ATPG constraints with this temporal function option. The
Temporal constraints cannot be used with
Note sequence to satisfy the temporal constraints with the previous generated test sequence. Refer to the Set Self Initialization command for more information.
The Add Atpg Functions command also lets you add ATPG functions to a net. Thus, if the circuit structure changes and the ATPG functions specified on the net pathnames do not change, you do not have to identify the instance and the pin on which the ATPG functions have to be applied. If any ATPG function is added to the net, the equivalent pin is found first and the function is added to that pin instead. Therefore, the Report Atpg Function command may not show the net pathname specified.
Arguments
∙function_name
A required string that specifies the name of the ATPG function that you are creating. You can use this function_name as an argument to the Add Atpg Constraints command.
∙type
A required argument specifying the operation that the function performs on the selected objects. The choices for the type argument, from which you can select only one, are as follows:
And — The output of the function is the same as for a standard AND gate.
Or — The output of the function is the same as for a standard OR gate.
Equiv — The output of the function is a high state (1) if all its inputs are at a low state (0), or if all its inputs are at a high state (1). So, the function’s output is a low state if there is at least one input at a low state and at least one input at a high state.
