Rapid recompile

No its not smart recomple or partitioning it's the new feature on Quartus 9.1.

I set it using...

set_global_assignment -name RAPID_RECOMPILE_MODE 
COMPATIBLE_PLACEMENT

I've found it to be of little use, unless I'm doing something wrong.

Hi Witty,

I was not aware of this new feature, but I can imagine how it works. The feature could only work in case that Quartus found a lot of nodes which does not change. I'm pretty sure that changing the input value of the reset will cause a lot of changes in your FPGA implementation. I would try a change which influenced only a small portion of your design (e.g reduce the number of bits of a counter)

Kind regards
