Dear forum,

I am Using Multisim and Ultiboard software for circuit simulation and PCB Development.

I am facing issue while creating custom component in multisim.

i will be attaching the all the screen shots for better understanding of my problems in multisim.

Opened new design FileCreating the custom component (Tool-custom component wizard)Filling up Custom component name and author filed.Selecting the Footprint type and Number of pin count.Creating a symbol for LM1117Assigning the pin direction. What is section column means there?Mapping of pins with footprintafter mapping of all the pinsModel name and Spice model file.Pin mapping tableAdding component to analog family

Circuit is created based on the typical application information

Simulation is running, Red line is input and Blue line is Output.No output at channel B.

Using this spice model

For customizing the design which spice model need to be used and how to do pin mapping for custom created symbol.

There is one video for to showcase this how to create custom model and importing spice model to that, but that video is not much help full to know the things. is there any better video to know how to import custom spice model to multisim. kindly help me to get solution for this problem.

First zip file is original zip file. Second zip file is edited one, in second zip file .cir file was not there so i copied the net list of LM1117 IC. made .Cir file myself.
