The document discusses tools needed for chiplet-based integrated circuit design. It notes that while EDA companies offer many necessary design tools, they are currently offered piecemeal. Standards for defining chiplets electrically, mechanically, and thermally would help enable a chiplet marketplace. zGlue has developed a data exchange format for defining chiplets and their mechanical I/O, and power specifications to allow chiplet vendors to list their products while maintaining access control. The document promotes zGlue's ChipBuilder software and shuttle prototype program for designing with chiplets.
