“…Therefore, a correct static timing analysis for flexible TFT circuits is indispensable. STAF [Hsu et al 2010] is a state-of-the-art static timing analyzer for TFT circuits with mechanical strain consideration. To deal with the mobility variation under mechanical strain, STAF includes a block-based static timing analysis (STA) algorithm to identify the circuit timing with mechanical strain consideration.…”

“…To more accurately estimate the solution quality of the generated cell placement, the static timing analysis tool is performed after each iteration of the SA procedure. In FlexiPlace, the timing degradation is estimated by performing the STAF [Hsu et al 2010]. Both factors are calculated as percentages and the routing overhead is estimated based on half-perimeter wire length (HPWL).…”

Mobility is the primary device parameter affecting circuit performance in flexible thin-film transistor (TFT) technologies, and is particularly sensitive to the change of mechanical strain and temperature. However, existing algorithms only consider the impact of mechanical strain in cell placement of flexible TFT circuits. Without taking temperature into consideration, mobility may be dramatically decreased which leads to circuit performance degradation. This article presents the first work to minimize the mobility variation caused by the change of both mechanical strain and temperature. Experimental results show that the proposed algorithms can effectively and efficiently reduce the increasing critical path delay. ACM Reference Format: Lin, J.-L., Wu, P.-H., and Ho, T.-Y. 2014.

This paper presents a SPICE-based simulator, FlexiAnalyzer, for flexible thin-film transistor (TFT) circuits. This simulator performs four types of analysis: yield analysis, aging analysis, performance analysis, and weak spot analysis. This simulator considers three important effects: 1) threshold voltage variation of manufacturing process; 2) threshold voltage shift due to aging effect; and 3) mobility change due to bending effect. Six different OLED pixel drivers designed in 8-m amorphous silicon TFT technology were used in simulation results. The proposed tool provides a good solution for designers to evaluate the performance and yield of flexible TFT circuits.Index Terms-Flexible TFT circuits, spice, circuit analyzer, bending effect, aging effect.
