Abstract: A licensed is obtained by an instance of a distributed application, and one or more other instances of the application are managed under the license. Collectively, the instances managed under the license behave as a single application. For instance, there is one point of user interaction, one point of input/output control, and one point of display for the collection of instances. Each of the controls can be the responsibility of one instance or distributed among various instances.

Abstract: A technique for distributed processing a partitioned model is provided based on tight functional coupling of multiple submodels of the model. The technique includes, in one embodiment, providing each submodel with a generic coupler to enable processing of the submodel on any simulator instance of any simulator. Submodels coupled with the generic couplers can be processed on the same or different computing units. The generic couplers facilitate communication between submodels through a common communication directory (CCD) by using functions of a generic coupler shared library. The generic couplers further use functions of the shared library to ensure integrity of data transmitted between submodels.

Abstract: A method and system select delay values from a VHDL standard delay file that correspond to an instance of a logic gate in a logic model. Then the system collects all the delay values of the selected instance and builds super generics for the rise-time and the fall-time of the selected instance. Then, the system repeats this process for every delay value in the standard delay file (310) that correspond to every instance of every logic gate in the logic model. The system then outputs a reduced size standard delay file (314) containing the super generics for every instance of every logic gate in the logic model.

Abstract: A method and system unbind a rise/fall tuple of a VHDL generic variable and create rise time and fall time generics of each generic variable that are independent of each other. Then, according to a predetermined correlation policy, the method and system collect delay values in a VHDL standard delay file, sort the delay values, remove duplicate delay values, group the delay values into correlation sets, and output an analysis file. The correlation policy may include collecting all generic variables in a VHDL standard delay file, selecting each generic variable, and performing reductions on the set of delay values associated with each selected generic variable.

Abstract: A method and system update a VHDL technology library (306) to incorporate correlated delay values by reading the VHDL technology library (306), inserting a tpd_super_rise_time generic declaration and a tpd_super_fall_time generic declaration for every VHDL gate model in the VHDL technology library (306), initializing other generic variables in every VHDL gate model in the VHDL technology library to an equation representing a correlation policy; and outputting an updated VHDL technology library. Then, the method and system bind correlated delay constants in a 3-dimensional variable data array structure to a VHDL technology library (306) using a VHDL package embedded with the correlation delay data.
