Quartus does not support unresolved numbers from numeric_std!!!

I have just found that code using unresolved_unsigned is rejected by Quartus II (it is accepted by Modelsim). I tried including numeric_std_vhdl2008.vhd in my project, which resulted in syntax ...

What is this numeric_std_vhdl2008.vhd file you're talking about - its not a standard file.

Are you sure you werent confusing quartus, because you're using 2008 code with a '93 compiler?

And why are you doing multiple accesses to an array anyway? that will not result in a ram being infered?

From this and your other post, I have my suspicions you're not writing synthesisable VHDL and you're writing more like a software programmer. Can we have some example code that isnt working for you?
