A continuation approach for computing parameter-dependent separatrices in SRAM cells

•A novel approach to analyze parameter-dependent separatrices in SRAM cells is proposed.•The method is constructed based on boundary-value problems solved via continuation techniques.•In this way, families of separatrices can be approximated in a computationally efficient manner.•The method is tested in a typical SRAM bit cell via the continuation platform COCO.•A comprehensive modelling of the cell is carried out using the EKV equations for CMOS transistors.
