Abstract
A system, method and media for locating and defining process sensitive sites isolated to specific geometries or shape configurations within chip design data. Once a systemic process sensitive site is identified, a 3D design checking deck is coded and executed through a design checker on physical design data. Target match shapes are produced and embedded back into the design data. Pictures, maps and coordinates of process sensitive sites are produced and sent to a website library for reference.
Claims20
A method for locating process sensitive areas of a design, comprising the steps of:
- scanning a pre-release or released device for shape configuration data for process sensitive sites that cause productivity loss;
- coding the shape configuration data such that it is recognizable to a design checker;
- and
- using the design checker to identify target matches where such shape configuration data is present in the design.
A physical design characterization system which comprises:
- a release environment which comprise physical design data files;
- a queuing system that controls what physical design data files are released to a 3D design checker;
- a design check library which contains physical design structures of process sensitive regions from previously released devices;
- a 3D design checker connected to the design check library and a runtime environment;
- and
- a runtime environment which operates on the physical design data files using the 3D design check and produces target matches.
A program storage device readable by machine, tangibly embodying a program of instructions executable by the machine to perform the method steps for locating process sensitive areas of a design, the method steps comprising:
- loading into memory for released devices shape configuration data for process sensitive sites that cause productivity loss such data being coded such to be recognizable to a design checker;
- loading into memory physical design data for the design;
- and
- using the design checker to produce target matches at the locations where such shape configuration data is present in the design.
