I am working on an esp project and compiled my code by using the esp32s2 toolchain and created a binary that ready to run on a real device. But I don't have a real device to test my binary. Is there any simulator to simulate the ESP32-S2 chip or the ESP32 chip?
Is there any simulator for ESP32-S2 or ESP32 chips?

You can use Wokwi to simulate the ESP32, and soon also the ESP32-S2.The Wokwi is a free online simulator for electronics, and it runs in your browser. This means you can simulate code that interacts with 3rd-party sensors, display modules, LEDs and many other common parts. There's also initial support for WiFi simulation, and the developers are working on extending it to support connecting to any host on the internet (e.g. HTTPS/MQTT)
Simulator Examples
Arduino Examples
APA102 Color Cycles (TinyPico Board)
MicroPython Examples
ESP-IDF Examples
The following examples use the ESP-IDF functions. They are compiled using Arduino ESP32 Core:
Binary LED counter using FreeRTOS tasks
GPIO button input + interrupts
https://docs.wokwi.com/guides/esp32
You can try QEMU from https://github.com/espressif/qemu or https://github.com/Ebiroll/qemu_esp32
Not sure if they are supporting ESP32-S2, but it seems to be working with ESP32.
