Hi,
i ran into the same problem a few days ago and found a solution. Although it's more of a sloppy one it works!
Close your xDXDesigner and go to "...\MentorGraphics\PADSVX.1.2\SDD_HOME\common\win32\lib" and open the "dxdbdll.dll" with an editor. (better make a backup)
Find line 6794, column 150 and replace "MEG" with "M NUL NUL" and optional "K" with "k". In line 6794 column 234 replace "Mega (MEG)" with "Mega (M) NUL NUL" and "Kilo (K)" with "Kilo (k)".
You need to type those NUL down by yourself, by hitting ALT and typing 256 on the numpad. Don't leave any spaces! I just used them here to make it more readable.
FIND:
line 6794, column 150:
line 6794, column 234:
CHANGE TO:
line 6794, column 150:
line 6794, column 234:
I hope this helps! You obviously need to do this on every workstation you're using.
Greetings,
Fabian
