OTcl Linkage</H1><P>is an object oriented simulator,written in C++, with an OTcl interpreter as a frontend.The simulator supports a class hierarchy in C++(also called the compiled hierarchy in this document),and a similar class hierarchy within the OTcl interpreter(also called the interpreted hierarchy in this document).The two hierarchies are closely related to each other;from the user's perspective,there is a one-to-one correspondencebetween a class in the interpreted hierarchyand one in the compiled hierarchy.The root of this hierarchy is the class TclObject.Users create new simulator objects through the interpreter;these objects are instantiated within the interpreter, and are closely mirrored by a corresponding objectin the compiled hierarchy.The interpreted class hierarchy is automatically established throughmethods defined in the class TclClass.user instantiated objects are mirrored through methodsdefined in the class TclObject.There are other hierarchies in the C++ code and OTcl scripts;these other hierarchies are not mirrored in the manner of TclObject.<P><BR><HR><!--Table of Child-Links--><A NAME="CHILD_LINKS"><STRONG>Subsections</STRONG></A><UL><LI><A
