Buses to a Probe Plot
A set of up to 32 signals can be evaluated and displayed as a bus
even if the selected signals were not originally a bus. This is
done by following the same procedure already given for adding
digital signals to the plot. However, when adding a bus, be sure
to enclose the list of signals in braces: { }.
{ Q3 Q2 Q1 Q2 }
The complete syntax is as follows:
{ signal_list }
[
;
[
display_name
][
; radix
]]
or
{ bus_prefix
[
msb : lsb
]
}
[;[
display_name
][
; radix
]]
Valid entries for radix are shown in the following table.
This placeholder... Means this...
signal_list
comma- or space-separated list of up to 32
digital node names in sequence from high
order to low order
bus_prefix
[
msb
:
lsb
] alternate way to express up to 32 signals in
the bus
display_name
(optional)
text string (name) that you want Probe to
use to label the bus on the plot instead of
using the default output variable notation
radix
(optional)
numbering system that you want to display
bus values in
For this numbering system... Use this notation...
Binary (base 2) B
Decimal (base 10) D
Hexadecimal (base 16) H or X
Octal (base 8) O (the letter)
