Analog Modeling with Verilog-A

Length: 3 days (24 Hours)

Digital Badge Available

Course Description

In this course, you use the Virtuoso^® ADE Explorer and Spectre^® Circuit Simulator to simulate analog circuits with Verilog-A models. Verilog-A is a high-level language that uses modules to describe the structure and behavior of analog systems and their components. You use the Verilog-A syntax, structure Verilog-A modules, and generate symbols for your Verilog-A cells for use in a system hierarchy. You also learn to format output data and to use waveform filters to improve simulation performance. Finally, you examine the AHDL Linter feature to detect potential bugs in the Verilog-A codes.

Learning Objectives

After completing this course, you will be able to:

• Determine the importance of the top-down design methodology for accelerating complex system development
• Write behavioral models of electrical circuits using the correct Verilog-A language and syntax
• Create, edit, and simulate a variety of analog models written in the Verilog-A language using the Virtuoso ADE Explorer and the command-line environment
• Verify that Verilog-A modules properly describe the intended function
• Use software design tools to facilitate model development
