Simulation encounters error

[HxJi]

Summary

I tried to run the vector_add example under DirectProgramming/C++SYCL. The emulation runs well and the simulation can be compiled successfully. However, the simulation failed to run.

Version

oneAPI Toolkit version: 2023.01
oneAPI Sample version: 5be94f

Environment

OS: Ubuntu 22.04
Quartus Prime Pro 22.4
Questa Starter 22.4

Steps to reproduce

cd oneAPI-samples/DirectProgramming/C++SYCL/DenseLinearAlgebra/vector-add/
mkdir build
cd build
cmake ..
make fpga_sim
CL_CONTEXT_MPSIM_DEVICE_INTELFPGA=1 ./vector-add-buffers.fpga_sim

Observed behavior

The simulation failed and returned the following message:

The simulation process encountered an error and has aborted.
Error: The simulator's process ended unexpectedly. Check oneAPI-samples/DirectProgramming/C++SYCL_FPGA/Tutorials/GettingStarted/fpga_compile/part4_dpcpp_lambda_buffers/src/vector_add_sim.fpga_sim.prj/transcript.log for details.
vector_add_sim.fpga_sim: src/hls_cosim_ipc_socket.cpp:249: void IPCSocketMaster::connect(): Assertion `0 && "IPCSocketMaster::connect() call to accept() failed"' failed.
Aborted (core dumped)

Expected behavior

The simulation runs well.

@yuguen-intel Any ideas?

First time I'm seeing this issue, I'm sending the link to this issue to FPGA sim experts

What is the content of the transcript.log file?

Thanks for getting back to me. I am updating Quartus to a newer version 23.2 and rerun the simulation. Will upload the log file when it is done.
