Bottom-Up High -Level Current Macro-Models for Logic Blocks

85 p.Thesis (Ph.D.)--University of Illinois at Urbana-Champaign, 2003.High-level power-grid design and analysis requires a current macro-model for different logic blocks that are both easy to use and automatically constructed. The main contribution of this research is the development of current macro-models for combinational logic blocks in the frequency domain. The current waveforms obtained from the macro-models can be used to estimate energy for every input vector pair (energy per cycle) and peak-current for every input vector pair (peak current per cycle), apart from being useful in analyzing power grids at higher levels of abstraction. Another contribution of this research is the automatic construction of these macro-models based on a simple characterization flow.U of I OnlyRestricted to the U of I community idenfinitely during batch ingest of legacy ETD
