can we have more vias in the connecting area without violating DRCs

i.e is there any limit for the max number of vias per unit area?
 

Re: adding vias

Hi,

No. However, newer process has via density requirement but usually it is too low a density that is a problem.

In the "past", it is a practise not to cover an area with maximum number of via as the huge number of vias will slow down the operation of the computer, make DRC/LVS run much slower and increase the disk size of the database. I think these problems do not exist anymore.

Regards,
Eng Han
