Transcript of Tanner Introduction

. Tanner EDA
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

Tanner ToolsTanner 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

Tanner EDA Design ToolsS-edit - a schematic capture tool

T-SPICE - the SPICE simulation engine integrated with S-edit

L-edit - physical design tool

W-edit - waveform formatting. Tanner EDA

S-EDITS-Edit is a powerful design capture & entry tool that can generate netlists directly usable in T-Spice simulations.Provides an integrated environment for editing circuits, setting up and running simulations and probing the results.It also provides the ability to perform SPICE simulations of the circuitThese circuits that can be driven forward into a physical layout.

L-EDITL-edit refers to Layout EDITor Flexible to do micromachining design, PCB layout, and other CAD work.L-Edit/DRC -it indentifies any design faults (widths, spacing, overlaps)L-Edit/Extract- generates a circuit "netlist" , which is used for SPICE simulation

W-EDITNot just a waveform viewer but a robust analysis tool

Built-in measurements like max, min, average, intersect, rms, over/undershoot, amplitude, error, crossing, delay, frequency, rise/fall time, settling time, duty cycle, slew rate, etc.

Easy measurements by selecting traces & applying options.. Tanner EDA

T-SPICEIt is a complete design capture and simulation solution that provides accuracy.The role of T-Spice is to help design and verify a circuits operation.T-Spice simulation results allow circuit designers to verify and fine-tune designs before submitting them for fabrication.Performs fast, accurate simulations for analog and mixed-signal IC designs and fully supports foundry models for reliable and accurate simulations. .

T-SPICE vs SPICET-Spice uses an extended version of the SPICE, compatible with all industry-standard SPICE simulation programs.

Speed: T-Spice provides highly optimized code for evaluating device. It also provides the option of table-base transistor model evaluation which yields dramatic increase simulation speed. Tanner EDA

Continued..,Convergence: TSpice uses advanced mathematical methods to achieve superior numerical stability as in Spice.Accuracy: T-Spice uses very accurate numerical methods and charge conservation to achieve superior simulation accuracy.Macro-modeling: It supports black box macro devicesExternal model interface: It allows custom device models using C or C++.The analysis results for voltages, currents, charges, and power can be written to single or multiple files.

Continued..,DC operating point analysis finds the circuits steady-state condition.

DC Transfer Analysis is used to study the voltage or current at a set of points in a circuit as a function of the voltage or current at another set of points. This is done by sweeping the source variables.. Tanner EDA

. Tanner EDA
Continued..,AC Analysis characterizes the circuits behavior dependence on small signal input frequency.

Transient Analysis provides information on how circuit elements vary with time.

Power up mode: For circuits without DC steady state (difficult to specify their initial state), the power up option of the .tran command. It sets entire circuit to zero for time equal to 0.
