The goal of this research is to develop a comprehensive methodology forthe synthesis of control dominated random logic circuits, targeting mixedpass-transistor (PTL) and static CMOS logic. Central to this methodologyis the integration of top-down design partitioning and logic synthesiswith bottom-up layout assembly. Specific tasks include: a) algorithmsfor initial Boolean network partitioning; b) novel BDD-based logicdecomposition driven by PTL/CMOS technology requirements; c) circuitsynthesis for mixed CMOS/PTL technology; and d) global level placement andfloorplanning to assume control over the wiring-induced delays in thefinal layout. An experimental synthesis system based on this methodology isnow being developed.

本研究的目标是开发一种综合的方法来合成控制主导的随机逻辑电路，目标是混合通管（PTL）和静态CMOS逻辑。该方法的核心是将自顶向下的设计划分和逻辑综合与自底向上的布局组装相结合。具体任务包括：a)初始布尔网络分区算法；b)由PTL/CMOS技术需求驱动的新颖的基于bdd的逻辑分解；c) CMOS/PTL混合技术的电路合成；d)全局布局和楼层规划，以控制最终布局中布线引起的延迟。目前正在开发一种基于这种方法的实验合成系统。
