When defining digital trace expressions, you can include any
combination of digital signals, buses, signal constants, bus
constants, digital operators, macros, and the Time sweep
variable.
The following rules apply:
• An arithmetic or logical operation between two bus
operands results in a bus value that is wide enough to
contain the result.
• An arithmetic or logical operation between a bus operand
and a signal operand results in a bus value.
The syntax for expressing a digital output variable or expression
is:
digital_output_variable
[;
display_name
]
or
digital_expression
[;
display_name
]
Use spaces or commas to
separate the output variables
you place in the Trace
Expressions list.
