A system, and corresponding method, is described for finding the optimal or the best set of routes from a master to each of its connected slaves, for all the masters and slaves using an interconnect, such as a network-on-chip (NoC). Some embodiments of the invention apply to a class of interconnects that utilize a two-dimensional mesh topology, wherein a set of switches are arranged on a two-dimensional grid. Masters (initiators or sources) inject data packets or traffic into the interconnect. Slaves (targets or destinations) service the data packets or traffic traveling through the interconnect. The interconnect includes switches and links that are part of a path. Additionally, one or more optimal routes, which is defined by the system, move the traffic in a way that avoids deadlock scenarios.

System and method to determine optimal path(s) and use load balancing in an interconnect

A tool is disclosed that includes a discriminant module. The discriminant module finds one configuration, which is selected from many different possible and legal configurations, that is optimal. The optimal configuration is translated into a set of optimized parameters (identified from the library of parameters that the user can select from) and provided to the designer. The designer reviews (and can manually revise or change) the optimized parameters. The optimized parameters are translated into engineering parameters. The engineering parameters are passed, as an input, to the RTL generation module. The RTL generation module produces the RTL description of the hardware function that is optimal and meets the designer's defined requirements.

Optimization of parameters for synthesis of a topology using a discriminant function module

A system, and corresponding method, is described for finding the optimal or the best set of routes from a master to each of its connected slaves, for all the masters and slaves using a Network-on-Chip (NoC). More precisely, some embodiments of the invention apply to a class of NoCs that utilize a two-dimensional mesh topology, wherein a set of switches are arranged on a two-dimensional grid. Masters (initiators or sources) inject data packets or traffic into the NoC. Slaves (targets or destinations) service the data packets or traffic traveling through the NoC. The NoC includes switches and links. Additionally, the optimal routes defined by the system includes moving the traffic in a way that avoids deadlock scenarios.

In accordance with various embodiments and aspects of the invention, systems and methods are disclosed that can automatically find the best legal configuration that will be optimal with respect to a given set of requirements or metrics, such as: area, timing, and power. A designer defines the metrics or requirements, which represent the functional needs. A designer typically selects a set of parameters from a group of parameters available to user, which are user selectable parameters. The best parameters, from which the user can select parameters, are identified, and provided to the user. A constraint solver module ensures all rules are enforced and finds all legal parameters that fulfil the user intent. The constraint solver module generates configurations that meet the requirements and are legal configurations.
