Missing NV_NVDLA.verilog and Collecting generated RTL files about esp

[jzuckerman]

1. You can run the command make genus-setup from your SoC design folder. This will create two scripts inside a folder called genus: srcs.tcl and incdir.tcl. These contain all of the RTL sources and include directories, respectively.

2. Did you run make NV_NVDLA before running the simulation?

Thanks for your swift reply Jzuckerman!

You can run the command make genus-setup from your SoC design folder. This will create two scripts inside a folder called genus: srcs.tcl and incdir.tcl. These contain all of the RTL sources and include directories, respectively.

At which step during ESP flow, should I ran the make genus-setup to get the complete RTL filelist?

Did you run make NV_NVDLA before running the simulation?

I wish to try a single-core SoC design with the NVDLA accelerator and below is my expected ESP flow:

1. cd esp/socs/xxx/
2. make esp-xconfig and this step will produces the configuration file.
   

• Is the "caches" option mandatory when using NVDLA? If I choose to use "ESP RTL" implementation for the caches, are all of the caches files produced in .sv format?

3. make NV_NVDLA:

• Is this make target needed to run evertime?

5. make sim and run -all:

• Can these two simulation steps be skipped since I only have VCS simulator at hand?

6. make vivado-syn
7. make soft and make linux :

• The first command will produce prom.bin and systest.bin while the latter one produce the Linux image linux.bin. Can I put them into one SD card and boot the system automatically when clock and reset is on? Besides, it is said that the SoC runs at 50MHz but my FPGA board can only run 10MHz in maximum. Will the reduction of clock frequency cause problems?

In the third-party accelrator tutorial, authors mentioned that we need the list(.verilog and .sverilog) of hw files. However, they didn't provide .verilog and .sverilog, which make the compiler fail to find the relevant hardware sources files for NVDLA.

@jzuckerman Could you please provide an example file(NV_NVDLA.verilog) for us? Or tell us how to list all hardware source files in correct grammar in .verilog.

The NV_NVDLA.sverilog is empty because there is no System Verilog in the design. The NV_NVDLA.verilog is copied from one of these two files (https://github.com/sld-columbia/esp/tree/dev/accelerators/third-party/NV_NVDLA/config) when you run make NV_NVDLA, depending on whether you are targeting an FPGA or an ASIC.
