Shhhhh.....SpectreRF Tutorials and AppNotes - One of Our Best Kept Secrets!
By Tawna Wilsey on February 9, 2009


Did you know that we have hidden a wide variety of SpectreRF Tutorials, Workshops, and Appnotes in your MMSIM hieararchy?
In your <MMSIM71>/tools/spectre/examples/SpectreRF_workshop directory there are the following  tutorials, appNotes, and workshops:


RF Workshop Tutorials
The RF Workshop Tutorials  show how to simulate typical RF circuits such as LNAs, Mixers, VCOs, and PAs in spectreRF.  Note that the database is in cdba (not oa, open access).  The RF Workshop HB Tutorials show similar simulations using the new HB, HBAC, and HBNoise analyses available in MMSIM 7.1.
See rfworkshop_hb.tar.gz and rfworkshop.tar.gz

RF Measurement Library:
Modern RF systems require designers to perform different RF measurements, such as second and third-order intercept points, for a large number of design variations. This tutorial describes how to use and create measurement cells in the RF measurement library flow, including:
1. How to perform several measurements at the same time
2. How to reuse the measurements for different designs
The measurement-based simulation is easier to perform than an analysis-based simulation and is commonly used by other simulators in industry.   The measurement aware approach allows you to place multiple measurements on a schematic.    It also allows you to customize analyses and outputs to a greater extent than is currently possible in ADE.
See tutorial measurement_workshop.tar.gz and accompanying document RFMeasurementLibraryTutorial.pdf

Signal Partitioning Workshop:
The Signal Partitioning workshop describes how to speed up SpectreRF harmonic balance simulation by using signal partitioning for special circuit designs.  Signal partitioning provides a method of decomposing a circuit so that multi-rate
behavior can be exploited to increase simulation performance.     SignalPartition_71.pdf

ODFM Workshop:
The ODFM AppNote and Workshop shows how to setup and run a simulation that uses the ODFM module in MATLAB and Spectre.  Orthogonal Frequency-Division Multiplexing (OFDM) is a digital multi-carrier modulation scheme in which closely-spaced sub-carriers are summed into a main carrier. The sub-carriers are orthogonal to each other and modulated with conventional modulation schemes at a low symbol rate. The summation is performed using Fast Fourier Transforms.
OFDM is robust against both intersymbol interference and narrow-band cochannel interference. It is spectral-efficient. OFDM is used in applications such as WiMAX, MBWA, Wi-Fi, and UWB.
See files:  OFDM_tutorial.pdf    and     ofdm.tar.Z

GFSK Tutorial:
The Gauss Frequency Shift Keying (GFSK)  tutorial demonstrates how to set up and run a simulation using the GFSK
module. The exercise begins by demonstrating the setup for MATLAB, then continues by illustrating the setup for Spectre.
At the end of the tutorial is a summary of information about the terminals and parameters of the GFSK module.
See files: GFSK_tutorial.pdf and gfsk.tar.Z

SpectreRF Simulink Workshop:
This tutorial and appNote explain how to do high level system concept design using SpectreRF and MATLAB/Simulink, thus combining the best of system-level simulation with lower-level analog and RF simulation. Simulink provides large libraries of DSP algorithms for generating complicated signals and post processing while SpectreRF supports transient and envelope analysis of common RF and communication circuits, such as mixers, oscillators, sample and holds, and switched capacitor filters at both the transistor and behavioral levels.

See files:  SpectreRF_simulink_example.pdf and  SpectreRF_simulink_example.tar.Z

SpectreRF Noise Aware PLL Flow
The SpectreRF Noise-Aware PLL Design Flow is described in the following document:  PLL_701.pdf

In the SpectreRF_AN directory, there are the following appNotes and databases:
1. Perturbation Based Measurements appNote and database:  PerturbationAN.pdf and Perturbation.tar.gz.  
2. Harmonic Balance release notes HB_AN.pdf.  
3. Envelope Following Analysis appNote and workshop database:  EnvelopeAN.pdf and Envelope.tar.gz.
4. Jitter Measurement appNote:  JitterAN.pdf.
5. Power Supply Rejection Ratio Characterization Using Spectre RF for Driven Circuits:   PSRR_Drv_AN.pdf.
6. Power Supply Rejection Ratio Characterization Using Spectre RF for Autonomous Circuits:  PSRR_Osc_AN.pdf.
7. Large Signal S-Parameter Wizard appNote and workshop: LSSP_AN.pdf and LSSP.tar.gz.
8. Periodic Stability analysis using PSTB appNote and workshop: PstbAN.pdf and Pstb.tar.
9. Noise Separation in Pnoise/Qpnoise Analysis appNote: NS_AN.pdf.
10. Spectre/RF Matlab toolbox for Spectre/SpectreRF/Ultrasim appNote and workshop: MatlabAN.pdf and MatlabWorkshop.pdf.
11. Using Verilog-A Baseband Models of RF Blocks appNote and database: RF_Blocks_AN.pdf and RF_Blocks.tar.gz.
12. Long Term Jitter Measurements appNote:  LTJM_AN.pdf.
13. PLL Jitter Measurements appNote: PLL_Jitter_AN.pdf.
