bus
A named vector signal with a type and bounds drawn as a composite line on a block diagram.
See also net and bundle.
—C—
case box
A named object which represents a CASE statement on a flow chart or ASM chart. When used
for decoding action logic each Case has an associated End Case object. A case box has one input
flow and one or more output flows corresponding to the possible values for an evaluated CASE
expression. See also action box, decision box, if decode box and wait box.
child
A view instantiated below its parent in the design hierarchy. A component or block on a block
diagram or IBD view typically has a child design unit view which may be another block diagram,
IBD view, state diagram, flow chart, truth table or a HDL text view. Also used for the embedded
view representing a hierarchical state or “hierarchical state box” on page 450 in a hierarchical
state machine or a hierarchical action box in a hierarchical flow chart or ASM chart.
clocked signal
A signal in a state machine whose value is assigned to an internal signal by the clocked process.
This internal signal is continuously assigned to the real output signal. No default value need be
specified. Typically used for an internal counter whose value is also required as an output. See
also combinatorial signal and registered signal.
clocking
The timing aspects of behavior can be asynchronous or synchronous (explicitly clocked).
clock point
An object on an ASM chart which displays the clock signal name and condition. See also enable
point and reset point.
clone window
A duplicate view of a graphical editor window. All select, highlighting and edit operations are
made in both windows. However, you can display different parts of the diagram or table in each
window.
combinatorial signal
A signal in a state machine whose value is directly assigned to the output port. See also clocked
signal and registered signal.
comment graphics
Annotation graphics which can be used for illustration on a block diagram, state diagram, flow
chart or symbol.
