cadence acquired Build Gates from Ambit for 150M $, RTL compiler for 150M $. They must have made 10M out of both products in the past 10 years.
Cadence is a company which acquires products, more products without really translating it ever into cash for shareholders
Maybe the EDA companies are also having problem in organic growth so they acquire companies. By doing so, they also kill potential competitors, this may be a win-win situation if the new team is managed properly
Acquisition is an integral part of economy. However, for this kind of special technology development company and its engineer needs special environment to thrive. New manamgement should not disturb it. If they try to change their culture without understandnig their needs, they may not get best out of them.
