Abstract
An example method of generating a control and data flow graph for hardware description language (HDL) code specifying a circuit design is described. The method includes traversing an abstract syntax tree (AST) representation of the HDL code having a plurality of modules on a module-by-module basis. The method further includes adding an execution unit to the control and data flow graph for each module having concurrent paths. Each execution unit includes nodes in the control and data flow graph. The nodes include a loopback sink that merges the concurrent paths and a loopback source that receives feedback from the loopback sink and propagates the feedback to the concurrent paths.
