+# 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.
