“…They are a special kind of constraint for specifying the floorplan and sometimes the routing of analog blocks in a knowledge-based way. The underlying method of template description, its implementation, and solving strategy (e.g., by evolutionary approaches) is the subject of research [26][27][28][29][30]. As an example, the framework AIDA [13] utilizes templates and combines many academic works, from optimization algorithms to layout automation used for various designs.…”

Various analog design automation attempts have addressed the shortcomings of the still largely manual and, thus, inefficient and risky analog design approach. These methods can roughly be divided into synthesis and procedural generation. An important key aspect has, however, rarely been considered: usability. While synthesis requires sophisticated constraints, procedural generators require expert programmers. Both prevent users from adopting the respective method. Thus, we propose a new approach to automatically create procedural generators in a user-driven way. First, analog generators, which also create symbols and layouts, are utilized during schematic entry to encapsulate common analog building blocks. Second, automatic code creation builds a hierarchical generator for all views with the schematic as input. Third, the approach links the building block generators with the layout through an object-oriented template library that is accessible through generator parameters, allowing the user to control the arrangement. No programming is required to reach this state. We believe that our approach will significantly ease the transition of analog designers to procedural generation. At the same time, the templates allow for a “bridge” to open frameworks and synthesis approaches so that the methodologies can be both better spread and combined. This way, comprehensive frameworks of both synthesis-based and procedural-based analog automation methods can be built in a user-driven way, and designers are enabled to gain early layout insight and ease IP reusability.

“…Adapted from [53]. Chin and Pan et al (2013-15) [62][63] intended to fully preserve the routing behavior of the legacy design by using a constrained Delaunay triangulation (CDT) algorithm[64], which represents the correlation between routing and placement into a planar straight line graph. First, placement and routing paths are decomposed with a set of triangles, as illustrated in Fig.6(b) for a layout diagram with two blocks and one routing path in Fig.6(a).…”
