"Opti-MOS: A Layout Tool For Integrating Optical Superstructures on CMO Devices"

本文讨论了模拟和数字混合电路的自动布局。包含集成了数字处理能力的光电阵列的光互连接口要求布局，其中噪声敏感模拟电路必须分布在整个数字设计中，以规则的螺距与引导或自由空间光学输入对齐。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，以生成这些新兴技术的布局。平面图工具必须有以下输入：(1)封装光接口定位要求的掩模，称为锁孔掩模，(2)标准单元和块编译器，以及(3)模拟接口本身。正在研究的问题是(1)创建一个钥匙孔掩码(2)修改伯克利楼层规划工具，以根据钥匙孔掩码输入向标准单元和块编译器提供反馈，以及(3)修改伯克利标准单元编译器，以根据楼层规划工具的输入提供修改后的编译。

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.
