Eagle 8.0.1 freezes after Autoroute completes

[bc]

I have a PC running windows 7

When I autoroute a board the routing completes and does a fairly decent job but  then the program freezes.

Originally I was having a problem that when I would edit the schematic, the autorouter would not work it said that the 

file in the autorouter did not match the board and would bring in information from previous manual routes that had been ripped up and saved.

I found that if saved the board with a new name that I could get it to pass the one edit that I had to do. 

Now when I autoroute the program crashes after it completes.  It does route to the 

It seems as if the autorouter is not clearing its cache or temp file, what ever it is using.

In the control panel I deleted all of the files except the Schematic and board (I have a backup).

This seemed to clear the autorouter.  But I cannot annotate the board and run the auto router again or the program will freeze.

I will autoroute a board as many as 100 times during the evaluation process.  

Is this normal? Is there a problem? What do I do?

Hello Ben,

I hope you're doing well. What you're describing is the classic result from not ending an autorouter job. When you run the autorouter you'll get few variants. At the bottom of the dialog you have the options to evaluate or end job.

If you click Evaluate, you can explore the result to make sure that that's the one you want. If you want to review the other variants, near the bottom right of the screen you'll see there is an autorouter icon, left click it. EAGLE will now tell you that there is additional variants saved and give you the options again, Evaluate to look at the other jobs or End job to keep the one you currently have.

The key point here is that when using the Autorouter you MUST click End Job in one of the two dialogs. Otherwise you'll start making changes and then these changes won't line up with the data EAGLE stored when it made the routing variants and you start seeing the errors you have described.

Please click accept as solution if my post fully resolves or you issue, or reply with additional details if the problem persists.

Best Regards,
