Abstract :
Based upon Rent´s rule, a new complete stochastic wiring distribution was rigorously derived that determines wire-length frequency for a homogeneous array of random logic gates and enables a priori estimation of the wiring requirements for future GSI systems. Unlike previous distributions that describe only local interconnect requirements, the new distribution provides a complete description of local, semi-global, and global wiring requirements, The new wire-length distribution and wire-net distribution was verified through comparisons to actual data from real systems, and a methodology to calculate the wire-length distribution for future GSI products was proposed, This new wiring length distribution is also used to determine optimal interconnect scaling in a three-tier multilevel network that minimizes chip size or maximizes clock frequency
