Exporting Libraries

Hi Tahakhan, I would try running the dbdoctor Database Check on your design firstly. I would also consider purging all unused padstacks. You will find this in the Padstack Modify options menu tab. Here there is a Purge button to purge all. Please also consider checking the option “No library dependencies” during export.

I have tried Dbdoctor without check on Regenerate Xnets. What does this term Regenerate Xnets means? The steps you mentioned above I normally follow them in my design but still this problem persists. It's maybe due to design complexity as layer count is above 70 but still there must be a solution for it.

An Xnet (Extended net) is a connection of two nets that are electrically connected through a passive discrete component, typically a resistor. If you have these in your design you will find them listed along with nets in Constraint Manager.   Xnets are required in electrical constraint applications to constrain a logical net in length or time from a driver to receiver through the discrete part. Nets and Xnets apply to the Electrical, Physical, and Spacing domains. You can constrain a net or Xnet by either referencing a CSet or setting overrides directly on the net or Xnet object. This Regenerate button forces the editor to regenerate all Xnets and differential pairs in the design database.

If you are willing to share your design with us to investigate, I will contact you directly to exchange. 

I sent you a friendship request message on forums with my email address. Please respond when possible. 

Thanks for the information and please check your inbox I have responded.
