# Read Side Files and Annotate Data
# @description
# Parse a NanoTime report file and display all paths in a custom widget.
# Timing values are annotated in the schematic view.
# Individual paths can be displayed in the Cone window.
#
# Usage:
#
# After loading a NanoTime report, the tab 'NanoTime' shows the original
# report file, as well as the list of report items found in the file.
# Clicking a report item scrolls the report file to the corresponding
# position and highlights the path nodes of the report item.
#
# The button 'Load Cone' loads the path nodes of the selected report item
# into StarVision's/SpiceVision's 'Cone window'.
# You can annotate the path with attribute values by checking some check
# boxes in the 'Show' section.
#
# The button 'Load Mem' loads the path nodes into the 'Mem window'.
#
# Checking 'Show Only Violating Items' updates the items list to only
# show report items which violate slack constraints; unchecking it will
# display all items.
