  • The list of nodes for the -from option is preferably a list of valid startpoints. A valid startpoint is a clock, an input or inout port, or the clock pin of a sequential element like a register or RAM. Using a node that is not a valid startpoint causes path segmentation. The concept of path segmentation is explained in Path Segmentation.
  • Multiple elements can be provided.
