Problems with FLEX10KE

Hi all, I have same firmware that burned on many boards. on 40% of the boards it runs without any problems. on other 60% it gives wrong results. I know for sure that the problem is in the FPGA...

Acording to Quartus this design can work with up to 16MHz, the crystal is 8MHz no PPL used.

Part of the design is communication with other boards, I cannot reduce clock freq so easyly.

To day there are boards that works perfect (40%), but also threre are many boards that doesn't work (60%).

The design mesures errors in step motor position and speed.
