Hi Austin, There are only a couple causes for the ref des values to change and parts getting ripped up in Allegro - 1. You've deleted the package folder files. 2. You don't select the preserve option in Export Physical. 3. Several part names/properties in DEHDL have changed. Short of these, ref des values should be maintained. This is why I've asked for a testcase - so we can examine the issue as it indeed is very odd.

Hi Mark, THANK YOU! That worked great. It was only 8 pages, so only 5 minutes to do. All the components that shouldn't have been ripped up, now aren't! Back on my merry way again ;-) The question really, for Cadence that is, is why on earth does it redo the REFDESs in the first place? And, even when it redoes them, why does it rip-up components that are still in the design, and had no change except the REFDES...and it doesn't do that to all of them, only some of them.

Austin, We usually replace $LOCATION with LOCATION for every ref des if this happens. It hard locates all ref des instead of $LOCATION (Soft location) Unfortunately, you have to do find / replace on each page. 1. Start the Project Manager and open your project. 2. Start Design Entry 3. In the Concept Console Window type: find $location Note: find $LOCATION can be copied, then Ctrl V to paste in each page. Paste does not work? A group will be created and the number of occurrences found on that page, will be listed in the Console Window along with the group name. See example below: 4. Either Type: change "group name" Enter appropriate group name. (i.e.) change A in cmmand window (OR) *Select Group / Text Change [A]* pull-down menu Note: All members of the group should be temporarily hilited. Note: If group selections are "grayed out", then select the correct group in the group tool bar. (below the schematic) 5. Next, Rt Click and select Editor (see below) or typeCtrl+E. The window seen below will appear. *Note:* This will start theText Editor tool and display a listing of ALL group members... 6. From the pull-downs, select Edit / Replace. A window will appear. 7. On the Find line enter $LOCATION (This is case sensitive.) On the Replace line enter LOCATION Select Replace All. *Note:*When complete select File->Savein the text editor. You may then close the Text Editor. 8. In Concept select File->Save to write the schematic page. 9. Repeat for all schematic pages Regards, Mark On 4/18/2011 11:25 PM, allegrolist@xxxxxxxxxxxx wrote: > Hi Jerry, > > Thanks for the help. I don't have a small test case.
