From the article "AMD Spartan UltraScale+ samples and evaluation kits are expected to be available for sampling and evaluation in the first half of 2025." For hardware products, what is the point of making these announcements a year in advance? Are they available for select partners before 2025?

When you need to decide on what FPGA line you are going to base your products on, you certainly want to know years in advance what new models will obsolete your FPGA products. However, you don't just want to know their specifications but also their price.

This is kinda true.

But the flip side is most of them tell you ahead of time whether something is recommended for new designs, and how long they will guarantee production for.

Which is much more important.

In this day and age with FPGA companies being merged and spun out left and right, i doubt anyone relies on the future line announcements this second.

In more normal times I agree you want to know if you are going down a dead end path.

If you know your product needs these features you can do early prototyping and development on similar or higher end platforms and then switch to this new platform when it becomes available.

Having knowledge of upcoming parts is important in hardware engineering for planning purposes.

Oh, yes. Hardware products and projects, specially those complex enough to need an FPGA, will usually have a long development pipeline and even one year seems pretty short.

And you can very often prototype with either an overpowered development board or you own prototype board with another FPGA, and then downsize appropriately as the project advances. Most importantly, if you know there will be a viable version in a year, you can postpone the final decision and Xilinx get to avoid having you choosing Altera now if it's possible that their new offering will match your project.

Do companies really gamble on their supply chain that hard?

[blihp]

They don't have a choice. FPGA's aren't like vanilla logic chips: they are highly proprietary both in terms of their specific hardware functionality as well as software tool chains and you can't second source them. Some of the larger customers are using them for government contracts (think military and space applications) where they are signing up products they are contractually on the hook for from years to decades.

[willis936]

Yes I know. So any product being developed today or in the next year would be done on a well established option that will be produced for many more years. It still isn't clear to me why such a long runway on the announcement does for anyone. It shouldn't be changing anyone's plans.

[guepe]

Yes they are.
