Why Cadence not revealing their prices for their software product?
Cadence does not make money with educational licenses, however they support universities because they often cooperate with the industry and train future engineers.

For commercial use license costs depend on the number of licenses you buy and of course can be negotiated. For academic use the license costs are very small and are more like a "handling fee". I live in Europe and the prices for academic software can be found here. This should give you a rough idea what prices to expect.

These academic prices are very low compared to commercial prices, therefore you need to make sure that they are only used for educational purposes. For example you have to keep track of the license usage, the people who have access to the software and keep record of this information for at least five years!

The "University Software Program" is available in many locations, details can be found here

So, keep in mind that you are more an academic partner than a customer (unless you are willing to shell out a few 100k for a single seat license package) and give it another try.
