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 the 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; and design experiences. Submissions on modeling, analysis, and synthesis for emerging technologies and platforms are particularly encouraged.
The workshop format includes paper presentations, invited talks, social lunch and dinner gatherings, and recreational activities.

| Important Dates |
| Paper abstract submission: | March 20, 2026 (AoE) | |
| Full paper submission: | March 27, 2026 (AoE) | |
| Notification of acceptance: | May 3, 2026 (AoE) | |
| Final version due: | May 20, 2026 (AoE) |
| Submission Instructions |
Only complete papers with original and previously unpublished material are permitted. Submissions must be no longer than 8 pages (references excluded), double column, 10-point font (we recommend using the ACM template or the IEEE template, but not necessarily). Accepted papers are distributed only to IWLS participants.
Double-blind policy: IWLS uses a double-blind reviewing system. Manuscripts must not identify authors or their affiliations; those that do will not be considered.
If you have questions about how to meet these guidelines, please contact the program chairs before the submission deadline.

| IWLS Programming Contest |
The IWLS Programming Contest this year continues the logic-synthesis competitions held at IWLS in recent years. In contrast to previous years, the objective of this contest is not to find a single “best” solution per benchmark. Instead, the goal is to explore the tradeoff between area and delay.
For details, please check out the call for submission for the programming contest below.
IWLS 2026 Programming Contest Call for Submissions
Benchmarks. 100 new practical benchmarks, with file names ex200.truth through ex299.truth, were generated for this contest (with possibly a few duplicates from the previous years). The high-level descriptions are not disclosed because this is a logic synthesis competition and the participants are encouraged to develop optimization methods that are universally applicable, rather than tailored to specific known circuits.
