Synthesis and Optimization of Microelectronic Systems II

08:15 - 09:45
15:30 - 17:00

Start: Thursday, May 23, 2024

Exam information:

The written exam will take place on Thursday, 25th of July, at 15:30 in 11-262.

The course is dedicated to Master's students of electrical and computer engineering with specialization in Embeddeded Systems or Integrated Systems. 3 ECTS credit points can be earned.


This lecture is part of the Erasmus Mundus Distinguished Lecture Series on Embedded Systems and will be given by Prof. Maciej Ciesielski, University of Massachusetts at Amherst, USA.


No previous knowledge is required from "Synthesis and Optimization of Microelectronic Systems I". Part I deals with the higher design levels while part II of the lecture focuses on lower design levels. Both parts can be attended independently from each other.

More information and documentation can be found on the UMass Logic Synthesis course website.

Maciej Ciesielski received the M.S. in Electrical Engineering from Warsaw Technical University in 1974, and Ph.D. in Electrical Engineering from the University of Rochester in 1983. From 1983 to 1986 he was a Senior Member of Technical Staff at GTE Laboratories, Waltham, MA, where he worked on silicon compilation and layout synthesis projects. In 1987 he joined the Department of Electrical and Computer Engineering at the University of Massachusetts, Amherst, where he is currently Professor and Associate Department Head. He teaches and conducts research in the area of electronic design automation, and specifically in high-level and logic synthesis, formal verification and design validation of digital systems. He is recipient of Doctorate Honoris Causa from the Université de Bretagne Sud, Lorient, France, in 2008. He is a senior member of the IEEE.

Retiming is covered on pages 462-471 (book) or 471-480 (pdf file) but it basically covers the entire course (and more!).

You can also see the paper by Shenoy and Rudell, "Efficient Implementation of Retiming", 1994:

You only need to read first three pages (up to Section 3.2) to get a good idea about retiming.
