Groups
A group is defined as a set of logical channels. Grouping functions is especially
useful depending on the DUT (Device Under Test). Several channels are
sometimes used with the same output level and data format. In this case, handling
multiple channels as one group is a useful method.
The number of logical channels that the system can accept is determined by the
mainframe (32 for DTG5078, 8 for DTG5274, and 8 for DTG5334). In the
Master-Slave operation mode, the number increases with the number of
mainframes. The number of groups depends on how many groups the user divides
into the logical channels. The total number of logical channels in each group cannot
exceed the number of logical channels that the system can accept. By default, every
logical channel is divided into an eight-channel group. To add a new group, you
have to delete some groups or decrease the number of logical channels in a group
to secure the logical channels required for the new group.
To create, delete, rename or resize a group, use the Channel Group window.
Blocks
A block is defined as a set of groups that consist of logical channels. The block is
an elementary data of signal output. To specify the block length, use the block size
located in the Blocks window. The block size represents the pattern data length, or
vector length. The block width is the sum of bit width in the group to which it
belongs, that is, the total number of logical channels.
By default, one block named Block1, whose size is 1000, is created.
Creating multiple blocks enables you to generate repetitive signal outputs by the
blocks or sequential outputs with jumps. Even if two or more blocks exist in the
system, only one method can be used for either grouping or channel assignment.
To create, rename, or resize a block, use the Blocks window.
Use the Data-Listing or Data-Waveform window to edit values (0 and 1) in the
individual pattern data. Editing is possible by the block unit. To specify the block
to be edited, you can use
Select Block...
from the Edit menu of the Data-Listing or
Data-Waveform window, or use
View Data-Listing
or
View Data-Waveform
from the Edit menu of the Blocks window.
To set the voltage output setting parameter, use the Level window. To set the
timing output setting parameter, use the Timing window. Both parameters can be
set by the channel unit (except for clock frequency), but not by the block unit.
Sequence
A sequence consists of blocks and subsequences. As the subsequence elements,
one or more block names and the repetition of the blocks are defined. Using a
sequence, you can output complex signals by defining blocks, number of times the
subsequence repeats, and jump conditions.
