Aspen model analysis fee

What are the input rules for the constraints in Aspen simulation optimization? For example, in Model Analysis Tools/Constraint/C-1/Input/Spec, the specification can be set to “less than or equal to”, but what information needs to be entered in the three rows that follow? I see that some of the input statements contain DLOG – what does that mean?
The specification refers to the variables you define in the define section; the second field is for entering a number that is less than or equal to a certain value, and the third field is for the tolerance. Dlog is just the log symbol
