I cant recall what exactly I did but, well some test code works
in the FPGA, pretty much all works in simulator, but in the real
FPGA design code does execute correctly, I used Chipscope connected
to the AVR core and looked at instruction trace, depending what
instruction follow some code is not executed incorrectly.
I looked at the VHDL and found that the RTL code can not be correct.
dont recall details, but I wasnt able to make a quick fix :(
did you run your code in the FPGA or simulator?
