recompile and integrate NVDLA RTL

[ramcn]

Hello,

I was looking for some instructions to recompile modified NVDLA RTL and integrate it into firesim.
Below is my high level understanding:

1. Compile the RTL and generate a new AFI on AWS FPGA AMI using below instructions
   http://nvdla.org/vp_fpga.html#generating-the-afi-on-aws-fpga-ami
2. Add the new AFI id in "config_hwdb.ini"
3. Edit defaulthwconfig in config_runtime.ini to specify the above new entry  config_hwdb.in.
4. Follow the firesim documentation to launch the simulation to use the new RTL.

It will be great if someone can validate this.

Thank you,
Ram

Thanks for the response farzad. I had a quick look at it. It seemed more like a document to configure the firesim FPGA image and not NVDLA as such. I was trying to figure out how NVDLA RTL compilation (using VCS) fits in this integration process. For example changing the number of MACs, recompiling the RTL on a system which has VCS license and integrating it into firesim soc on AWS.

So thought this is the right document to begin with:
http://nvdla.org/vp_fpga.html#generating-the-afi-on-aws-fpga-ami

Please let me know if my understanding is incorrect.

Thanks,
Ram

This link is not related to FireSim-NVLDA but rather to the NVDLA "Virtual Platform". Similar to FireSim-NVDLA, it runs on EC2 but it's totally a different beast.

You can follow this to make a new NVDLA verilog based on predefined configurations (e.g. nv_small and nv_large): http://nvdla.org/hw/v2/environment_setup_guide.html. Or you can edit the generated verilog by hand if you know what you are doing.
And follow this to run the unit tests that come with NVDLA: http://nvdla.org/hw/v2/verif_guide.html

After making sure that your customized verilog is healthy and can be synthesized by Vivado, you should replace the NVDLA verilog files in firesim-nvdla/target-design/firechip/nvidia-dla-blocks/vsrc/large with your customized ones and modify this Tcl script accordinagy: firesim-nvdla/platforms/f1/aws-fpga/hdk/cl/developer_designs/cl_firesim/build/scripts/encrypt.tcl. Then follow the instructions in Building Your Own Hardware to make a new AGFI.
