    -- Automatic testing of deisgn Kit extraction flow.
    I did develop a flow for testing layout extracted devices to guaranty
    the correct design kit extraction rules.

    -- Benchmarking of ADS simulation software.
    I develop several test bench for analyzing ADS simulator and its performances versus Spectre.

    -- Development of automatic test bench for simulation.
    Based on my needs of numerous number of simulation for Monte-Carlo analysis, I did develop a flow and software for creating simulation test (Monte-Carlo, sweep and corner) by using several Spectre process in parallel to reduce design characterization. The flow is based on LSF system.
    This flow was used in the process analysis of wireless product Zelda to find process dependencies of all specifications of the IC.
    The flow was integrated in a CAD product in NXP for all designer.

    -- Development of process block and software for mismatch analysis.
    This development was based on the lack of correct software able to help designers to find root cause of matching problems.
    This flow is based on Monte-Carlo and correlation analysis.
    A special Matlab program has been developed in Matlab to retrieve
    devices that contribute on mismatch deviation during simulation.
    The software analyses the correlation between mismatch parameters and measurement from Monte-Carlo results. This flow has been implemented in Spectre and Cadence after a collaboration with Cadence R&D.

    -- Deployment of Robust IC design on NXP

    Development of an architecture of PLL with fast locking phase in technology BicMOS6G.
    The basic idea of this architecture is simple. During locking phase, the PLL run in fractional mode
    and then the PLL pass into integer mode in normal mode when lock is done.
    The implementation is quite simple and does need only few digital gates.
