Estimation of delay correlations is one of the most challenging problems in SSTA. This is because cell delay depends on a number of factors in a complex manner, which makes complex the estimation of correlations as well. In this paper, we introduce a technique to compute cell-to-cell and path-to-path delay correlations, which allows considering the effects of cell-level input/output edge, input slope...
Asynchronous logic is a hot topic due to its interesting features of power saving, low noise and robustness to parameters variations. Beside of the benefits of asynchronous design technique, the lack of automatic design and analysis tools made it hard to apply them in the new designs. Timing analysis is a necessary step in automatic design process and optimization of asynchronous circuits. On the...
This paper presents how airfield system capacity and delay analysis proceeds based on computational simulation. It analyzes the factors that influence airfield system. SIMMOD (FAA airport and airspace simulation model) is used to carry on the simulation which involves the influential factors to ensure high level of details and close reality in terms of air traffic control constraints and airfield...
With the adoption of statistical static timing analysis (SSTA), the characterization of standard cell libraries for delay variations and output transition time (output slew) variations, referred to as statistical characterization, is becoming essential. Statistical characterization of intra-cell mismatch variations as well as inter-chip variations need to be performed efficiently with acceptable accuracy...
