Logic-circuit layout for large-scale integrated circuits

Logic-circuit layout for large-scale integrated circuits

A VLSI chip (100) has multiple annular rings (122) of circuit cells, interspersed with annular wiring channels (123) for interconnecting the cells. Another wiring layer runs perpendicular to the rings. A central chip area (110) contains all the I/O connections for the chip.
