Circuits Intégrés Numériques et Analogiques (CIAN)

The team members have expertise in various areas of electrical engineering and computer science and are active on topics that fit very well into the core research orientations of LIP6, including smart devices, security and reliability. It aims to provide solutions to the challenges resulting from the miniaturization and heterogeneity of integrated circuit technologies and the need for high reliability and security. Miniaturization leads to the explosion of complexity in terms of components and to the rise of defect levels. The group also focuses on the coexistence of multi-domain and multi-physical environments (analog/RF, digital, MEMS, magnetic, organic. etc.).

Most of the projects carried out are application driven and all projects culminate with a demonstrator, namely a circuit prototype or a computer-aided design tool, that serves as a proof of concept. The team strongly encourages technology transfer by communicating the projects’ results to interested specializing companies, as well as through the creation of start-ups.

The team seeks establishing collaborative links with other teams in the laboratory, as well as with academic and industrial partners form France and abroad, by means of national and international projects. Team members contribute to the organization of conferences and serve as program committee members of conferences and editors in international journals. They also participate very actively in reviewing projects submitted to national and international funded research programs.

Key numbers


  • 11 permanent researchers (Associate, Emeritus, and Full Professors, as well as CNRS researchers),
  • 7 PhD students, 2 post-docs, and 2 research engineers.

For the past 5 years:

  • about 3.3 M€ collected grants, most funded by international grants (57%) or national agencies (32%) and 5% from industrial collaborations,
  • about 130 articles in conferences, 60 in journals, 4 books, 4 softwares and 7 patents.


  1. Proof of concept in Silicon: The team is capable of implementing solutions all the way form conceptual modeling, to design, to final physical implementation. By the end of most projects, we demonstrate circuit prototypes in advanced technology nodes. Examples include :
    • the design of high-performance RF communications for IoT [1],
    • the design of a RISC processor for integration into the ALSOC TSAR manycores project,
    • the development of an innovative solution for the synchronization of clocks based on a parallel PLL network [2], and
    • a FPGA architecture secured against DPA attacks [3].
  2. The team has launched several start-ups in the recent years (FlexRas focusing on FPGA partitioning, Intento Design focusing on automatic analog circuit synthesis and optimization, and Seamless Waves on cognitive radio design). FlexRas was recently acquired by Mentor Graphics, one of the top three firms on EDA.
  3. The team has released Free Open Source Software:
    • CORIOLIS for placement and routing of CMOS circuits
    • ALLIANCE for VLSI CAD flow, including a library of standard cells
    • OCEANE for sizing analog functions integrated in silicon
    • TAS for timing analysis
