Design automation of a process portable Bandgap based Power-On-Reset circuit using the AnaGen Methodology

The increasing demand for robust and process-portable analog design solutions necessitates efficient automation techniques to address shrinking time-to-market timelines. This thesis presents a design automation flow for the rapid generation of a bandgap-based Power-On-Reset (PoR) circuit using the AnaGen methodology. The proposed approach integrates Python-based MOSAIC Environment with the Cadence Virtuoso design environment through the SKILL Interface to automate the sizing, simulation, and verification of the final circuit. By leveraging the AnaGen methodology, designers can produce a functional PoR circuit that meets desired specifications across multiple process nodes with minimal manual intervention. The automation framework not only significantly reduces human error but also achieves a notable reduction in design time compared to conventional methods. To validate this approach, a bandgap-based PoR circuit was sized and verified across a variety of process technologies. The results demonstrate that the automated design process produces circuits satisfying performance, stability, and area constraints consistently across technology nodes, requiring virtually no redesign. By eliminating repeated manual design iterations, the framework accelerates analog IP generation, making it a versatile tool for process-portable designs in industrial applications.
