EE 421L Digital Integrated Circuit Design Laboratory
Fall 2015, University of Nevada, Las Vegas

Student lab reports are found here.

Current grades are located here.

Project – your end of semester projects will be fabricated using the C5 process through MOSIS. These chips will be used next time EE 421L is taught to add an electrical measurement component to the lab.

Chip projects fabricated as a result of this lab are: top1, top2, top3, top4, top6, and top7

First half of the project (no layout, just schematics and symbols), of your design and an html report detailing operation (including simulations), is due at the beginning of lab on Nov. 9. 

Ensure that you have schematics with simulations for all of the cells listed below.

Your up/down counter, for example, should be simulated showing, counting up, down, or both, resetting then counting, etc.

Put your report (proj.htm) in a folder called /proj in your directory at CMOSedu.  

Dr. Baker will go over your designs with you, including running simulations, when lab meets on Nov. 9.

Second half of the project, a verified layout and documention (in html), is due at the beginning of lab on Nov. 23.

Again, I will meet with you on Nov. 23 to go over your layout and, again, put your report in the /proj folder in your directory at CMOSedu.  

Ensure that there is a link on your project report webpage to your zipped design directory.  

Finishing the projects by Nov. 23 will give us time to assemble chips for fabrication through MOSIS. 

• Design of an 8–bit resettable (input "clear") up/down counter 
• The outputs of your counter should be buffered before connecting to a pad
• A 31–stage ring oscillator with a buffer for driving a 20 pF off–chip load
• NAND and NOR gates using 6/0.6 NMOSs and PMOSs
• An inverter made with a 6/0.6 NMOS and a 12/0.6 PMOS
• Transistors, both PMOS and NMOS, measuring 6u/0.6u where all 4 terminals of each device are connected to bond pads (7 pads + common gnd pad) 
• Note that only one pad is need for the common gnd pad. This pad is used to ground the p–substrate and provide ground to each test circuit
• Using the 25k resistor laid out below and a 10k resistor implement a voltage divider (need only 1 more pad above the ones used for the 25k resistor) 
• A 25k resistor implemented using the n–well (connect between 2 pads but we also need a common gnd pad)

Policies

• Unlike the lectures, laptops can be used during the lab. Please bring your laptop with you to lab!

• If a quiz is open book then only the course textbook can be used (no ebooks, Kindle, Nook, etc., older/international editions, or photocopies).

• No late work accepted. Regularly being tardy for labs, leaving in the middle of labs, or leaving early is unacceptable without consent of the instructor.

• Cheating or plagiarism will result in an automatic F grade in the lab

• Email questions should be sent to the CMOSedu Google group (not directly to the instructor) at CMOSedu@googlegroups.com.

• Questions for the instructor (only) should be asked in person (not via email).
