Symbolic Property: Property Number 18

The symbolic property is a property applied to cells which have a symbolic view associated. It does not appear in device library files, as all devices are essentially symbolic. It is not inherited by instances.
5 18 0/1 geometry_spec;
The third field is nonzero if the symbolic mode is active, and 0 if symbolic mode is inactive. The geometry_spec is a string of colon (yes colon!) separated CIF primitives for the symbolic representation, which can include L, B, P, W, and 94 (label) directives.

The symbolic property may be applied to subcircuit instances, in which case it will negate the effect of a symbolic property found in the instance master cell. In this case, the flag and geometry_spec are ignored and need not be provided. A subcircuit instance with this property would (in all cases) be displayed as expanded. Thus, it is possible in Xic to have different instances of the same subcircuit cell master display symbolically and expanded within the same containing cell.
