Pin placement does not show up

Hi Cadence Forum,

I have a large amount of pins 4000+, and I want to generate pins and attach them to the corresponding nets automatically. I want to use Place -> Pin Placement, but for some reason there is no pop-up window... I have also tried to generate all the pins and attach them by using Place -> Analog -> Adjust Cell Pins but without success (Virtuoso crashes); normally this worked with other designs. The latter approach could be performed with smaller design, but with larger design I am getting problems.

I am using IC6.1.8.

Thanks

Kind regards,

Nicolas
