Pros
Cadence is one of the leading EDA providers. If you are in the EDA industry or looking for a job in EDA, it is one of the very few options available. The company is well run, has a good compensation and benefits package and has been voted on of the top 100 companies to work for by fortune magazine. The work is challenging as most EDA problems require good algorithm skills in solving complex chip design problems.
Cons
It is not the company but the industry which is the issue here. Although demand for EDA tools will always exist, EDA seems to be a flat to shrinking business which chip designs getting more and more expensive. Cadence and competitor Synopsys have been trying to diversify to other adjacencies with limited success over the years.
