Hello. 

 

I have a problem with CYCLONE III (EP3C25Q240C8NES). 

I have a unit in my design which Quartus II v7.1 SP1 can synthesis using LCELLs or can use memory blocks inside device. If I tell quartus to not use memory blocks my project works as expected, but if I tell quartus to use memory blocks in my project this unit doesn't work at all. If I use this project with CYCLONE II device the project works fine even if I use memory blocks. 

Why ?:confused:  

Is there a problem with CYCLONE III or with Quartus II v7.1 sp1 ?
