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

@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"
