Does anyone here has you UP3 wrok well?

Which version did you download?

I have downloaded the "Accessing Memory" design for quartus 4.1 and if I don't modify it but directly download it to the fpga, it will work well. But if I modify a little, everything will changed:( PS: I am using Quartus 4.2.

Then I downloaded the "Accessing Memory" design for quartus 5.0 , and it still doesn't work anyway.

Do you just use the reference design or construct the system by yourself using the sls component( lcd & sram)? And what your quartus version is?

Thank you so much!!
