Altium Designer Altium Designer is an EDA software solution that provides the designer with the tools they need to solve engineering problems and create the electronic devices that change the world. Support for Flex and Rigid-flex Design. Enhanced Layer Stack Management. Support for Embedded Components. Altium Designer helps you navigate the process of creating new and innovative electronics using Flex and Rigid-flex circuits. A layer stack manager allows for the definition and naming of primary and sub-stacks on a circuit board for use in a Rigid-flex circuit design. Embedding important components within the layers of a circuit structure creates faster, more reliable products that are smaller and have lower production costs.
