  • 简介:改进IC的收益的一个新格子更少路由器被介绍。产量的改进被减少电路失败是可能的发生的临界区完成。更少的区域路由器从一个新奇成本函数有益于在路由过程期间计算临界区的这个格子,和启发式的联盟者在导致临界区是可能的更少的芯片区域上放模式。路由器也考虑另外的目的,例如路由布通率和网长度。获得更多的灵活性和更高的布通率利用格子更少路由。当超过99%维持路由布通率时,试验性的结果证明临界区被21%有效地平均减少。电子增补材料这篇文章(doi:10.1007/s11390-007-9092-9)的联机版本包含增补材料,它对授权用户可得到。

  • 简介:有在相反的方向驾驶的二种粒子的系统的结构的进化,即,由颜色域开车,被分子的动力学模拟调查。Gaussian自动调温器,在系统限制粒子的热速度的一个普通处理,被使用了以便说明热的驱散并且允许系统到达一个稳定的状态。随驱动力(F)的力量的增加,系统从一个开始随机的混合状态经历明显的结构的转变到分开的小巷并且在每条小巷描绘的一个状态,这被发现了仅仅一个种粒子存在。分析证明为小巷结构的形成的原因是F而且粒子磨擦的变化的增加不仅系数。当使用Gaussian自动调温器时,粒子磨擦系数成为F的功能。增加的F导致高粒子磨擦系数并且不可避免地为足够强壮的驱动力导致小巷形成。当在磨擦系数上提起F的效果并且选择一个经常的磨擦系数时,我们的结果显示出那因为在那里的给定的F总是存在比系统将比哪个发展成小巷结构高的磨擦系数的批评的值。
