1. A method, comprising: projecting Network on Chip (NoC) elements of a NoC to a grid layout based on specified topological information; and automatically generating the NoC from the projection of the NoC elements to the grid layout; wherein the projecting NoC elements of the NoC to the grid layout based on the specified topological information comprises: projecting a plurality of nodes, a plurality of routers and a plurality of links onto the grid layout based on the specified topological information, wherein the projected plurality of routers, the plurality of nodes, and the plurality of links are disabled; selectively enabling ones of the plurality of routers, ones of the plurality of nodes, and ones of the plurality of links on the grid layout based on one or more constraints for one or more layers of the NoC; providing NoC agents on enabled ones of the plurality of nodes of the grid layout; providing traffic between the provided NoC agents; and mapping the traffic to the enabled ones of the plurality of routers and the plurality of links of the NoC.
