Important General Note:

• Export PDF to download, if vivado revision is changed!

• Designate all graphics and pictures with a number and a description, Use "Scroll Title" macro

  • Use "Scroll Title" macro for pictures and table labels. Figure number must be set manually at the moment (automatically enumeration is planned by scrollPDF)

    • Figure template (note: inner scroll ignore/only only with drawIO object):
