In this lab were going to practice publishing our web pages to the website. Also, were going to get Electric set up on our computer.    

To begin, download electric and open it. You should see the following screen.

 

   
It is strongly preferred to use a white background as opposed to a gray or dark background. Select Window -> Color Scheme -> White Background Color. This will be easier to read.
     

     

We will be using the C5 process in this class and fabrication through MOSIS. We will have to configure Electric to be compatable with this process.

     

Select the preferences menu (File -> Preferences) and configure Electric as shown below.

   

   

The scale for the C5 process is 300 nm, this needs to be setup in Electric. Select File -> Preferences -> Technology -> Scale and configure Electric as shown below.

   

     
Press ok to save and exit. It may prompt you to ask if you want to mark all libraries with these settings. Select "mark all libraries."
You may want to configure Electric's key bindings at this point.
   
Next lets create a new library and then a schematic. Select Go To File -> Save Library As and name the library whatever you prefer.After that, create a new cell. Select Go To Cell -> New Cell and select schematic.

     

     

Next select the component tab and this is what you should see.

   

     

Next were going to place an n-well resistor. Note the resistor icon on the left (it is set to place a "normal" resistor). Click on the arrow portion and select n-well resistor. Place an n-well resistor on the schematic. If you set your key bindings above, you can press f to zoom-to-fit.

   


         

Lets change the properties of this resistor. The sheet resistance of the C5 process is about 800 ohms. Thus, lets use a width of 15 and a length of 187.5 to make a 10 kohm resistance.

     

 

     

Lets have a look at the modified resistor properties on the schematic.

     

     

Wow! What an incredible resistor!

    

I strongly prefer to prepare my website files on my own computer before I upload it to CMOSedu. So I will prepare the folder on my local computer and then upload a copy upon completion. The folder stored on my computer will serve as my backup. The folder is shown on our desktop.

     


     
Here is a look inside the folder where all my hard work is saved!
