a portion of the hierarchical verification tree to determine a list of applicable waivers. A third engine resolves the list of applicable waivers to determine the disposition of the verification check violation.

Abstract: Systems and methods for filtering circuit analysis results are disclosed, and involve receiving circuit analysis results, identifying a duplicate circuit analysis result among the received circuit analysis results, and outputting a list of circuit analysis results that excludes the duplicate circuit analysis result.
