Special Parametric Value (SPV)

 

MTT2D provides SPVs to help for users easily access and modify important design parameters

 

The list below introduces the characteristics of SPVs.

     SPVs always exist and are used internally.

     Each existing common SPV is initially placed in an input field of a dialog box.

     If the user does not check SPV name and enter a numeric value in the input field of dialog, the system refers to the numeric value.

     The users can create a new standard PV for the input field and its current value is the entered numeric value.

     If the user checks the SPV name and enters a numeric value in the input field of dialog, the entered numeric value becomes the current value of SPV.
