移动性是影响柔性薄膜晶体管（TFT）技术中电路性能的主要设备参数，并且对机械应变和温度的变化特别敏感。但是，现有算法仅考虑机械应变对柔性TFT电路的细胞放置的影响。不考虑温度，可能会大大降低迁移率，从而导致电路性能降解。本文介绍了最小化机械应变和温度变化引起的迁移率变化的第一项工作。实验结果表明，所提出的算法可以有效，有效地减少临界路径延迟的增加。
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.
