Unable to simulate hello world HLx in vivado

[t2shashwat]

Hello,

I am trying to simulate hello world program in vivado, located at _https://github.com/aws/aws-fpga/tree/master/hdk/cl/examples/cl_hello_world_hlx_ on EC2 instance (with centOS 7.9) using the FPGA Development AMI having Vivado 2021.2 version. The simulation of this program fails at the elaborate step. It throws the below error and exits the simulation.

ERROR: [USF-XSim-62] 'elaborate' step failed with error(s) while executing '/home/shrivast/aws-fpga/hdk/cl/examples/cl_hello_world_hlx/example_projects/cl_hello_world.sim/sim_1/behav/xsim/elaborate.sh' script. Please check that the file has the correct 'read/write/execute' permissions and the Tcl console output for any other possible errors or warnings.

ERROR: [Vivado 12-4473] Detected error while running simulation. Please correct the issue and retry this operation.

ERROR: [Common 17-39] 'launch_simulation' failed due to earlier errors.

When I dig into the tcl console output, I find that a dpi.so file is not created inside project's xsim directory, which is also highlighted in the tcl console with the following message:

Invalid path for DPI library: /home/shrivast/aws fpga/hdk/cl/examples/cl_hello_world_hlx/example_projects/cl_hello_world.sim/sim_1/behav/xsim/dpi.so

When I look further into tcl console, I find that dpi_xsim.tcl file was not executed. And it prints the following error in the console:

ERROR: [XSIM 43-3985] Problem with usage of options: unrecognised option '--additional_option'. Please see the usage below.

ERROR: Script failed:"/home/shrivast/aws-fpga/hdk/common/shell_v04261818/hlx/verif/scripts/dpi_xsim.tcl

Steps to reproduce: Follow below subheadings in this link -

• Setup HLx Environment

• Create Example Design (GUI)

• Simulation (Code should throw errors here!)

Any help is appreciated.

Thanks, Shashwat
