Specctra Autorouting with do file with delay constraints

[Neha Anu]

Hi all,

I'm currently using the Allegro PCB Router tool for autoruting the boards with do file.I'm trying to autoroute the a bus that are given constraints of relative propagation delay and propagation delay.While autorouting the some of the signals are not obeying the rules and some are left unrouted.Can anyone pls xplain is there any option to autoroute all the selected signals in a bus when both the constraints like propagation delay and relative propagation delay are given??

Thanks,
Neha.
