COMPSYS 705 : Formal Methods for Safety Critical Software
Engineering
2024 Semester Two (1245) (15 POINTS)
Course Prescription
Course Overview
This is an interdisciplinary course inspired by software engineering and formal methods. However, this course has been adapted for applicability for computer systems engineering, mechatronics, bio- engineering and medical devices domains. Executable biology refers to executable computational models that mimic biological processes. In this course we will present a range of executable models inspired by formal methods especially for medical device validation. The range of formal methods considered here include a synchronous Statechart called SCChart for pacemaker modelling, a tool called Uppaal for pacemaker verification and a tool called Piha for the design of the cardiac conduction system, which will be validated using the SPIN model checker.
The course is taught in two parts:
Part 1-Fundamentals of model-based design founded on formal methods.
• Automatic verification of closed and open systems using model checking and module checking.
• Modelling and verification of a pacemaker using UPPAAL.
• Run-time verification and enforcement of medical devices.
• Formal modelling and verification using process algebras and bisimulation.
• Introduction to Cyber-Physical Systems (CPS).
Part 2-Industrial successes of formal methods
• Linear Temporal Logic and its industrial applications
• Satisfiability Modulo Theory
• Proof carrying code
• Correctness of software programs

Workload Expectations
This course is a standard 15 point course and students are expected to spend 10 hours per week involved in each 15 point course that they are enrolled in.
For each week in this course, you can expect 3 hours of lectures, up to 1 hour tutorial and labs, while the remaining time is spent on reading, thinking, developing solutions for the assignments and preparations for the test.
Delivery Mode
Campus Experience
Attendance is expected at scheduled activities including labs/tutorials to complete/receive credit for components of the course. Lectures will be available as recordings. Other learning activities including tutorials/labs will be available as recordings. The course will not include live online events including group discussions/tutorials. Attendance on campus is required for the test. The activities for the course are scheduled as a standard weekly timetable/block delivery.
Learning Resources
Course materials are made available in a learning and collaboration tool called Canvas which also includes reading lists and lecture recordings (where available).
Please remember that the recording of any class on a personal device requires the permission of the instructor.
Health & Safety
Students must ensure they are familiar with their Health and Safety responsibilities, as described in the university's Health and Safety policy
Student Feedback
At the end of every semester students will be invited to give feedback on the course and teaching through a tool called SET or Qualtrics. The lecturers and course co-ordinators will consider all feedback and respond with summaries and actions.
Your feedback helps teachers to improve the course and its delivery for future students.
Class Representatives in each class can take feedback to the department and faculty staff-student consultative committees.
Course workload percentages have been updated taking on student feedback from previous years.
Academic Integrity
The University of Auckland will not tolerate cheating, or assisting others to cheat, and views cheating in coursework as a serious academic offence. The work that a student submits for grading must be the student's own work, reflecting their learning. Where work from other sources is used, it must be properly acknowledged and referenced. This requirement also applies to sources on the internet. A student's assessed work may be reviewed for potential plagiarism or other forms of academic misconduct, using computerised detection mechanisms.
Class Representatives
Class representatives are students tasked with representing student issues to departments, faculties, and the wider university. If you have a complaint about this course, please contact your class rep who will know how to raise it in the right channels. See your departmental noticeboard for contact details for your class reps.
Inclusive Learning
All students are asked to discuss any impairment related requirements privately, face to face and/or in written form with the course coordinator, lecturer or tutor.
Student Disability Services also provides support for students with a wide range of impairments, both visible and invisible, to succeed and excel at the University. For more information and contact details, please visit the Student Disability Services’ website http://disability.auckland.ac.nz
Special Circumstances
If your ability to complete assessed coursework is affected by illness or other personal circumstances outside of your control, contact a member of teaching staff as soon as possible before the assessment is due.
If your personal circumstances significantly affect your performance, or preparation, for an exam or eligible written test, refer to the University’s aegrotat or compassionate consideration page https://www.auckland.ac.nz/en/students/academic-information/exams-and-final-results/during-exams/aegrotat-and-compassionate-consideration.html.
This should be done as soon as possible and no later than seven days after the affected test or exam date.
Learning Continuity
In the event of an unexpected disruption, we undertake to maintain the continuity and standard of teaching and learning in all your courses throughout the year. If there are unexpected disruptions the University has contingency plans to ensure that access to your course continues and course assessment continues to meet the principles of the University’s assessment policy. Some adjustments may need to be made in emergencies. You will be kept fully informed by your course co-ordinator/director, and if disruption occurs you should refer to the university website for information about how to proceed.
Student Charter and Responsibilities
The Student Charter assumes and acknowledges that students are active participants in the learning process and that they have responsibilities to the institution and the international community of scholars. The University expects that students will act at all times in a way that demonstrates respect for the rights of other students and staff so that the learning environment is both safe and productive.
