Auto Routing issue

EverLasting

 Hi everybody

I'm a beginner in orcad pcb desighn,and i have created a circuit using  orcad capture V16.5 sw then trnasfer it to pcb editor and when i have made autorouter,

i found that some tracks are crossed, and they shouldn't be and i don't know why it's crossed,

is it an issue in autorouting?

or i'm doing some thing wrong

or there any configurations befor using auto routing

so pls help

     There are some circumstances when the autorouter is stopped before the proper clean-up passes are run where you will see intersections.
    Can you please give a detailed list of how you started the autorouter from your design?

     Ok, its been a few years since I had the opportunity to use this.

     But, "clean" and "critic" are two commands you may want to run after the route.  Clean works differently than the normal route routine and multiple passes can be run.

     

    Critic removes all DRC proximity and net short errors before you bring the layout back to Orcad in a single pass.
