Block diagram and GUI

for System Design

Collimator brings together a comprehensive GUI with Python so engineers can efficiently design their systems, reduce their development risk and bring products to market faster.


Comprehensive GUI for Python

Users can use pre-built function blocks to model their systems in discrete, continuous and hybrid domains. These function blocks span multiple use cases including aerospace and defense, automotive, communications, electronics, Internet of Things (IoT) and manufacturing
See documentation

Customizable function blocks for flexibility

Users can create their own domain specific functionality using our Python function block. This function block can also be used to bring in pre-written code from prior products or be used to access open source libraries including Numpy and Scipy
See documentation

Reusable function block diagram components

Users can aggregate their function block diagrams into subsystems and share subsystems across projects. This feature allows engineers to collaborate across internal and external teams
