semiconductor integrated circuit. The interactive graphic
editing system includes an attribute data base storage unit
and an editing unit comprising a pattern figure editing unit,
an attribute setting unit, and a processing unit. More
particularly, the attribute data base storage unit stores
attributes of various editing objects necessary for simulating
characteristics of the designed semiconductor integrated
circuit, and the editing unit includes means for enabling the
editing objects to be manipulated and for fetching data from
the attribute data base storage unit to determine whether the
attributes of the selected editing objects can be set and to
allow a user to select the attributes of the editing objects.
Claims 9 and 15 are illustrative of the claimed
invention, and they read as follows:
9. An interactive graphic editing system for designing
a semiconductor integrated circuit comprising:
an attribute data base storage unit in which attributes
of various editing objects necessary for simulating
characteristics of the semiconductor integrated circuit being
designed are stored, and
editing means for enabling the editing objects to be
manipulated and for fetching data from the attribute data base
storage unit on selection of the editing objects to determine
whether or not the attributes for the selected editing objects
can be set and, if the attributes can be set, allowing a user
