Make autoroute work really hard

Gustav_M

Hi,

 

I would like the concept of the autorouter, but I have a problem when the PCB is complicated.

 

The autorouter works 30 sec max, and then 'gives up' on the last few wires. (Which are then impossible to fix!!!)

 

I would like to make the autorouter work until it is finished 100%. It is no problem to have the PC on for 24 hours.

 

Does anybody have experience with making the autorouter work? And is is explained in the documenttation how to setup the router?

 

Best Regards,

 

 

Gustav

    You can adjust the settings in the autorouter window for it to try

    harder. In the autorouter dialog, go to the Route tab. At the

    bottom-right you will see three text boxes, RipupLevel, RipupSteps and

    RipupTotal. The bigger you make these numbers, the harder Eagle tries to

    route a signal.

    I have followed your advice and increased the

    RipupLevel to 100 (was 10)

    RipupSteps to 1000 (was 100)

    RipupTotal to 1000 (was 100)

     

    This did not improve the result. The routing time was also about the same. I have also experimented with the "perferred directions" in the general tab, this changes the routing but the result is still not good enough.
