Abstract
A method, system and program product implementing storage of a (power or ground) mesh plane file using a multiple line shape, possibly with the storage of lines also, to reduce file size. In addition, the invention implements an activate-substantial-portion-and-remove technique to generate mesh planes rather than the conventional additive approach, which improves the speed of designing the IC carriers. A resulting mesh plane design file may be as much as half the size of a file generated using the conventional line-by-line and storage approaches.
Claims28
A method of generating a mesh plane for an IC carrier design, the mesh plane being defined on a field of grid points, the method comprising steps of:
- activating a substantial portion of grid points of an intended mesh plane with active lines;
- removing at least one active line to generate the mesh plane;
- and
- storing a set of active lines of the mesh plane as a multiple line shape.
A method of generating a mesh plane for an IC carrier design, the method comprising steps of:
- generating a mesh plane having a plurality of active lines;
- and
- storing a set of active lines of the mesh plane as a multiple line shape.
A computer program product comprising a computer useable medium having computer readable program code embodied therein for generating a mesh plane for an IC carrier design where the mesh plane is defined on a field of grid points, the program product comprising:
- program code configured to activate a substantial portion of grid points of an intended mesh plane with active lines;
- program code configured to remove at least one active line to generate the mesh plane;
- and
- program code configured to store a set of active lines of the mesh plane as a multiple line shape.
A computer program product comprising a computer useable medium having computer readable program code embodied therein for generating a mesh plane for an IC carrier design, the program product comprising:
- program code configured to generate a mesh plane having a plurality of active lines;
- and
- program code configured to store a set of active lines of the mesh plane as a multiple line shape.
An IC carrier design system comprising:
- a mesh plane generating unit including:
- means for activating a substantial portion of grid points of an intended mesh plane with active lines, the grid points being part of a field used to define the mesh plane;
- and means for removing at least one active line to generate the mesh plane;
- and
- a mesh plane storage unit including means for storing a set of active lines of the mesh plane as a multiple line shape.
