Current Situation

HDLs currently only manage static system descriptions. Real world systems have moving parts and things that plug in and drop out.

A common failing in HDLs is to view instantiation with port-maps to be the only (right?) way to connect things. In real systems many cross-couplings occur as a system gets larger and more complicated.

Requirement

Handle dynamic addition and removal of entities. Connections can be made to any port or signal (not marked private).

Implementation details

As per C++ allow "new" and "delete" for instances.

Since the communication between components is through signals there is no intrinsic problem in reconfiguring resolution/communication in a running system - i.e. you don't have the dangling pointer issue of regular programming languages.

Dynamic instantiation covers the issue dynamic rewiring.

Code Examples
