Lab Description
- introduction to the editing and publishing process of html webpages for lab procedures
- introduction to the installation and use of Cadence Software
Pre-Laboratory Procedure
- acquire CMOSedu password from Dr. Baker
- review cmos.edu regarding editing of html webpages
Figure 1: creation of my CMOSedu student directory
Laboratory Objectives
1.) Complete Cadence Tutorial 1 up to image 25
- include some images of the tutorial with coherent narrative
2.) Discuss the procedure of performing regular backups on future lab reports
Laboratory Procedure
Task 1:
Upon
completing the installation procedures and installation of Cadence
software the program is ready to run. Below we can see the inital login
to UNLV ECE server using the provided student credentials. Upon
navigating to the CMOSedu directory we can use the 'virtuoso &' to
launch the program and begin.

After adding the Tutorial 1 library we are ready to create a new cell view.

Below
you can see the creation of a new cell view schematic called R_div to
allow us to build a voltage divider using two 10k resistors.

Once
our circuit is created, resistor and voltage source values are defined,
and our nodes are labeled properly we can now perform a check and save.

After the check and save confirmation we can run a simulation.

Above we see the simulation parameters that will be ran during this portion of the lab

Simulation results and netlist for the 1s transient simulation are shown above showing 500mV output
Task 2:
Regular backups will be performed using portable microSD, Lab folders located in my personal Google Drive, and at home NAS.

We can see the first backup of Lab 1 files ready to be transfered to backup location in the photo above.
I have created a backup file in my Goggle Drive to store and save Cadence backup files shown below.
