Sorting - Sort by pin interfaces will sort the pin sequence by assigned pin interface  names.  This is very useful for the partitioning of symbol sets on ASIC's where specific sections are assigned different symbol or hetero id's.  Move the Symbol Wizard spread sheet to display the Interface section.    After sorting, the pins will appear in the requested format: 

• By Pin Interface, with a secondary sort by Pin Name, and a third sort by Bus Low to High.
• By Pin Interface, with a secondary sort by Pin Name, and a third sort by Bus High to Low.
