I am looking into a reference design which was probably done using Orcad. I am using KiCAD for my design.

In the reference design, there are schematic symbols like >> and <<. According to this guide, they seem to be 'off-page connector'. The guide says

"Off-page connectors are used to connect signals to like-named off-page connectors and hierarchical ports on other schematic pages within the same schematic folder. "

So, what is the off-page connector (>> or <<) equivalent at KiCAD? Global label or hierarchical connector?

Kicad global connector is valid for whole schema project (all sheets), hierarchical port provides connector on hierarchical sheet. It makes significant difference if your hierarchical sheet is reused more times or you have own library of sheets. In this case you can connect hierarchical connector on project sheet where hierarchical sheet(s) is/are placed. It's analogous to programming: global variable vs. procedure with arguments. You should be able use proper connector when you understand topology of your Orcad scheme.

  • \$\begingroup\$ Thanks. Here are examples of the usage on >> and << on a multisheet schematic The source is used in a different sheet and also in this [sheet](imgur.com/WlbPWEJ ) So, are they essentially hierarchical label in KiCAD? \$\endgroup\$ – nad Aug 19 '14 at 18:08
  • \$\begingroup\$ No, I'd say it's typical global connector. It's just name of MCU pin which is valid everywhere. I'm using it this way too (to provide MCU pin names as global labels). \$\endgroup\$ – TMa Aug 19 '14 at 19:54
