Abstract: A description is given of the Kinden environment, which combines object-oriented modeling and model-based reasoning to capture, integrate, and manage VLSI design process attributes and hierarchies. Related work is briefly reviewed, and the modeling of the design process is discussed, focusing on the Kinden approach. WebChip design has I/O pads; block design has pins. Chip design uses all metal layes available; block design may not use all metal layers. Chip is generally rectangular in shape; blocks can be rectangular, rectilinear. Chip design requires several packaging; block design ends in a … list of power elements
