“…However, no significant details about the legacy layouts' interconnects are kept in the conversion process, as only simple recursive algorithms are used to detect the nets of the original design. LDS Analyser (2012) [61], an add-on to the previously presented LDS, aims to convert a legacy layout via an interactive graphical interface into LDS templates. Interconnects are captured by selecting path segments and assigning them a net name and are represented in data structures that assign points for the vias and line segments for the paths.…”

“…Focusing on the creation of analog layouts, one can divide approaches into bottom-up generator-based [1,2,3,4], template-based [5,6], and top-down optimization-based [7,8,9,10] all of which may interact with each other. The high structural flexibility but long run time of optimization-based approaches is well known, as is the reduced structural flexibility but short run time of generator-based methodologies [11].…”

Analog layout design is a costly and error-prone task since analog synthesis is still far from applicable. It is expected that procedural bottom-up generators managing constructive tasks will be part of future synthesis flows. Generators contain expert knowledge implicitly within complex and hard-to-understand source code. Due to a lack of explicit layout definition and uncaptured design intent, generator layouts can hardly be adapted by constructive algorithms directly. Thus, synthesis flows need to adapt layout blocks by varying generator parameters which results in computation-expensive optimization. This paper introduces MESH—a software structure to define detailed and flexible layout generators explicitly. Using MESH, just a few lines of code describe complex layouts while all relations and design intents, such as element positions and routing styles, are captured through abstract commands. As a result, generators are created fast with less programming errors, and constructive algorithms can modify the generator structure directly
