 This module provides the following myhdl objects:
-downrange -- function that returns a downward range
-Error -- myhdl Error exception
-bin -- returns a binary string representation.
-       The optional width specifies the desired string
-       width: padding of the sign-bit is used.
+instances -- function that returns instances in a generator function
+             these are all generators in the local namespace
+processes -- function that returns processes in a generator function
+             these are generators obtained by calling local generator functions
