Video-over-IP on new Quartus

I am trying to implement a Video over IP design on Cyclone III. Did anyone manage to compile and successfully use the whole package on any FPGA? Would be great if someone responds who had success or failed. I am mostly interested in successful designs on Cyclone III, but others are OK too. This thread is rather a problem log for starters, so maybe it will be useful for further users.

System: Quartus 10.1sp1

Devboards (didn't choose the right one yet):

Cyclone III Video Development Kit EP3C120

Cyclone III Starter Kit EP3C25 (should fit, since the ref design is on EP2C25)

Cyclone III Nios board (Also known as NEEK) EP3C25

Reference design: VoIP-2.4.0 by AN374

(2011-03-25)

Firstly I am trying to implement the reference design with no changes.

a) The SOPC builder doesn't find the required IPs.

Solution:

1. Create additional IP directory somewhere. E.g. C:\Altera\ip_cores.

2. Copy all the additional cores to that directory.

3. Open SOPC builder.

4. Go to Tools->Options...->IP Search Path.

5. Add a directory mentioned before.

6. The ethernet core drops an error, so choose the correct clock and connect to the bus. Fallow the advices on the SOPC message window.

b) The design fails dropping an error bacause of too small amount of M4K blocks.

Solution:

Switch fitter optimization to area (didn't check balance) instead of speed.

c) The design fails dropping an error after successful synthesis, fitting and assembling: "Output clocks to SDRAM Not Found "

Solution:

1) comment a line in %quartus_rootdir%\10_1\ip\altera\ddr_ddr2_sdram\lib\tcl\paths.tcl

# ::ddr::extract::follow_edge2 mux async "~DELAY_CELL\$" found_tco "" failflag

under extract_clk_tco procedure. Its in the end of the file.

OR (a solution, which I did not test)

2) Remove the DDR constraint from the .qsf file.

So far, the design compilation runs fine. However, I can't test it on the real hardware.

Will be updated.
