Detailed Description

Storage type for an entire expression / subexpression tree.

Expression type over a struct.

Each expression node has left and right children (unless it is a leaf) and an operation. The idea being that if the children are primaries, then we extract their value, perform the operation described in this node, and return up the expression tree, or recurse into a child expression as appropriate.

Todo:: This part of the tree (and sub parts) is currently quite messy. When I come to actually using this for something practicle, I may end up re-writing it. That will be post the first "release" though.

The documentation for this struct was generated from the following file:

src/verilog_ast.h
