Length: 2 Days (16 hours)

Course Description

In this two-day course, you can explore an in-depth approach to behavioral modeling of analog and mixed-signal design blocks and systems. Firstly, you examine digital modeling concepts and later analog and mixed-signal modeling concepts. You can create parameterized Verilog-AMS models for analog and mixed-signal blocks and verify their functionality and performance using the Spectre^® AMS Designer Simulator in the Virtuoso^® environment or the Xcelium™ Mixed-Signal Simulator environment.
As optional modules, you can identify how to handle analog interdependencies, modeling in the frequency domain, and the Waveform Specification (wave) feature in the ADE Assembler environment for validating models, along with basic information on the Waveform Viewers like the Virtuoso Visualization and Analysis and SimVision graph windows to examine the mixed-signal simulation results.

Learning Objectives

After completing this course, you will be able to:

• Apply the concepts of behavioral modeling and know when to employ models to your advantage
• Create Verilog, Verilog-A, and Verilog-AMS behavioral models to perform the given functions
• Verify the functionality and performance of the models that you create using the Spectre AMS Designer Simulator
• Generate a library of common functions for smoothing discontinuous behavior and model common analog effects
• Explore some of the best practices for modeling analog components
• Interpolate with table models and explore the different system tasks and functions in Verilog-AMS

Software Used in This Course

• Spectre AMS Designer
• Spectre Circuit Simulator
• Spectre Accelerated Parallel Simulator (APS)
• Xcelium Single Core
• Xcelium Mixed-Signal App
• Virtuoso ADE Explorer
• Virtuoso ADE Assembler
• Virtuoso Visualization and Analysis XL
• SimVision™ Waveform Display

This course uses Xcelium 24.09-s001 with IC 23.1 ISR10 and SPECTRE 24.1(Base) softwares. The lab exercises cover both the command-line control-based model with the XRUN executable (AXUM) and the Virtuoso-based flow (AVUM), which uses Text Editors for coding and performs simulation using Spectre AMSD in the ADE Explorer.
