“…The benefit of including functional information in nominal timing analysis has already been reported in literature [2], [3]. In data path circuits the worst case circuit delay is strongly dependent on the selected values at the data inputs.…”

There is an increasing need for accurate timing information in nanoscale CMOS integrated circuit design. As delay variability increases design margins tend to be overly pessimistic in worst case circuit design. Conventional timing characterization methods do not take the function of the circuit into account. The use of program information tightens the result of circuit level timing analysis and reduces overestimation of worst case circuit delay. The method presented in this paper is able to analyze the impact of program specific details on the delay in the presence of process variations. Additionally we show how the gained information can be used to analyze different instruction sequences towards robustness in a microprocessor.

“…The process is repeated for all circuit modes, resulting in a set of clock models. Since AdvChar can detect false paths from control inputs, the clock models it produces are more accurate than those found by the method of [9]. …”

“…Thus the clock models it produces can be pessimistic because of false paths. An improvement to this method is proposed in [9], which is based on ModeChar. The method of [9] produces a set of clock models, each being valid for a particular mode of circuit operation.…”

“…An improvement to this method is proposed in [9], which is based on ModeChar. The method of [9] produces a set of clock models, each being valid for a particular mode of circuit operation. However, the accuracy of this method is also limited because it cannot detect any false paths involving control inputs.…”
