Hi Anand,
The below mentioned error usually occurs from any issue with the block name or path:
"Invalid Simulink object name: i_v_flux_of_memristor/Sine_wave".
You can try the following troubleshooting steps:
  • Ensure that the Simulink model ‘i_v_flux_of_memristor’ is loaded using the command ‘open_system('i_v_flux_of_memristor')’.
  • Verify that the block "Sine_wave" exists with the correct name and path. It can also be helpful to use the Simulink model browser to identify any discrepancies or hidden characters in the path.
I hope this helps!
