This proposal deals with the automated layout of mixed analog and digital circuits. Optical interconnect interfaces which contain optoelectronic arrays integrated with digital processing capability require layouts in which noise sensitive analog circuits must be distributed throughout digital designs on a regular pitch for alignment with guided or free-space optical inputs. New layout tools must automatically incorporate application specific geometric constraints and analog noise requirements to produce layouts for these emerging technologies. The floor planning tool must have inputs from (1) a mask encapsulating the optical interface positioning requirements, called a keyhole mask,(2) standard cell and block compilers, and (3) the analog interfaces themselves. Problems being investigated are (1) creating a keyhole mask(2) modifying the Berkeley floor planning tool to provide feedback to the standard cell and block compilers based on keyhole mask inputs, and(3) modifying the Berkeley standard cell compiler to provide modified compilations based on inputs from the floor planning tool.

本建议涉及混合模拟和数字电路的自动布局。包含集成有数字处理能力的光电阵列的光学互连接口需要这样的布局，在该布局中，噪声敏感模拟电路必须以规则间距分布在整个数字设计中，以便与引导或自由空间光学输入对准。新的布局工具必须自动结合应用特定的几何约束和模拟噪声要求，以产生这些新兴技术的布局。 布局规划工具必须具有来自（1）封装光学接口定位要求的掩模（称为锁眼掩模）、（2）标准单元和块编译器以及（3）模拟接口本身的输入。正在研究的问题是（1）创建一个锁眼掩模（2）修改伯克利平面规划工具，以提供反馈的标准单元和块编译器的基础上的锁眼掩模输入，（3）修改伯克利标准单元编译器，以提供修改后的编译的基础上，从平面规划工具的输入。
