Understand your Code

Have you recently inherited confusing legacy code? Understand is here to help.

Analyze Dependencies

Blindly changing legacy code can lead to disaster. Know what your changes will affect before you even start writing.

Navigating legacy code doesn't need to feel like an endless maze. Quickly navigate references to create a mental map of the code base.

View Call-Trees

Expand a function's call tree to see what any changes might affect. You can also view Butterfly, Control Flow, and many other useful graphs.

Verify your Code

Does your project require strict coding standards? Understand has the capability to check your code against industry, common, or custom standards.

Introducing CodeCheck, our code compliance solution

CodeCheck can be integrated into your CI/CD pipeline to run with every code check-in and notify team members when a compliance check has failed.

Checks against industry standards like Autosar and MISRA C/C++

Our Bug Hunter checks look for common bugs like memory leaks and dangling pointers Learn More

Let our trained software engineers write your custom standards for you! Learn How

Customizable Rules

All rules come standard with every installation of Understand.

Compare your Code

Quickly see the difference between two project states. View changes by files, folders, entities or architectures. View your changes as a text comparison or in a tree map. Just specify the git revision you would like to compare against or compare two databases.

GRAPHS

Visualize your Code

Quickly see how your source code is structured, organized, and related. See Control Flow, Call Trees, Dependency, Butterfly, UML Class, and many other graph types. All our graphs are interactive and customizable, expand or contract your graph to see exactly what you need.

Quantify your Code

Do you need help locating the "problem" areas in your code? Understand comes bundled with dozens of metrics that help with exactly this scenario.

Measure Twice, Code Once

Understand your code's cyclomatic complexity by using various browser and display options

Receive detailed metrics about your code at the file, class, and entity levels

Export a full list of your metrics to an HTML or CSV file

Automate your Code

Do you prefer complete control over your coding environment? Understand comes bundled with a robust API to unlock your project's full potential.

An API for Toolsmiths

Our API allows the creation of custom graphs, metrics, and lexical analysis. Integrating with your current tools is now easier than ever! Learn More

Continuous Integration

Verify code compliance, ensure code complexity stays below a specified threshold, or email the team a code comparison graph all from your existing pipeline. Learn More

Custom Scripting

Create and enforce any custom coding standard. We can teach you how to write a standard or simply hire us to handle the entire process for you! Learn More

Explore your Code

Navigating complex code relationships has never been easier. Hyper-Xref technology and the tools in Understand make you a safer, smarter engineer less likely to add bugs as you change code.

Understand contains a built in IDE that facilitates code browsing. Click on any entity (function, class, variable, etc) to see detailed information and double click to be taken directly to where the entity is defined. Every named part of your code is referenced and can be bi-directionaly navigated.

Keep the Information Browser pinned while you work to quickly see everything Understand knows about a selected entity. The Information Browser updates depending on what you have selected.

For functions, see the return type, paramters, and a list of references that take you to that instance immediately when clicked.

For files, see the member variables and functions, a list of includes, and relevant metrics.

Graphs can also be accessed from the Information Browser or by right clicking any named entity in your code. Quickly see everything that calls or is called by a specific funtion with a Butterfly Graph.

Explain your Code

Give your new engineers the tools they need to succeed. Understand helps onboard new engineers rapidly and safely.

Understand is certified in ISO 26262, IEC 61508, and EN 50128

Understand by Scitools is certified for use as a support tool for all projects requiring ISO 26262, IEC 61508, and EN 50128 compliance. Safety is our top priority at Scitools, our software is heavily tested and vetted before each release providing your team with a safe and secure development environment.
