Hi ,

 

I am trying write drc code to check the maximum number of pad rows per die side.

The  main problwm here is that there is not minimum limit on nmuber of pads  to form a row, even a singe pad can form a row.  And all the pads have  to abide by the minimum spacing value.

Thsi get tricky when we  have 45 degree edges at the die corner so i can assume a max lookout  region perside to  chekc for thr number of pad rows.

Do you have any ideas on how this check can be coded ?

 

Thanks

Lucky
