I am creating a library component for KiCAD using a convenient online app at: http://kicad.rohrbacher.net/quicklib.php. The component I am making is the Microchip PIC24EP512GU814 in LQFP http://www.microchip.com/wwwproducts/Devices.aspx?dDocName=en554337.
The app asks me to assign a type to each pin. The types avilable are:
Input Output Bidir Tri-state Passive Unspecified Power Input Power Output Open Collector Open Emitter
I must now assign one of these types to the
My best guess is that
VDD should be assigned as
Power Input. Would
VSS also be considered as a power input?
VDD is analogous to
VEE), I could classify
VDD as an
Open Collector (and
Open Emitter). However I'm not sure if
VSS can be considered as "open" for an IC.
VSS be mapped to?
