General Description: How do I specify properties for nodes in a schematic that are not at the top level of the schematic?
If the node is on the top-level of the schematic, the name given to the node in the schematic can be used in the control file. However, if the node is down some levels in the hierarchy, then the path name of the signal should be used in the control file. Note, however, that if you examine the *.ph1 file or the *.ann file to see if the node has been kept, the name of the node may be different depending on the length of the hierarchical path. Long names are shortened and the *.xrf file states what is the new, shorter hierarchical name.
In the example below, it is desirable to keep nodes in the schematic that are in a block called INCREMENT. The control file would be (please note the spacing):
