An efficient electronic structure for circuit design, testing and/or manufacture for validating a cell layout design using an intelligent engine trained using selectively arranged cells selected from a cell library. An initial design rule violation (DRV) prediction engine is initially trained using a plurality of pin patterns generated by predefined cell placement combinations, where pin patterns are pixelized and quantified and is classified as either (i) a DRV pin pattern (i.e., pin patterns likely to produce a DRV) or (ii) a DRV-clean pin pattern (i.e., pin patterns unlikely to produce a DRV).

Pin accessibility prediction engine

A method for routing a circuit device having an array of bump pads includes identifying a routing direction associated with a bump, generating a power strap and a ground strap based on the routing direction, forming a routing channel in accordance with the routing direction, setting a start point and an endpoint in the routing channel, and connecting the start point and the endpoint using a wire within the routing channel. The method further includes placing the start point to a power or ground strap in response to a target power/ground ratio.

IR-aware sneak routing

A method for designing an integrated circuit (IC) includes, in part, dividing the wires disposed in the IC into a multitude of segments each having a length extending from a first end point to a second end point. Each segment is then widened without overlapping any adjacent object. As an example, an intermediate, or expanded, segment is formed that includes the first and the second end points and has a size to overlap with an adjacent object. The method includes identifying regions in the adjacent objects that overlap with the expanded segment. For each of the identified regions, an expanded region is formed, which has a shape and size to enclose the identified object with additional spacing around the perimeter. Next, the size of the expanded segment is reduced to form the wide segment such that the wide segment does not overlap any of the adjacent expanded objects.
