[PCB_FORUM] Re: Constraint Enabled ERROR

Because the EE opened Constraint Manager in ConceptHDL...
 
How you doing Paul ;-)

Subject: [PCB_FORUM] Constraint Enabled ERROR



#1   ERROR(300) Net Rev fatal error detected. 

Design flow is Constraint Manager enabled, require pstcmdb.dat and
pstcmbc.dat files. 

 This is from a board that was done a year ago using Allegro and Concept
HDL 15.5 Without ANY constraints added to either the board or the
schematic. We now have 15.7 loaded and want to do an ECO to the layout,
the Eng. makes the schematic change and when we run the loop from
Project Manager ( Export Physical ) it packages clean but we get the
error above while tying to update the board file. I don't want this
project CM enabled, I don't have anything to enable! I guess I'll have
to be CM enabled but how do I get the 2 files above that I need? 
 The question is this:   Why are we constraint enabled we don't even
have a lic. for ConceptHDL that can open CM? We are not doing anything
different ( maybe we should be ) from the way we've been doing ECO's for
years. Are we the only people having this trouble since we upgraded to
15.7, also we do have many boards that are using CM for much of the
placement and routing ( I really like it ) but every simple schematic
change like adding a resistor we have trouble with the CM enabled
problem 

   Thanks
