Hi all,I use Quartus II version 10.1cb for my design in Cyclone III LS with "security separations" features, It worked fine. I upgraded to Quartus II version 10.1sp, the fitting ran for 3 days without complete. When I converted all security regions to unsecurity regions, it finished in one hour. Can anyone tell me what wrong with this. Thanks.
