A Compilation of EDA and Semiconductor IP Company Merger Listing All the Logos a Company Owns
This list is a compilation over many years of mergers and acquisitions in the EDA and Semi IP market. The original compilation was done by an individual (Ian Getreu [1]) and is not an official list associated with any company or organization. Companies that have not bought or merged with other companies are not included in the list.

There is no guarantee of accuracy or completeness. Mergers and acquisitions that were not announced via press releases are probably not included. We welcome any additions and corrections.

The original objective was simply to list the number of logos owned by a company. So, if company A bought company B and was then bought by company C, this would be listed via indentations as:

Company C

Company A​

Company B​
