自动生成模拟和混合信号(AMS)电路的最新进展是使用标准的数字工具流将数字标准单元和一组辅助单元(auxcell)组合在一起组成AMS电路。到目前为止,为每个新PDK生成辅助单元布局是自动生成AMS组件流程中的最后一个手动步骤,这限制了可用的辅助单元,降低了自动生成AMS设计的最佳性。为了解决这个问题,我们提出了AuxcellGen,一个自动生成辅助单元布局和性能模型的框架。Aux-cellGen使用神经网络(NN)生成寄生感知辅助细胞性能模型,针对给定的设计目标自动调整和优化辅助细胞原理图,并自动生成辅助细胞布局。该框架通过自动生成锁相环的三状态缓冲辅助单元和SRAM的传感器放大器辅助单元来证明,这些辅助单元跨越一系列用户规格,与标准单元和存储位单元间距兼容。
Recent advances in auto-generating analog and mixed-signal (AMS) circuits use standard digital tool flows to compose AMS circuits from a combination of digital standard cells and a set of auxiliary cells (auxcells). Until now, generating auxcell layouts for each new PDK was the last manual step in the flow for auto-generating AMS components, which limited the available auxcells and reduced the optimality of the auto-generated AMS designs. To solve this, we propose AuxcellGen, a framework to auto-generate auxcell layouts and performance models. Aux-cellGen generates a parasitic-aware auxcell performance model using a neural network (NN), auto-sizes and optimizes auxcell schematics for a given design target, and auto-generates auxcell layouts. The framework is demonstrated by auto-generating tristate buffer auxcells for PLLs and sense-amplifier auxcells for SRAM across a range of user specifications that are compatible with standard cell and memory bitcell pitch.
