NGDBuild - Is there any option to bypass unmatched UCF constraints errors?

Description

I am running an incomplete design with a complete UCF (a UCF contains all constraints for the complete design).

NGDBuild gives the following errors on constraints in which the objects do not exist in the incomplete design.

Error: Constraintsystem: 58

Error: Constraintsystem: 59

Is there any option to bypass this type of error rather than manually removing/commenting out the constraints?

Solution

The -aul and -aut options are available with NGDBuild to bypass this type of error on LOC and TNM/TNM_NET constraints. 

However, for other constraints such as NET TIG or AREA GROUP, you must remove/comment out the constraints in the UCF manually.
