RTM Kernel Test¶
L2 RTM kernels have been tested against the implementation in python. That is, a python based testing environment has been developed to generate random test inputs for each RTM kernel, compute the golden reference, and finally compare the golden reference. To run the testing process of L2 kernels, please follow the steps below.
Set up Python environment¶
Please follow the instructions described in Python environment setup guide to install anaconda3 and setup xf_hpc environment. All testing should be run under xf_hpc environment. Please deactivate xf_hpc environment after testing.
Set up Vitis environment¶
Please navigate to directory L2/tests, and change the setting of environment variable TA_PATH to point to the installation path of your Vitis 2020.2,
and run following command to set up Vivado_hls environment.
export XILINX_VITIS=${TA_PATH}/Vitis/2020.2 export XILINX_VIVADO=${TA_PATH}/Vivado/2020.2 source ${XILINX_VITIS}/settings64.sh
Test RTM kernels¶
There are several pre-build L2 kernels and they can be tested individually. To launch the testing process, please navigate to each testcase directory under L2/tests/hw, and enter the following command for software emulation, hardware emulation or running on hardware.
make run TARGET=sw_emu/hw_emu/hw
Test 2D RTM¶
Forward kernel¶
make run TARGET=sw_emu/hw_emu
The above command will test and verify forward kernel via Vitis software-emulation or hardware-emulation. Once the emulations are pased, one can use the following command to build FPGA bitstream and launch the kernel on Alveo U280 FPGA.
make build TARGET=hw make run TARGET=hw
The paramters listed in the following table can be configured with make command. Notice that RTM_time must be multiple of RTM_numFSMs.
| Parameter | Default Value | Notes |
|---|---|---|
| RTM_maxDim | 1282 | Compile time: One dimmention limit |
| RTM_NXB | 40 | Compile time: Boundary width |
| RTM_NZB | 40 | Compile time: Boundary height |

Backward kernel¶
make run TARGET=sw_emu/hw_emu
The above command will test and verify backward kernel via Vitis software-emulation or hardware-emulation. Once the emulations are pased, one can use the following command to build FPGA bitstream and launch the kernel on Alveo U280 FPGA.
make run TARGET=hw
The paramters listed in the following table can be configured with make command. Notice that RTM_time must be multiple of RTM_numBSMs.
| Parameter | Default Value | Notes |

RTM kernel¶
RTM kernel is a combination of forward kernel and backward kenrel. It fulfils the entire RTM algorithm.
make run TARGET=sw_emu/hw_emu
The above command will test and verify RTM kernel via Vitis software-emulation or hardware-emulation. Once the emulations are pased, one can use the following command to build FPGA bitstream and launch the kernel on Alveo U280 FPGA.
make run TARGET=hw
The paramters listed in the following table can be configured with make command. Notice that RTM_time must be multiple of RTM_numFSMs and RTM_numBSMs.
| Parameter | Default Value | Notes |
|---|---|---|
| RTM_maxDim | 1282 | Compile time: One dimmention limit |
| RTM_NXB | 40 | Compile time: Boundary width |

| RTM_width | 10 | Running time: Image total widht |
| RTM_time | 12 | Running time: No.time |
Test 3D RTM¶
Forward kernel with HBC/RBC boundary condition¶
make run TARGET=sw_emu/hw_emu
The above command will test and verify forward kernel with HBC/RBC boundary condition via Vitis software-emulation or hardware-emulation. Once the emulations are pased, one can use the following command to build FPGA bitstream and launch the kernel on Alveo U280 FPGA.
make build TARGET=hw make run TARGET=hw
The paramters listed in the following table can be configured with make command. Notice that RTM_time must be multiple of RTM_numFSMs. RTM_z must be less than RTM_maxZZ and be multiple of RTM_nPEZ. RTM_x must be multiple of RTM_nPEX.
