As a result, the timing uncertainty of clock signal is increasing. In this paper, an efficient methodology for clock timing uncertainty- and skew-aware clock tree synthesis and analysis is proposed. We first present a statistical and less pessimistic methodology (as compared to the

The self-heating effect in silicon-on-insulator (SOI) technologies presents additional challenges in obtaining quality speculative SOI MOSFET models. A novel `shift-and-ratio¿ technique is developed to generate self-heating

It is verified to be accurate with Hspice simulations and suitable for SPICE model parameter extraction. It is also demonstrated that extraction of self-heating free I-V curves is not only desired for efficient SPICE model generation, but also required to accurately capture the true temperature dependences in the models.
