Ancillaries Some Proprietary Software Packages: • • • • • PISCES (Stanford University) MINIMOS (Technical University of Vienna) DAMOCLES (IBM) ATLAS (Silvaco: www.silvaco.com ) MEDICI (Synopsys: www.synopsys.com) Academic Ethics All assignments should be student own work. Simply copping someone else’s homework is unethical. It will be considered as cheating. All kind of cheating will be punished. • Students are encouraged to discuss the problems together. • It is responsibility of each student to save his/her work. • Cheating in any work brings zero point • Signing in for someone else drops lecture visa Dr Ayhan Ozturk 4 I s t a n b u l T e c h n i c a l U n i v e r s i t y Dissection of Ethics Points(+5p) • • • Original HWs: Original Exams: Attendance: 30% 30% 40% Bibliography [1] Leblebici, D, Elektronik Elemanlari, IST: Sistem, 2002.
