can results change if I synthesize again?

Jump to solution

hi.

 

I experienced a different operation when I re synthesised without changing programs and synthesis option.

 

Previously well-behaved programs did not work after re-synthesis.

 

I want to make a custom ip so that it does not have to be rewritten each time.

 

However, this problem reduces reliability.

 

In what situations can this be happening?

@tifmdgo01,

 

The results should not change if the source and project properties are not altered. 

You can compare the log file to know which stage in synthesis is changing. Also check the following AR
