Hi After compiling the project with Quartus II. These timing constraint 
errors have been displayed:


Slack  From  To  Recommendations
1  -0.441  SENSOR_TOP:\GEN_P...han3~62_OTERM597 
SENSOR_TOP:\GEN_P...han3~62_OTERM597  Report recommendations for this 
path
2  -0.364  SENSOR_TOP:\GEN_P...han3~62_OTERM597 
SENSOR_TOP:\GEN_P...han3~62_OTERM597  Report recommendations for this 
path
3  -0.359  SENSOR_TOP:\GEN_P...han3~62_OTERM597 
SENSOR_TOP:\GEN_P...han3~62_OTERM597  Report recommendations for this 
path
4  -0.339  SENSOR_TOP:\GEN_P...han3~62_OTERM597 
SENSOR_TOP:\GEN_P...han3~62_OTERM597  Report recommendations for this 
path
5  -0.262  SENSOR_TOP:\GEN_P...han3~62_OTERM597 
SENSOR_TOP:\GEN_P...han3~62_OTERM597  Report recommendations for this 
path

Then when I click into "Report recommendations for this path" to analyze 
this error with time quest analyzer, the time quest analyzer gives me 
another error and it is closed automatically. Is this a bug of the 
program?? Find attached the screenshot of the exception.

Thanks
