I want to know the max speed of NIOS ii based on cyclone iii EP3C120N780C

Hello vlsidc:

If you are using the MegaCore Function in your design,like DDR2 High Performance Controller or Triple Speed Ethernet,you should have all the necessary IP licenses.

The critical warning regarding the timing requirement not met maybe cause by the IP license.

In my design the open core plus logic has this name: "pzdyqx:nabboc|pzdyqx_impl:pzdyqx_impl_inst|FNUJ69 67" and is generated only when you do not have a valid license for the ip in your system.

I'm disturbing by this trouble for a long time till I spend heap dollars on the licenses.

Then the nios/f is working fine under 133mhz with the full speed DDR2,tse and others.
