TANNER EDA SELF LEARNING TUTORIAL- PART I

Why Tanner?
  • Low total cost of ownership :It is a software platform that is cost-effective and easy to use
  • Technological innovation: It's design tools are significantly less expensive.
  • Flexible PC-based solutions.

Tanner EDA is a suite of tools for the design of integrated circuits. Tanner EDA is mainly used to analyze circuits at switch level & gate level. These are tool used to
  •  enter schematics
  •  perform SPICE simulations
  •  do physical design (i.e., chip layout)
  •  perform design rule checks (DRC) and layout versus schematic (LVS) checks.

Tanner EDA Design Tools:
  • S-edit       - a schematic capture tool
  • T-SPICE    - the SPICE simulation engine integrated with S-edit
  • L-edit       - physical design tool
  • W-edit     - waveform formatting
 
Improve simulation accuracy with advanced modeling features
                T-Spice provides extensive support of behavioral models using Verilog-A, expression controlled sources, and table-mode simulation. Behavioral models give you the flexibility to create customized models of virtually any device. T-Spice also supports the latest industry models, including the transistor model recently selected as the next standard for simulating future CMOS transistors manufactured at 65 nanometers and below—the Penn State Philips (PSP) model. PSP will simplify the exchange of chip design information and support more accurate digital, analog, and mixed-signal circuit behavior analysis.
  • Enables easy creation of syntax-correct SPICE through a command wizard.
  • Highlights SPICE Syntax through a text editor.
  • Provides Fast, Accurate, and Precise options to enable optimal balance of accuracy and performance.
  • Enables you to link from syntax errors to the SPICE deck by double clicking.
  • Supports Verilog-A for analog behavioral modeling, allowing designers to prove system level designs before doing full device level design.
  • Provides “.alter” command for easy what-if simulations with netlist changes. Perform sophisticated analysis

Sophisticated Analysis
      T-Spice uses superior numerical techniques to achieve convergence for circuits that are often impossible to simulate with other SPICE programs. The types of circuit analysis it performs include:
  • DC analysis (DC Operating Point Analysis & DC Transfer Analysis.)
  • AC analysis               
  • Transient analysis with Gear or trapezoidal integration.
  • Noise analysis.
  • Monte Carlo analysis over unlimited variables and trials.
  • Virtual measurements with functions for timing, error, and statistical analysis.
  • Parameter sweeping using linear, log, discrete value, or external file data sweeps.
  • Transient Analysis, Power-up Mode.
