This directory includes the shell versions, scripts, timing constraints and compile settings required during the AFI generation process. Developers should not modify or remove these files.
The [scripts] (./scripts) contains a script used to notify a developer that their build job is complete as well as a script used to copy the specific AWS Shell design checkpoint (DCP) to the appropriate directory during the HDK setup process (hdk_setup.sh).
The shell_stable soft link points to the shell version contained in this directory that is the current, qualified shell version that can be used by developers. Other shell versions may be available for reference but they are likely older, or exploratory.
Each shell release contains files specific to that release. These files are stored in a shell directory with the version included in the directory name. For example, the shell_v04261818 directory contains files specific to Shell Version 0x04261818.
The software directory contains common software files used in the HDK.
The verif directory includes reference verification modules to be used as Bus Functional Models (BFM) as the external interface to simulate the Custom Logic (CL). The verification related files common to all the CL examples are located in this directory. It has models, include, scripts, tb directories.
The verif models directory includes simple models of the DRAM interface around the FPGA, shell, and card. You can also find Xilinx protocol checkers in this directory.
The verif scripts directory includes scripts needed to generate DDR models and other scripts needed for HDK setup.
The verif include directory includes sh_dpi_tasks.vh needed for DPI-C.
The verif tb directory includes top level test bench related files common for all the CL examples.
