The steps for PCB simulation software to perform LAYOUT simulation are as follows:
1. Import layout files: Import the layout files generated by PCB design software into the simulation software. The layout file will include information such as the layout of the circuit board, component locations and connections.
2. Set simulation parameters: Set simulation parameters in the simulation software, such as simulation device, simulation type, simulation time, etc. These parameters will determine the scope and level of detail of the simulation.
3. Run simulation: The simulation software will perform simulation calculations based on the set parameters. The simulation process usually involves the analysis of various aspects such as voltage, current, power, and signal integrity of the circuit.
Please note that these steps may vary depending on the specific PCB simulation software. During actual operation, it is recommended to refer to the user manual or online help document of the specific software to obtain more detailed and accurate information.
