4.3. Reporting (dla_compiler Command Options)
When a graph is compiled, the following CSV files are created by default to provide additional information about the input and output tensors and how they map to FPGA AI Suite IP tensors:
You can disable the generation of these reports with the --fno-transform-tables command option.
input_transform_dump Report
The input_transform_dump file is a CSV file with input tensor dimension, striding, padding, and precision. The input_transform_dump report is provided in a file named input_transform_dump_<graph_name>.csv
An example of a simple output CSV file created from an AlexNet graph is as follows:
| depth |
height |
width |
height stride |
width stride |
top pad |
left pad |
Bot pad |
right pad |

Additional information about the initial scale and shift performed on the tensor is included separately.
input_transform_mapping Report
The input_transform_mapping file is a CSV file that shows the element-wise mapping of the logical input tensor elements to the FPGA AI Suite input tensor format. The input_transform_mapping report is provided in a file named input_transform_mapping_<graph_name>.csv.
The transform mapping report has columns corresponding to the offset and subscript indices for the logical input tensor elements, and the corresponding elements in the transformed FPGA AI Suite input tensor.
For more information about contents of the input transform mapping report, refer to "Input Transform Mapping" in the FPGA AI Suite IP Reference Manual .
output_transform_dump Report
The output_transform_dump file is a CSV file with output tensor offsets and dimension (batch, depth, height, width). Output transforms tables are named output_transform_dump_<Graph_name>.csv
An example of a simple output CSV file created from an AlexNet graph is as follows:
| batch dim |
depth dim |
height dim |
width dim |
batch offset |
depth offset |
height offset |

output_transform_mapping Report
The report is a CSV file that show the element-wise mapping of the FPGA AI Suite output tensor format to the logical output tensor. The output_transform_mapping report is provided in a file named output_transform_mapping_<graph_name>.csv.
This mapping in the output_transform_mapping report is the inverse of the input mapping described in the input_transform_mapping report.
For more information about the output tensor format, refer to "Output Tensor In-Memory Format" in the FPGA AI Suite IP Reference Manual .
