Double "set_location_assignment" in .QSF-file after a back-annotation

Hello, 

 

has anyone an idea why the QuartusII puts 2 almost identical 

"set_location_assignment" statements in the .QSF-file after a 

Back-annotation: 

 

 

------ snip ------- 

set_location_assignment PIN_A11 -to FL_D[7]~7 

set_location_assignment PIN_A11 -to FL_D[7] 

set_location_assignment PIN_B14 -to MX2_D[2]~2 

set_location_assignment PIN_B14 -to MX2_D[2] 

------ snip ------- 

 

QII/V7.0 also with QII/V6.x 

DEVICE EPM570F256C5 

 

QII doesn’t care about this, but if you use this file in the MENTOR I/O Designer  

(like we do ...) the I/O Designer fails and you have to edit the .QSF-file manually.  

That's really painful. 

Is this a feature or a bug or simply a user error? :(  

 

Kind regards Frank
