Csim failed with below error. Add '#include <cstdlib>' in file beamformer_tb.cpp can fix the issue.

INFO: [SIM 211-2] *************** CSIM start *************** INFO: [SIM 211-4] CSIM will launch CLANG as the compiler.

@qingqins I've tried on both Vitis Unified IDE 2023.2 and 2024.1. without adding '#include ' in file beamformer_tb.cpp , C-Sim can complete successfully without any error.

Hi @allyzhou , Thanks for checking. The issue is fixed in latest code. I close this issue. Previous only include one file: #include "beamformer.h"

Latest: #include <stdio.h> #include <math.h> #include "beamformer.h"
