New book: SystemVerilog Assertions Handbook, 4th Edition

In reply to ben@SystemVerilog.us:

Is there an e-book for this? I prefer e-book than a physical book because of the ease of searching texts and the portability of e-books. I tried to search online but only physical books are being sold. I think it’s because e-books can easily be pirate so that’s why they don’t create an e-book for it.
