What is ArchFP?

ArchFP is a simple, easy to use, floorplanning tool targeted towards prototyping of pre-RTL CMP design concepts. As such, it is complementary to traditional floorplanners that are more appropriate later in the design cycle. An ArchFP floorplan is specified using a model similar to that supported by GUI toolkits such as Java Swing and Windows Presentation Foundation. The user designs the floorplan in C++ by creating a hierarchy of HW components placed within containers, called Layout Managers (LMs), which provide a variety of layout algorithms. Current LMs include a generalized grid LM, one that supports geographic hints for component placement, and an LM used to import subcomponents. ArchFP is easy to extend with additional LMs that leverage the built-in layout algorithms to support more specific design elements such as NoC configurations, cache partitioning strategies, SIMD design, etc. ArchFP produces and consumes HotSpot floorplan format files.
