To add a bus expression
1
In the Add Trace dialog box, in the Functions and Macros
list, select Digital Operators and Functions.
2
Click the
{ } entry.
3
In the Simulation Output Variables list, click the signals in
high-order to low-order sequence.
4
If you want to label the bus with a name that is different
from the default:
a
Click in the Trace Expression text box after the last
character in the bus name.
b
Type ;
display_name where display_name is the
name of the label.
5
If you want to set the radix to something different from the
default:
a
Click in the Trace Expression text box after the last
character in the expression.
b
Type one of the following where
radix is a value from
the table on page 14-26

radix value).
Examples:
{Q2,Q1,Q0};A;O
specifies a 3-
bit bus whose most si
g
nificant bit
is Q2. Probe labels the plot A,
and values appear in octal
notation.
{a3,a2,a1,a0};;d
specifies a
4-bit bus. On the Probe plot,
values appear in decimal
notation. Since no display name
is specified, Probe uses the
si
g
nal list as a label.
{a[3:0]}
is equivalent to
{a3,a2,a1,a0}
