| Expanded ACT type names can contain characters like ''<'','' >', and '','' (among others). Instances can have names like ''a[3].b[5].z'', including the characters ''['', '']'', and ''.''. When exporting an ACT design to another format for use by a third-party tool, names with such characters in them can be potentially problematic. A good example of this is when exporting a SPICE netlist---different versions of SPICE have different syntactic restrictions. To handle this in a disciplined manner, the ACT library has the notion of a //mangled// name. A mangled name is generated by re-writing a user-specified list of special characters with an underscore and a number/character combination. This mapping is invertible, so a name can be unmangled as well. The set of characters to be mangled is specified in the ACT configuration option ''act.mangle_string'' (usually found in the global configuration file ''global.conf''). | Expanded ACT type names can contain characters like ''<'','' >'', and '','' (among others).
