Dear all,
Currently when I finished astro routing on my design (50k gate, without memory, only 30% utilization), the violation is unbelievable large:there are totally 200k violations about "Wrong-way wire on via" even if I set the cost of non-preferred direction routing to a very high value.
Has anybody met with similar situations before or how can I deal with so many violations?

Thanks in advance!!

astro routing violation

Hi eexuke,

Check out the directiion of your standard cells pins.In case if they are in the non-preferred direction. Try to turnoff the switch wrongWayNoVia to 0 or try to change the direction of the pins.
