A STANDARD BLOCK architecture for integrated circuit (IC) design. The STANDARD BLOCK architecture provides a new level of abstraction with a granularity and regularity that is most appropriate for the physical implementation of complex, large scale deep-submicron IC designs. To this end, the STANDARD BLOCK architecture combines the advantages of standard-cell-based and functional-block-based architectures. The STANDARD BLOCK architecture includes a STANDARD BLOCK form that is physically constrained having one fixed or quantized dimension and one variable dimension that ranges between predefined limits. The STANDARD BLOCK granularity is larger than the standard cell granularity such that each STANDARD BLOCK includes a plurality of standard cells. In the STANDARD BLOCK architecture, each STANDARD BLOCK has flexible physical design properties. In this design style, the STANDARD BLOCKs are provided as general physical abstractions such that each STANDARD BLOCK is akin to a black box model with the majority of its internal design aspects invisible to the top-level assembly tool while selected design aspects remain visible. The global design aspects of each STANDARD BLOCK include its fundamental architectural and structural characteristics, including its physically constrained form, and its fundamental power, timing, clock and signal integrity properties. With the STANDARD BLOCK architecture, quantization of the STANDARD BLOCKs' form dimensions relative to IC dimensions can be substantially constant and scalable with increased IC complexity. Thus, STANDARD BLOCK architecture can be applied to any IC designs as well as any intellectual property (IP) designs.

Standard block architecture for integrated circuit design

An integrated circuit (IC) architecture with STANDARD BLOCKs. The IC architecture forms a layout that includes a plurality of STANDARD BLOCKs, top-level cells, and hard IP blocks. The STANDARD BLOCKS form row-based or column-based STANDARD BLOCK ARRAY configurations in which STANDARD BLOCKs are placed adjacent to each other in a row or column configuration with their fixed or quantized dimension aligned and oriented perpendicular to the STANDARD BLOCK ARRAY direction. Individual STANDARD BLOCK ARRAYs can be spaced apart forming channels between them to allow for routing interconnections, or overlapping one another in a flipped configuration sharing VDD or GND power rails. The IC layout includes sites reserved for top-level cells that are placed in channels between STANDARD BLOCK ARRAYs, around the perimeter of STANDARD BLOCKs, or arranged in a staggered or diagonal configuration inside the STANDARD BLOCKs. The layout of the IC further includes power grid and clock grid structures providing, respectively, power and ground and clock distribution. Each of the STANDARD BLOCKs has a form that is physically constrained such that its dimensions feature one fixed or quantized dimension, and one variable dimension that ranges between predefined limits; a granularity larger than a standard cell granularity such that each STANDARD BLOCK includes a plurality of standard cells; and flexible physical design properties.
