But I could not find the product information at Cadence official website. Would anyone pls advise whether Cadence PSD has been renamed or discontinued?
PSD stands for "PCB Systems Division". No, the products haven't been discontinued.
In the past, all the products from that division were distributed on a set of CD's that carried a product revision number such as: 14, 15, 15.1, etc. The individual products contained on the disk set had their own revision numbers, such as 0rcad 10. Your purchased license(s) would give you access to the appropriate products from the disks.
Yes, Design Studio is on the PSD disk set. PSD 15.1 is the latest version of Cadence PSD. There is an update, but Cadence changed the name of everything in the update.
The latest update is called SPB 15.2 (Silicon-Package-Board), and the new name for "Design Studio" is "Allegro PCB Design 200 Series". Some of the stuff included in the PSD 15.1 disk set is not included in SPB 15.2.
No, I'm not an expert. I do consulting work, and I'm exposed to many different EDA and simulation products.
Some customers use Cadence PSD products. I can do the basic functions with most of their software. I don't use Cadence software for design, but I do edit/check/modify/translate designs that customers have done using various products from PSD.
