The group tabs can be organized via drag-n-drop. Click and hold the left mouse button on a group's tab until it is "picked up". Move the mouse vertically and the green insertion line will move. Release the left mouse button when the insertion line is at the new position.

The tab area width can be resized if needed. Move the mouse over the right edge of the tab area and the cursor changes to the resize icon...

Likewise, the tab name-section can be resized to accommodate longer names. Move the mouse over the right edge of the group name section. The cursor changes to the resize icon...

Click the left mouse button to add/remove channels in the active group. Dragging the mouse across the channel selection area adds/removes multiple channels.

Each channel is added as the group's most significant bit. Therefore, dragging from left-to-right in a pod area adds the channels in ascending bit-order. Dragging from right-to-left adds the channels in descending bit-order. The bit-order can be edited in the Bit-Order area described next.

If a channel is not used in any channel group, the GoLogic software assumes it is not connected and ignores any input signals. These unconnected channels are ignored at run-time, cannot trigger the GoLogic, and cannot detect transitions.

For active channels used in at least one channel group, you can either allow each channel to detect transitions or to ignore transitions...
 

• "Delete all groups" removes all groups. However, one tab always exists in the window. Using this action leaves a single tab with zero channels and the default name "group1".
• "Delete empty groups" removes all groups that have no channels.
• "All groups use ascending bit-order" sorts all groups with the ascending bit-order.
• "All groups use descending bit-order" sorts all groups with the descending bit-order.

• "Show active-low line" displays a line over a group’s name which emphasizes the signal's meaning. This is a common naming convention used in electronics. When a zero is present on the signal, then it is active.
• "Use inverted logic" interprets samples below the threshold voltage as one while samples above the threshold are zero. Standard logic displays values above the threshold voltage as one while samples below the threshold are zero. This option inverts each bit when the group is displayed in the WaveForm and Numeric windows.
• "Remove all channels" deletes all channels in the group.
• "Sort ascending" makes the smallest channel number the least significant bit and the largest channel number the most significant bit. Channel A00 is the smallest channel number in the GoLogic. The clock channels are the largest channel numbers.
• "Sort descending" makes the largest channel number the least significant bit and the smallest  channel number the most significant bit.
• "Reverse bit-order" makes the least significant bit the most significant bit and vice versa.

Each group name can be up to 127 characters long. Using names less than 30 characters is recommended because long names may be truncated if they do not fit in an area.

The past 10 group names is listed in the control's drop down. Select previously used group names using the drop-down list button.

A range of channels is defined using the dash character. For example…

All pod A channels are used in the above example. Channel A00 is the least significant bit in the group while channel A15 is the most significant bit.

In the previous example, all pod A channels are used plus channel B07. Channel A00 is the least significant bit in the group while channel B07 is the most significant bit.

Be aware that colors can also be set independently in each WaveForm line or Numeric column without affecting the other windows. If all windows use the same color to display a channel group, then that color appears in the Channel Groups tab color list. If any WaveForm lines or Numeric columns display the channel group using two or more unique colors, then the default gray appears in the Channel Groups tab color list. The group's color-swatch is also hidden.

The 9 "basic" colors automatically adjust to the pale or dark background colors. The software uses pale versions of these colors when a dark background is used. Likewise, the software uses dark versions when a pale background is used. This feature is very convenient if you open projects file from someone using a different background color.

However, custom colors do NOT adjust to pale or dark background colors. Opening a project file with custom colors may require the channel group colors to be adjusted. Alternatively, you can change your background color to something more compatible with the custom group colors.

Click the "Symbol Table..." button to load a symbol table file into the channel group. Once loaded, the symbols can be displayed in place of numeric values in the WaveForm, Numeric, and PlugIn window. More importantly, the symbols can be used in the TriggerForms rather than entering numeric values.

The Bit-order area is identical for all channel display modes and is described earlier in this chapter.

The up, down, left, and right arrow keys navigate to any field in the setup area. The active setup field is outlined with a black rectangle. Press the "return" key to edit the active setup field, and press either "escape" or "return" to exit edit-mode.
 

Click the left mouse button to add/remove channels in each group. Dragging the mouse across the channel selection area adds/removes multiple channels.

Each channel is added as the group's most significant bit. Therefore, dragging from left-to-right adds the channels in ascending bit-order. Dragging from right-to-left adds the channels in descending bit-order. The bit-order can be edited in the Bit-Order area described earlier.
 

Unavailable channels are normally hidden so that no virtual channels exist in the tab. For example, a GoLogic-36 only displays pods A and B which are always physically available. However, loading a project captured from a GoLogic-72 causes pods C and D to be displayed. All channels in these pods are physically unavailable to the GoLogic-36 hardware, so these virtual channels are displayed in faded colors. You can define channel groups on these channels to view the 72-channel data, but you cannot trigger on these channels. The threshold buttons, transition detectors, and activity indicators on virtual channels are also disabled.

• An unlimited number of channel groups can be defined. The first channel group cannot be deleted, so at least one group always exists.
• Each channel group can contain from 1 to 64 channels (64-bit buses are supported).
• Each channel group name can have up to 127 characters.
• The channels can can use any bit-order within a group. For example, channel CA0 can be the most significant bit in a group while channel B15 can be the least significant bit.
• Empty channel groups contain no channels. Empty channel groups cannot be used in the TriggerForms and are not displayed in the WaveForm, Numeric, or PlugIn windows. We recommend deleting empty channel groups.
• Channels can be used in more than one channel group. However, we do not recommend this practice because it can cause confusion in the TriggerForms.
• Groups containing virtual channels cannot be used in the TriggerForms, but can be used to view trace data.
