Path Continuation By Segment Selection

The path continuation display program gives the designer an effective tool which allows him to continue from the end of a path diagnosed by Timing Analysis.

When a block index is given to the continuation programs, they search for blocks with names the same as the given block but without any suffix code.

From the "pseudo-continuation" block a set of forward paths is traced and displayed on the video display unit with full information concerning slack and arrival time values. (Although we trace all paths for this procedure, only the forward cone is displayed on the video display unit in a manner similar to the ALD (Automated Logic Diagram) formats, but much faster.)

The user is presented with the display and a list of the paths and allowed to select a path segment for addition to the current chain (even though they are not directly connected).

The procedure then extracts the forward paths from the end of the extended chain, the user selects a continuation, and so on.
