Chapter 1: Agilent Technologies 16712A 128K Sample Logic Analyzer
Importing Netlist and ASCII Files
•
waveforms and bus values (where shown) invert in the Waveform Display
tool
•
"1" and "0" values flip in the Listing Display tool
Changing the label polarity does not change these things:
•
Edge definitions for clock setup and
edge terms
•
Symbol definitions for the logic analyzer
The default polarity for all labels is positive (+). The various display
tools, in particular the Waveform Display tool, all show logical values
and are affected by polarity changes.
NOTE:
Negative logic is rare in circuits. The main exception at this time is RAMBUS.
To reorder bits in a label
In cases where buses in the device under test haven't been probed with
consecutive logic analyzer channels, you can reorder the bits in a label.
1. In the Format tab, select the label button whose bits you want to reorder.
2. Choose
Reorder bits
.
3. In the Change Bit Order dialog:
•
To reorder the bits individually, enter the bit that the probe channel
should be mapped to.
•
To swap the high and low order bytes or words, select the button
Big
Endian to Little Endian
at the bottom of the dialog.
•
To return to sequentially ordered bits, select the button
Default Order
at the bottom of the dialog.
4. Select the
OK
button.
The label now shows an "R" to indicate that the assigned bit has been
reordered.
