Does the alt_u16 type support 0xFFFF or not?

[Altera_Forum]

Please consider the following code: 

  ... alt_u16 i; .... for(i=0x0000; i<=0xFFFF; i++) ...   I am getting the following warning during my compilation:  comparison is always true due to limited range of data type  To temporarily solve this I changed the upper limit from 0xFFFF to 0xFFFE  My questions are: 

1. Why this is happening? I ask this because I was thinking that the alt_u16 as an unsigned 16 bit could fit the 0xFFFF 
2. Do I need to increase the type alt_u16 to alt_u32 only to support one additional bit or how can I solve this problem?

alt_u16 can hold 0xFFFF, but it can't hold anything larger than that. So the comparison "<= 0xFFFF" is always true. Which is exactly what the compiler is telling you the problem with your code is. 

 You can use an alt_u32 to keep the rest of your for() loop the same as already written.
