This paper presents an overview on automated analog design migration. Different approaches dedicated to design migration of both circuit and layout phases are discussed. It is shown that in order that a solution be accepted by the design community, it must reflect all design information, heuristics and choices made in the original design to the target design. A tool based on design extraction is presented in more details with a test case.

“…Most of the layout migration algorithms are based on layout compaction [4], [5], [7], [8], [9], since it closely resembles the source layout [15]. It automatically constructs a symbolic structural template to preserve layout topology, design rules, symmetry and matching information from an existing layout.…”

This paper presents an analog layout migration methodology to quickly provide multiple layouts while keeping similar or better circuit performance. Unlike previous works that often generate a single layout that has exactly the same topology with the original layout, this new migration algorithm is able to provide results with different aspect ratios. First, various placement constraints, including topology, matching, and symmetry, are extracted from the original layout. The extracted constraints are hierarchically stored into a topology slicing tree. Placement is performed from the bottom tree nodes to the root tree node. In each tree node, multiple placements for the subtree are recorded. All possible placements under the constraints are recorded in the root node. This algorithm has been successfully applied to a variable gain amplifier and a folded cascode operational amplifier migrating from UMC 90nm to UMC 65nm. The experimental results validate that our approach can provide reasonable layouts, even a better result almost in no time.

“…For layout migration there is more commercial tool support available. The authors are aware of ALX from Magma [6], Osiris from IN2FAB [7] and Mentor's Chameleon Art [8]. The latter two tools are proprietary and available as design migration services only.…”

Layout generation remains a critical bottleneck in analog circuit design. It is especially distracting when re-using an existing design for a similar specification or when transferring a working design to a new technology. This paper presents a new methodology for layout generation of analog circuits that is based on a modular circuit design and a so-called "executable design flow description". This is created once manually and allows to describe the layout in a technology independent and parameterizable manner assuring a consistent view of circuit and layout design. Complex layouts can be created in negligible time, achieving an early involvement of layout effects in the circuit design. Furthermore, the parameterization of the design description allows simplified technology transfer and seamless access to sizing tools.
