Tätigkeitsbeschreibung

ADPLL Digital Radio SXM Tuner Project, 4.3GHz.
- Responsible for the creation and maintenance of the self-checking AMS RF behavioral models involved in the design along with their verification and validation against schematic and spec
- Executing Top-Level AMS simulation and verification using a makefile based on irun, assertions (sva and psl), monitors, checkers and the self-checking Verilog-AMS wreal models
- Running Connectivity Checks using amsDmv PinCheck to compare the module interface and pin declarations of the wreal models against the reference design (schematic, symbol and layout)
- Using irun and amsDmv to create fully digital regression simulation scripts and reports
- Modeling Design for Testability behavior (DFT) to be used in top-level verification
- Using Verilog-AMS Real Number approach (wreal) to model following blocks:
SBAND Tuner, Low Noise and Transimpedance Amplifiers (LNA and TIA), Quadrature Signal Generator, I and Q Mixers, 1st order LPF, Slew Rate Control, Clippers, Level Detectors, Wide Band Dual ADC, 4th order Sigma Delta Modulator, Cristal Oscillator with Phase Noise Jitter, Antenna Supply, Temperature Sensor with Bandgap Temperature Curve, Shielded Lines, Low Dropout Regulators, Low Frequency Divider, Voltage and Bias Current Generator, ATB MUX
- Deciding which functionality is relevant for top level functional verification and implementing the models accordingly keeping in mind the trend-off between speed and accuracy
- Running top transistor-level simulation and migrating to a Mixed-Signal simulation flow by replacing key blocks with their respective models to speed up the performance
- Running IP transistor-level simulation e.g. SBAND Tuner to investigate the deviation with respect to the IC Specification Document
- Using advanced DSP and RF theory concepts for creation of the models and the top level simulation: sampling with 4 times the maximum input frequency to achieve a fast simulation while avoiding aliasing effects (Nyquist). This applies for all the blocks.
- Using the Bilinear Transformation to convert the continuous transfer function (s-domain, laplace transform) of a Low Pass Filter with specific characteristics in a discrete transfer function (z-domain) and using warping to reduce and compensate the effects of aliasing as the input approaches the Nyquist frequency
- Using ViVA to plot the Spectrum (Discrete Fourier Transform, Hamming Window) of the LPF output when a sum of sinusoidal signals is applied to the input in order to obtain the Bode Diagram of the phase and magnitude
- Converting complex 4th order Sigma Delta Modulator’s matlab model into Verilog-AMS (wreal)
- Using matlab post-processing to compare Verilog-AMS and Matlab Model’s response by analyzing the Noise Quantization Spectrum
- Using SMG (Schematic Model Generator) to support and automate the creation of models
- Using AMS Designer, ADE-XL, irun, schematic testbench, Hierarchy Editor and amsDmv (Analog Mixed-Signal Design Model Validate) to validate the behavioral model against the transistor-level design in an mixed-signal environment as well as creating amsDmv regression simulations
- Customizing Connect Rules for Mixed-Signal simulation (adjusting vsup, vdelta, vtol, currentmode for current ports, idelta, itol, input and output impedances, rise and fall time, etc)
- Using Interface Element/IE-card based setup (OSS/UNL) to customize the Connect Modules
- Creating an executable script .sh to synchronize models located in coReuse and OA databases
- Creating AMS Model Specification documents in DOORs using the IC Design Specification and the transistor-level design (schematic) as a reference
- Creating Model Sign-Off documentation which includes “AMS Model versus AMS Model Specification” and “AMS Model versus Schematic” validation based on fully digital and mixed-signal simulation results obtained from regression scripts
