Deleting route Keepouts

Les Wong

Hi All:

When we delete route keepouts it takes a long time.

The same time as if we were manually deleting then in Allegro.

How can this be sped up ?

Thanks,

Les

  • Hi Les,

    As dave told first thing is to make the shapes disbled so that it will not update shapes online which will be helpful for me most of times to improve tool performance. 2nd thing is DRC's should not be more than 5000 which could lead to slow up tool. Also subclass used in constraint regions should be only signal/plane layers not for all. 3rd thing delete unnececessary shapes/ dxf which will not be used to free up board memory

    if all the above wont work go with performance advisor which will suggest the reasons to improve allegro performance

    Regards,
