I ran two cases with same technology file, one is top level cell, another one is block level only.

However, when I ran the top level cell, there is  the following message output:

*** Calibre finished with Error: segmentation violation ***

 

 

Is it caused by the database too large? The database is about 95M.

Is there anyone can help me to solve it?

 

Thanks in advance!
