Updating from a higher level oe to a lower level
Buried nodes in lower-level sources are handled as follows: Lower-level nodes that do not fanout are propagated to the higher-level source and become dangling nodes.Optimization may remove dangling nodes from the lower-level source.The main role of the top level management is summarized as follows :- The Middle Level Management consists of the Departmental Heads (HOD), Branch Managers, and the Junior Executives.The Departmental heads are Finance Managers, Purchase Managers, etc.The Chief Executive Officer is also called General Manager (GM) or Managing Director (MD) or President.The Board of Directors are the representatives of the Shareholders, i.e.You do not have to declare all output pins as ports.
The Junior Executives are Assistant Finance Managers, Assistant Purchase Managers, etc.
Combinational nodes in a lower-level source become collapsible nodes in the higher-level source.
Registered nodes are preserved with hierarchical names assigned to them.
To instantiate an ABEL-HDL source file, you need to do the following: In the lower-level source: (optional) Hierarchy declarations are not required when instantiating an ABEL-HDL source in a schematic.
For instructions on instantiating lower-level source in schematics, refer to your schematic reference.
