what about this warning

when i insert scan chains, it rpts this:

Code: 
  Architecting Scan Chains
Warning: There exists a cell ADC on the bus which is not controllable. So the tristate disabling logic on this bus is not synthesized. (TEST-591)

Click to expand...

i think that these warnings are generated by the three-states which can not be disable, u should man the warning info for details and maybe u should add bus-keeper to solve these warnings.
 

what about this warning

Thanks for all the person that helped me.
U help me to solve the problem.

set_dont_touch [find_cell cell/*] solve the problem
