Warning 5774, back annotation doesn't work

volain Aug 29, 2014 9:34 AM

After doing a gateswap in PADS Layout, when I do a back annotation in DxDesigner I get the following message for every trace swapped, e.g.:

pcb: Warning 5774: Bradbury pin $5I1053.IO_L19P_T3_34: Manually connect to old net DAC2_DATA14_P

This is the original state of the connection, not the swapped state.

Why won't DxDesigner accept the ECO? How can I fix this? The ECO file looks proper with the appropriate DELPIN and NET commands.

Can you post the design or a small example with the issue in it so that we can analyse it?

Here are my PADS Layout(test.zip) and DxDesigner files(test20140423093110.zip). I also noted that when doing the back annotation (from DxDesigner Link) I got the 5774 message for pins that WEREN'T swapped and didn't even appear in the ECO file. (Signal DAC2_DATA10_p, for example).
