Development, as part of the ANR-Blanc MOOREA project, of: (I) an organic memristor (variable resistor with memory states) compact model for neuroinspired applications. The compact model is intended to be used by the project designers in neuroinspired demonstrators’ electrical schematics in a standard CAD tool (here, Cadence Virtuoso). The demonstrators must highlight the advantages of the memristor technology over the current CMOS technologies for neuroinspired applications regarding: the performance, the integration density, the power consumption, the lifetime, the data retention time... The compact model reproduces the behaviour of the physical organic memristor. It is derived from the physical filament-type conduction mechanism, and from electrical characterizations and parametrical extractions performed on test structures in pulsed mode. (II) an innovative dynamical approach in order to the compact model have a non-volatile characteristic between two successive simulations. The approach relies on a complementary tool chain and a circuit description organization. Pots-simulation data are retrieved by simulating a circuit netlist in the Spectre format and are processed by a PERL program. The circuit netlists contain instances of the compact model. Afterward, the PERL program generates an output file, in which the compact model parameters are updated, to be included in the netlists. Such approach is especially useful for circuit electrical schematics containing a huge number of compact model instances. Show less

Development, as part of the CATRENE/3DIM3 European project, of: (I) predictive RLCG compact models for interconnects used in novel 3D integration technology, including TSV (Trough-Silicon-Via), derived from the Transmission Line Method (TLM), electromagnetic simulations and parametrical extractions performed on test structures. These models are proposed because many challenges are encountered with 3D technology since it is emerging, notably to properly characterize and model electrically the 3D interconnects. In addition, few present-day CAD tools allow designing 3D architectures. (II) a 3D extraction tool using Matlab, 3D-TLE (3D Transmission Line Extractor), based on our modeling approach. The main challenge in 3D technology is that the global electrical context must be considered (coupling effects between components or with the substrate, current paths...) to accurately design 3D systems and evaluate their performance. Systems descriptions can therefore become rapidly complex and tedious. 3D-TLE lifts this issue by proposing to designers to depict, in an input text file, their circuits according to their geometrical and technological data by means of a hierarchical syntax and specific statements. The users also specify the possible interactions of the system components with their environment. The 3D extraction tool generates, as an output file, a netlist of the system in the SPICE format. This netlist is easily exportable towards standard CAD tools (Cadence Virtuoso ADS). Show less

Development of a simulation tool, ELSID, enabling the identification and the order reduction, of electrical linear systems (such as cables, interconnect networks, circuit pin) from their representative matrices (H, Y, S…). The reduced model, by being incorporated in standard CAD tools, decrease CPU times. The reduced models keep the input/output characteristics of the investigated physical systems and so reproduce their behaviours and performances. Electrical linear systems can be either defined with Matlab description files or designed under CAD tools and electromagnetic simulators for which frequency data are then exported. Show less

Development of an analytical model for 2D interconnects to investigate the characteristics of crosstalk voltages generated by coupled effects between neighbouring lines of a digital circuit interconnects network. The model is based on: the quasi-TEM propagation modes existing in interconnection lines networks; the dissociation on the crosstalk voltage waveform between the capacitive and inductive coupled effects; and a correlation method enabling a description of the considered global network with 1st and 2nd order analytical expressions. The proposed model can be easily incorporated in simulation tools to reduce CPU times. Show less

Design of a high current power supply (250A) for an Automated Test Equipment ATE Sapphire model. At first, design of the high current power supply and the DUT (Device Under Test) board. Then, modeling of the test pins and cables linking the power supply with the DUT board to take into account of the capacitive and inductive coupled effects (between elements, between the different ATE functional blocks) due to the ATE working in the high frequency domain. It was demonstrated that to reproduce the ATE performance, it was required to model in its equivalent electrical schematic the coupled effects. Thanks to the coupled effects modeling, the designers have been able to understand, in high frequency, phenomena occurring on the physical ATE responses (such as crosstalks on the voltages delivered by the power supply). Consequently, they have been able to propose design solutions to limit or suppress these undesired effects. Show less
