A method involves determining failure in time rate for a circuit. The method may include obtaining circuit data regarding a circuit. The circuit may include a first wire segment and a second wire segment. The method may further include obtaining reliability data. The reliability data may describe a failure of the circuit over a pre-determined time period. The method may further include obtaining a thermal map. The method may further include determining a first failure rate for the first wire segment of the circuit. The first failure rate may be a probability that the first wire segment fails in a predetermined amount of time. The method may further include determining a second failure rate for the second wire segment of the circuit. The method may further include generating a model of the circuit. The model of the circuit may describe the first and the second failure rate of the circuit.

A method for visually merging design databases without generating a merged database of the design databases is disclosed. A first display window that is to display information from a particular database in non-overlay mode is assigned to the first stack position, and a second display window that is to display information from another database in overlay mode is assigned to a next stack position. The second display window is positioned relative to the first display window using position information received from the first display window via an inter-process communication channel.

Overlay display of data from different databases

Techniques are provided for improving performance of spatial queries by defining a grid that divides the domain space into cells, and then using a cell-to-item mapping to determine which items do not have to be individually evaluated against the location criteria of the spatial queries. Based on the cell to which an item belongs, the item may automatically qualify as a match, be automatically disqualified, or require item-specific evaluation. To account for items with size, the query window of a spatial query may be expanded. To limit the degree to which the query window is expanded, a plurality of grids may be established for the domain space, where each grid has differently sized cells, and items are assigned to grids based on the size of the items.
