Pre-lab
The
pre-lab consisted of emailing Dr.Baker to obtain a CMOSedu account in
order to upload laboratory reports and reviewing Dr. Baker's webpage
that covers the basics of html and editing webpages on his CMOSedu
website.
Lab
description
This
laboratory introduces us to Cadence 6.1 for chip design, layout, and
simulation. For this laboratory, we are going through the first
tutorial up to the 25th image in the tutorial which consists of
installing Cadence and adding several files to the library so that
Cadence can run properly without any problems. At the end of each lab,
students are required to back up their files by creating a compressed
zipped folder and send it to google drive.
First thing to be done is to log-in into MobaXterm via secure shell (ssh) to the UNLV Cadence server and change directory to CMOSedu using the cd command and then starting cadence with the Virtuoso & command as seen in the image below
After
launching Virtuoso, two windows should appear which are the Command
Interpreter and the Library Manaager, the next step is to create a
library called Tutorial_1 and attach the AMI 0.60u C5N process as shown
in the image below.
Next,
I created a new file in the Tutorial_1 library and named it R_div, and
created a new a schematic of the resistive voltage divider with 10k ohm
resistors and a 1V DC source as shown below
I
then checked and saved the schematic to make sure that there were no
errors. After confirming that everything was in order, I proceeded to
simulate with spectre (Cadence's SPICE simulator) as shown in the three images below
Schematic Check
Spectre Simulation
Transient Simulation
After saving the state, I then ran the simulation and got the in voltage (green) at 1V which is the source voltage and got the out voltage (red) at 0.5 V shown in the image below
The
second part of this laboratory is to make sure that we back up our
files regularly while working on them by zipping up our work and
emailing it to ourselves or uploading it to google drive , dropbox,
etc. For my back up files, I zipped up my files and decided to make a
google drive for the class and send it to myself to ensure that if the
program crashes or my files are lost. Backing up files is really
important because it prevents you from losing your files in the future.
