Verilog-A Parser Documentation
Overview
This documentation provides guidance on using the Verilog-A Parser. This parser is designed to handle the analog portion of the Verilog-AMS language, which is commonly used for creating analog, and mixed-signal models. For full documentation of the Verilog-A language see verilogams.com. The parser facilitates the extraction of the Abstract Syntax Tree (AST) from Verilog-A source files, which can be further utilized for analysis, simulation, or conversion purposes.
Installation
Before using the Verilog-A Parser, ensure that the CedarSim
package, which includes the VerilogAParser
, is installed in your Julia environment. You can install CedarSim
using Julia's package manager.
using Pkg
Pkg.add("CedarSim")
Usage
To parse a Verilog-A file and obtain the AST, follow these steps:
Importing the Module
First, you need to import the CedarSim
package, specifically the VerilogAParser
module.
using CedarSim: VerilogAParser
Parsing a File
To parse a Verilog-A file, use the parsefile
function provided by the VerilogAParser
. You need to specify the path to your Verilog-A file as an argument to this function.
ast = VerilogAParser.parsefile("path/to/your/verilogA_file.va")
This function reads the specified Verilog-A file and parses it to construct the AST.
Example
Here's a simple example of how to use the Verilog-A Parser to parse a file and print a summary of the AST:
# Import the necessary module
using CedarSim: VerilogAParser
# Specify the path to your Verilog-A file
filename = "example.va"
# Parse the file to obtain the AST
ast = VerilogAParser.parsefile(filename)
# Print the AST to the console
println(ast)
This script will output the structure of the AST, which provides insights into the parsed elements of the Verilog-A file.
Conclusion
The Verilog-A Parser in Julia provides a powerful tool for handling the parsing of analog Verilog-AMS models. By converting Verilog-A code into an AST, users can perform a wide range of tasks from analysis to simulation, enhancing the flexibility and utility of Verilog-A model handling in Julia.
