# A vector of source pins which might represent a bank of physical pins. Unlike
# IntSourcePin, each source pin in VectorIntSourcePin can only connect to a
# single sink pin. VectorIntSourcePin has the same definition as IntSourcePin
# right now, but will likely be implemented differently in the future.
# VectorIntSourcePin is defined as its own separate type to differentiate it
# from IntSourcePin and make it clear to the user how it should be interpreted
# and used.
