""" myhdl package initialization.
This module provides the following myhdl objects:
Simulation -- simulation class
StopStimulation -- exception that stops a simulation
now -- function that returns the current time
Signal -- class to model hardware signals
delay -- callable to model delay in a yield statement
posedge -- callable to model a rising edge on a signal in a yield statement
negedge -- callable to model a falling edge on a signal in a yield statement
join -- callable to join clauses in a yield statement
intbv -- mutable integer class with bit vector facilities
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.
concat -- function to concat ints, bitstrings, bools, intbvs, Signals
-- returns an intbv
instances -- function that returns all instances defined in a function
always_comb -- function that returns an input-sensitive generator
enum -- function that returns an enumeration type
traceSignals -- function that enables signal tracing in a VCD file
