Intento Design is a new EDA company offering software that accelerates the development, reuse and migration of analog and mixed-signal integrated circuits. The company's tool is ID-Xplore, which can sit after a open-access analog IP database such as might be used with Cadence's Virtuoso and ahead of Cadence's Spectre analog simulator. Using ID-Xplore, designers input the desired parameters of complex analog functions, and explore schematic options to achieve the right balance of performance, power consumption and robustness for a wide range of connected applications. Typical circuits include amplifiers and reconfigurable filters. Intento Design was founded in 2015 and is based in Paris, France.

Thalia Design Automation provides tools for optimizing analog, mixed signal and power designs via the automation of design cycles and production. Its electronic design automation tools aim to simplify and speed up design processes of electronic chips.
