Abstract

Due to the lack of proper design automation tools, designers are often forced to use full-custom design methodologies when designing analog and mixed-signal circuits. In this work, we discuss a design methodology based on parameterized cells intended for efficient design. The methodology is illustrated with the design of a 12-bit configurable current-steering DAC. Because the cells are parameterized, their layout must be described in a generalized way, resulting in a longer design time compared with a manual layout of a fixed circuit. However, the parameterized approach simplifies iteration of the layout process and block reuse.
基于参数化单元的数模转换器设计方法
由于缺乏适当的设计自动化工具,设计人员在设计模拟和混合信号电路时经常被迫使用完全定制的设计方法。在这项工作中,我们讨论了一种基于参数化单元的设计方法,旨在实现有效的设计。该方法以一个12位可配置电流转向DAC的设计为例进行了说明。由于单元是参数化的,因此必须以一般化的方式描述它们的布局,这与手动布局固定电路相比,需要更长的设计时间。然而,参数化方法简化了布局过程的迭代和块重用。
