Downloading SVEditor 1.9.6.1 for Mac from the developer's website was possible when we last checked. We cannot confirm if there is a free download of this app available. We recommend checking the downloaded files with any free antivirus. The software lies within Design & Photo Tools, more precisely Viewers & Editors. The actual developer of this free Mac application is Matthew Ballance.
From the developer:
SVEditor is an Integrated Development Environment that allows you to easily edit SystemVerilog and Verilog files. The program comes with an intuitive interface and provides you with advanced features for code editing. Syntax is checked as you type, alerting you to errors before launching a full compile. The tool automatically indents your code as you type. It fixes indentation of a file, or segment of a file, at the touch of a button.
You may want to check out more Mac applications, such as Cuadro or Resize Now, which might be similar to SVEditor.
