With debug support enabled you can use xtensa-esp32-elf-gdb to debug the code used in the simulator.

Use xtensa-esp32-elf-gdb with the .elf file as the parameter:

 xtensa-esp32-elf-gdb compiled_file.elf
 

and the command below to connect (1234 is the default port):

 target remote localhost:1234

upload_port = com7
;upload_port = /dev/tnt2
build_type = debug
debug_tool = custom
debug_port = localhost:1234
debug_build_flags = -O2 -g
debug_init_break = tbreak main

      monitor system_reset
  end
  define pio_reset_run_target
      monitor system_reset

  target extended-remote $DEBUG_PORT
