迭代组
当测试组不能再找到一个有效MV进行阶跃时，其将标记为迭代完成并增加STGITERC计数。如果完成迭代次数大于或等于需求迭代数（STGITER），则测试组标记为已完成。某测试组完成后STGCOMP标签将被设置为1，并且测试组请求标签将被设置为SUSPEND(挂起)。当用户将测试组放回TEST(测试)或TEST NO-PULSE模式时， STGCOMP标签将复位。其允许工程师使用CCF计算来建立一些基本的测试调度。例如，当第一个测试组完成需求迭代数量时，工程师可以建立一个计算将所有测试组纳入控制中。
组织测试组进行有效测试
测试组设计应最大限度地同时并行阶跃测试。当测试组处于TEST模式时，其在一时间内仅可进行一个MV的阶跃。如果两个MVs不相关（即它们不影响相同的CV），那么它们可以同时做阶跃测试而不会产生相关数据。这是将MVs放在单独测试组的充分理由。
当CV在测试范围外时，测试应用将使用测试组中的所有MVs最优化解决这一问题。此外，CV所属的所有测试组也将用于解决此问题。
如果测试组中某个CV不受MVs的影响，那么该CV不应该在该测试组中。
如果你遵循这些一般准则，那么你可以实现以下好处：
•在任一时刻MV可被组织到测试组中实现同时测试数量最大化。
•CVs可以被分配到这些组中来触发相应的纠正行为。

Group iterations
When the group can no longer find a valid MV to step then it will mark the iteration as complete and increment the STGITERC counter. If the number of iterations completed is greater or equal to the number of iterations requested (STGITER) then the group is marked completed. Upon completion of a group the STGCOMP flag is set to one and the group request flag is set to SUSPEND. When the user puts the group back into TEST or TEST NO-PULSE then the STGCOMP flag is reset. This allows the engineer to set up some basic test scheduling using ccf calculations. For example the engineer could set up a calculation that puts all test groups into CONTROL once the first test group finishes its requested number of iterations.
Organizing test groups for effective testing
Test groups should be designed to maximize parallel stepping. A group that is in TEST mode will only have one MV stepping at a time. If two MVs are unrelated (that is, they do not impact the same CVs), then they may be stepped simultaneously without generating correlated data. This is sufficient reason to put the MVs in separate test groups.
When a CV goes outside of test limits, the tester application will react to fix the problem by using all of the MVs from the TEST group in an optimal matter. Moreover, all of the test groups to which the CV belongs will be used to correct the problem.
If a CV is not impacted by the MVs of a test group, then the CV should not be in that test group.
If you follow these general guidelines, then you can realize the following benefits:
•MVs can be organized into groups to maximize the amount of simultaneous testing at any given time.
•CVs can be assigned to these groups to trigger the appropriate corrective behavior.
