Creating New Display Tables for Master and Sub Comparators
This section shows how to add new display tables for Master or Sub Comparators. It assumes that you
are familiar with the Master and Sub device bit interaction as described in the previous section.
Sub Comparator Display Table
To add a tab for a new device to properly display the four Sub Comparators in our “Virtual Comparator”
example system from Page 167,
• Right-click on one of the existing tabs at the top of the Display Table window
• Click on Append New Table. The following window will be displayed.
• Type in a new Tab Name such as “Sub Comparator ”.
• Select the number of status Input Bits that this new device will possess.
In addition to the 5 Input Bits of the predefined Comparator device, we will use an additional
status bit to hold the Vote bit that will be inherited from the Master Comparator. So in this case,
the number of Input Bits should be set to 6.
• Click on OK to close this window. A new blank display table will be entered with 6 bits.
States Tab
• Right-click anywhere on the States Table for this new “Sub Comparator” device, then click on
Append to add lines for additional states.
• Modify each state line in the States Table to satisfy the display requirements for this system’s
“Virtual Comparator. As shown in the following, a bright Green “Vote” will be displayed only
when the Sub Comparator has voted (the Vote bit is set) and the Master Comparator has voted
(the Master bit is set).
