Analog design remains a manual task because of the complexity of the interactions among devices. Automation tools dedicated to analog circuits are not as mature as the digital automation ones, but have been improved a lot at a point that they can help at individual steps in the analog design flow. Our approach is to propose a semi-automated analog placement controlled by the designer, following an organization in row similar to a digital circuit structure. The results show the ability of our tool at generating multiple layouts respecting designer's constraints.
