    Thread Summary
    
                The user encountered slow simulation times when simulating the ADP5074. The issue was resolved by moving the .ASC file from a network location to a local folder, which significantly accelerated the simulation time.

    Hi,
    

    I want to simulate ADP5074.
    

     
    

    But the simulation is about
    

     
    

    I changed the solver to alternate, but the simulation time doesn't changed.
    

    What is the problem? How can I accelerate the simulation time.
    

    Thank you for your help
    

    BR
