System Design Software for Engineers

System Design Software

Collimator is an online system design tool that fits your applications and lets you accelerate your development process with cloud collaboration and high-performance cloud computing

“I wanted to have the flexibility that Python affords me. I also wanted to get the suite of features from other engineering simulation software. I believe [this] has enormous potential”
Academic Researcher in Control and Automation at IIT
“That is actually really cool. Having access to all my existing Python code opens up a huge number of possibilities. That is a huge benefit!”
Control Systems Engineer in Computer Electronics
“It is amazing to use Python, run on a web browser and collaborate on the cloud […] This is undoubtedly 10x better than what I've used before!"
GNC Engineer in Aerospace and Defense Manufacturing
Collimator has major improvements over Simulink plus it is in the browser so it is very portable. Collimator also feels more powerful from a computational standpoint since simulations are performed using HPC in the cloud
Mechatronic Engineer, ElektromontaĹĽ RzeszĂłw S.A.

Python GUI Library for System Design

Our system design software features an integrated development environment (IDE) with a comprehensive GUI for Python that includes thousands of built-in GUI blocks. Save time when designing the architecture, modules, and other system components
See documentation

Customizable Function Blocks for Flexibility

Collimator system design software offers almost everything you need out of the box. Customizable function blocks help facilitate your product design by tailoring the functions to your exact needs and allows you to integrate code from prior projects
See documentation

Reusable Diagram Components

This system design diagram tool with reusable function block diagram components enhances product design. Leverage and build upon prior work by using and reusing previous designs. Save time and make internal and external team collaboration easier
See documentation

Top reasons why engineers choose Collimator

Python First

Collimator is Python-based, so you have access to open-source libraries like Numpy, Tensorflow, and Pytorch. Convert Python code into C automatically using our system designer software

Cloud Based

Our software design tool’s High-Performance Compute (HPC) lets you run millions of test cases, test various scenarios, and simulate conditions difficult or expensive to reproduce in the real world

Team Efficiency

Design system software using mutual workspaces, with no more miscommunications between collaborators. Collimator improves output when you’re designing various elements of a large system

Simple Pricing

We have simple, easily understood plans for users ranging from small teams to large enterprises. With our free plan, you can try Collimator at no cost

Integrate AI & ML Tools

Because our software designing tool is built in Python, your users can easily import AI and ML tools like Pytorch, Thane and Keras and use them to test and perfect your system design

Real-time Data Streaming

The more data you have, the better. Our system designer software uses synthetic data generation to represent situations where real-world research would be too costly or simply impossible

Enhance Engineering Design with System Design Diagram Tools

Access to powerful open source libraries and a simple-to-use build GUI that enhances your engineering designs and makes collaboration easy

Modeling in Collimator


Our software designing tool can be used for Model-Based Systems Engineering and Model-Based Definition Design. Our intuitive GUI makes designing and testing complex projects easier, and gives you access to big data from your web browser

Simulating in Collimator


Building hardware prototypes always involves costs and development risks. Our system design tools let you find and correct system design issues and review various scenarios through modeling and simulation on our High-Performance Compute (HPC) cluster

Visualizing results in Collimator


Very few system designer software options give you a Graphical UI. Collimator is one of them. Collect data from multiple scenarios and use cases, then visualize it in easy to follow forms like context diagrams, E-R diagrams and flowcharts

Collaboration features and Role Based Access Control (RBAC) in Collimator


With Collimator, you can collaborate with team members from your web browser and make decisions without endless emails. Our system design software increases engineering productivity and helps you get products to market faster

Frequently Asked Questions

What is software systems design?

Software systems design is the process of outlining and building the different components of a software while ensuring that data is sent and received efficiently through the software as a whole.

What tools are used for system design?

System design tools provide an interface for system designers to manage their systems in a standardized way. Ideal system design tools will feature intuitive component drag & drop, easy team collaboration, management of version control and seamless integration with developer tools.

Which app is used for system design?

There are many apps that users turn to to meet their system design needs. System Composers by Matlab/Simulink, Ansys SCADE, and Collimator are all great tools for system design across various fields.
