<DIV>hi Davide,</DIV>
<DIV> </DIV>
<DIV>Translate Project Oberon from XC3 to XC6 is simple task for who have some
FPGA skills, the problem with this board and others is the memory type. The
original Oberon project are using a static RAM with a memory management
simpler.</DIV>
<DIV> </DIV>
<DIV>To implement the project Oberon with SDRAM you need add hardware for memory
management; this task have some side effects not simple to handle without
performance penalty.</DIV>
<DIV> </DIV>
<DIV>In practice, for my embedded controllers this additional complexity is not
justified.</DIV>
<DIV> </DIV>
<DIV>Regards,</DIV>
<DIV>Walter</DIV>
