Across-chip length variation (ACLV), the controlled-circuit design and off-chip-driver performance are also discussed.","PeriodicalId":300310,"journal":{"name":"Proceedings.

In this paper a methodology is described that adds formal verification (FV) to the verification process without requiring any knowledge of FV languages. It solely uses the finite state machine notation, which is familiar and intuitive to designers. Another problem of FV is state space explosion. If this occurs we can switch to random simulation within an hour without losing any effort. The results show that FV is at least as fast as random simulation and it is superior in terms of verification quality because it is exhaustive.","PeriodicalId":300310,"journal":{"name":"Proceedings.

These projections are consistent with 1994 NTRS technology and cycle time forecasts and use physical and stochastic models that tightly couple together the device, circuit and system levels of the CMOS ASIC design hierarchy. Verified by HSPICE and actual microprocessor implementations, these models project optimal supply voltages for 0.25-0.07 /spl mu/m generations to scale from 900 mV to 500 mV and power densities to increase from 3 W/cm/sup 2/ to 10 W/cm/sup 2/ in wire limited high performance CMOS ASIC systems.","PeriodicalId":300310,"journal":{"name":"Proceedings.
