Allow changes to property values and input characteristics
Note: hdlram has been renamed. Use hdl.RAM instead.
release(OBJ) releases system resources (such as memory, file handles, and hardware connections) of System object™, OBJ. Releasing these resources allows all of the System object properties and input characteristics to be changed. After you call the release method on a System object, any subsequent calls to step or release that you make are not supported for code generation.
