Characterization of the Performance Variation for Regular Standard Cells with Process Non-idealities
In IC manufacturing, the performance of standard cells often varies due to process non-idealities. Some research work on 2-D cell characterization shows that the timing variations can be characterized by the timing model. However, as regular design rules become necessary in sub-45 nm node circuit …

Probabilistic analysis of meanline compressor rotor performance
This thesis addresses variability in aerodynamic performance of a compressor rotor due to geometric variation. The performance of the rotor is computed using a meanline model that includes the effect of tip clearance blockage, calculated by assuming the tip leakage behaves like a wake in a pressure …
