Abstract

Matching placement and routing is very important in layout design of high performance analog circuits. This paper presents a matching-based placement and routing system for custom layout design automation especially for analog or mixed-signal designs. The system explores various device-level matching-placement and matching-routing patterns to generate the most compact and high-quality layouts. Inputting a circuit netlist, the system automatically analyzes the circuit and extracts matching devices to form several matching device groups. Then, it selects the best matching placement and routing pattern for each device or device group to optimize and to meet the overall placement objectives and constraints. All patterns are user-configurable, stored in the pattern database, and portable from design to design. After the layout of each device and device group is generated and placed, the constraint-driven shape-based router is invoked to complete the layout. The overall system can easily generate high-quality layouts and greatly reduce the layout design time.

一种基于匹配的模拟设计布线系统

在高性能模拟电路的布局设计中，布线匹配是非常重要的。本文提出了一种基于匹配的布线系统，用于自定义布线设计自动化，特别是模拟或混合信号设计。该系统探索各种设备级匹配放置和匹配路由模式，以生成最紧凑和高质量的布局。系统输入电路网表，自动对电路进行分析，提取匹配设备，形成多个匹配设备组。然后，为每个器件或器件组选择最佳匹配的布局和布线模式进行优化，以满足总体布局目标和约束。所有模式都是用户可配置的，存储在模式数据库中，并且可以从设计移植到设计。在生成并放置每个设备和设备组的布局后，将调用约束驱动的基于形状的路由器来完成布局。整个系统可以轻松生成高质量的布局，大大缩短布局设计时间。
