30th International Workshop
on Logic & Synthesis

July 19 – 21, 2021

Virtual Conference

Our sponsors


The International Workshop on Logic and Synthesis is the premier forum for research in synthesis, optimization, and verification of integrated circuits and systems. Research on logic synthesis for emerging technologies and for novel computing platforms, such as nanoscale systems and biological systems, is also strongly encouraged. The workshop encourages early dissemination of ideas and results. The workshop accepts complete papers highlighting important new problems in the early stages of development, without providing complete solutions. The emphasis is on novelty and intellectual rigor.

Topics of interest include, but are not limited to: hardware synthesis and optimization; software synthesis; hardware/software co-synthesis; power and timing analysis; testing, validation and verification; synthesis for reconfigurable architectures; hardware compilation for domain-specific languages; design experiences. Submissions on modeling, analysis, and synthesis for emerging technologies and platforms are particularly encouraged.

The workshop format includes paper presentations, posters, invited talks, social lunch and dinner gatherings, and recreational activities. Accepted papers are distributed exclusively to IWLS participants.
