The exam schedule is found here:
/studier/emner/matnat/ifi/IN5220/v21/beskjeder/zoom_examination_in5220_v2021.pdf
Please note that we will start early (08.15) in order to complete all on the same day.
We will send out detailed schedule in short time
Since some students have exam close to the original deadline and we will have a late exam 11/6, we can extend the deadline to 4/6, at 23.59. The report shall be submitted using Devilry.
All groups have to demonstrate that the project design is working in Cadence. Please register on the Doodle poll:
https://doodle.com/poll/ha66kravcmfh75vc?utm_source=poll&utm_medium=link
Each group should spend around 10 minutes and show the following:
1. Show schematic of the SAR ADC
2. Show layout of the SAR ADC
3. Show a working simulation of the SAR ADC, preferably based on layout.
If you are not 100% finished or your system is not working properly, just show what you have. You will still have time after Thursday to fix before submitting the report.
Due to bank holidays this week, the demo session is moved to Thursday 20/5 in the lab class. We will set up a Doodle where the groups can register. All groups need to attend.
The lecture on Tuesday May 11th will be an individual project Q&A. Doodle poll signup will be posted later today on the course schedule.
As can be seen from the current status off the poll, it seems hard to find a date that is good for all. Can you check once more and only leave out dates which are absolutely impossible. If we cannot find a date that fits all, we will just ask the administration to set a date based on avoiding conflicts with other exams.

We have a common guest lecture with IN5260
Presentation title: «Ultra-low power wireless microcontroller design»
Lecturer: Frode M. Pedersen, Chief Architect, Nordic Semiconductor
To set the final ate for the oral exam in IN5220, please fill in this Doodle poll:

The two final project deadlines are both extended by two weeks. New deadlines are:
Demo of final system: May 12th in the Lab class
Submission of final report: May 26th
During update to the 65nm process, the SAR symbol had not been properly created, we have therefore made a new version of the SAR logic package that you can just replace in your design folder. Just follow the description originally provided with the SAR logic and it should work. If you have any problems, do not hesitate to ask.
There is a small typo in the DAC specifications; the resolution should be 8 bit and not 9 bit as written.
Also if you compare the I/O of the provided SAR logic it does not fully match the block diagram used in the project assignment. The SAR logic has the following signals:
Input signals:
clk: This is the clock for the SAR logic
soc: This is the Start-of-Conversion signal. It will reset the SAR logic to the starting state. Compared to the figure in the project assignment which has both reset and soc, this is combined in the SAR logic
keep: This signal monitors the output of the comparator and if it is inverted, the digital code is too high and one must revert back to the past state and move to a less significant bit.
Output signals:
dout: The eight bit digital output
done: Status signal telling the the bit cycling is completed and the conversion is done.
...After questions from student we have decided to extend the deadline of the second project milestone until 24/3. If you have already submitted and want to make some updates, you can re-submit in Devilry.
For the project milestone with deadline on 17/3, you only need to set up the test bench for the SAR ADC as a system. It means that the test bench must be designed such that you are able to simulate and document that your design meets the specifications for the ADC.
The ideal logic including Cadence symbol is found here:
/studier/emner/matnat/ifi/IN5220/v21/beskjeder/sar.zip
Just unzip the sar.zip file in the library folder. You can find it where you start Cadence and just type cd <folder>, where <folder> is the name of your library. Thereafter just unzip the file and it should appear in your library manager.
The fist short report should be submitted through Devilry within 3/3 at 23.59. Se below for the task:
03.03.2021 - A short description of one to two pages on how you understand this assignment and how you plan to solve it. Also, include the test input and predicted waveforms at different points and the output of the ADC.
From tomorrow 11.02 we will start with individual Cadence lab sessions. If you look any the schedule you will find a Doodle Poll, where the idea is that each group can select one time-slot of 15 minutes for individual Q/A. Please register and joint the meeting for your time-slot.
Below is the current group setup. One group currently has three students. As we have not received confirmation from all group members if they are still following the course, there may be changes the first few days.
Group 1: Andreas Haavik and Magne Gjennestad
Group 2: Emil Hultin, Jens Bulukin and Magnus Grøndalen
Group 3: Ole Georg Berg and Jurgen Asko
Group 4: William Pasnin and Tonny Nguyen Do
Group 5: Abdulkadir Ali and Jenny Sheng
Group 6: Amna Gulzar and Stian Skulstad
It seems that one of the servers under rh7login has problems. Its name is loft.ifi.uio.no, so if you end up at his server, please try to ssh to eldur.ifi.uio.no instead. The IT support team is on the case, but until it is fixed avoid loft.ifi.uio.no.
The course project description is found here:

The course design project will be presented in the lab-session tomorrow (Feb. 4th).
We are currently updating the 90nm tutorial for the 65nm process used in the course. Still the 90nm tutorial can be used for most functions, but for Monte-Carlo and Corner simulations you have to make some changes. Follow the instruction here:
/studier/emner/matnat/ifi/IN5220/v21/beskjeder/tutorial-correction-for-65nm-process.pdf
We have registered a Padlet for IN5220 where you can post questions etc. This is the first time we use Padlet, so we will probably have to optimize during the semester, but you should be able to access the Padlet here:
