Raw binary file format

Hi Dimitrios.

I have since given up on VTR and Altera products altogether for my thesis. I have now switched to Xilinx.

As to your question, have you come across the net2vqm tool? It doesn't convert the VTR output to sof right away, but it re-introduces Quartus back into the CAD flow.

Hello

Thank you for your quick response. Did you reached to compile a project with vpr and then go back to Quartus to generate the bitstream.

I have spent lot of time searching about the structure of the sof file and now I am trying to synthesise with Odin II, optimise with ABC and place & route with VPR. The above tools are embedded in a CAD flow called VTR.

Best Regards

Dimitrios Agiakatsikas

I never attempted to run the entire CAD flow from HDL design to bitstream.

When I experimented with the tool, I concluded that it did not serve my purpose and so I stopped using it.

VPR generates 3 files:

.place for placement

.route for routing

.net for the final netlist after the P&R algorithm runs.

There's a tool created by the EECG group at the University of Toronto which converts .net files to .vqm

This tool is the nettovqm tool. (net-to-vqm)

Thanks, Socrates. Since SPI is usually msb first (http://en.wikipedia.org/wiki/serial_peripheral_interface_bus#data_transmission), does that mean the RBF file contents should go out LSB first?

RBF is just a simple binary format, that You can upload using simple serialization mechanism (e.g. SPI: SCK->DCLK, MOSI->DATA0). Except You need to do a byte-reverse before sending.
