摘要： A process and apparatus are provided for tiling objects, such as design memories, in one or more respective object locations in a layout pattern. For each object, the following steps are performed recursively based on a comparison of at least one of a capacity and a width of the object and that of the respective object location: (1) do nothing; (2) reconfigure the object to have a different capacity and/or width; and (3) split the object into two or more separate objects. The recursion is repeated for each reconfigured object and each separated object.

摘要： A method of generating a timing model for a customer memory configuration, by generating a plurality of template memory netlists for a given RRAM design. Timing models for the template memory netlists are produced and stored in a first database. The template memory netlists are stored in a second database. A netlist for the customer memory configuration is generated and compared to the template memory netlists to find a match. When a match is found, one of the timing models that is associated with the matching template memory netlist is used as the timing model for the customer memory configuration. When a match is not found, two of the template memory netlists that bound the customer netlist are found, according to at least one parameter, and the timing model for the customer memory configuration is interpolated based on the two bounding template memory netlists.

摘要： A method and apparatus are provided for receiving a list of design memories, wherein each type of design memory in the list has a name and at least one instance. A pre-placement model is associated with each named memory type in the list. The design memories in the list are mapped to an integrated circuit layout pattern, wherein at least one memory type comprises first and second instances that are mapped differently from one another. After mapping, at least one of the first and second instances is renamed to have a different name than the other. A post-placement model is then associated with each named memory type in the list, including a separate model for each renamed design memory.
