[sdiy] Yamaha CS-60 issues

[john slee]

How do they plan for obsolescence of FPGA parts? Is the lifecycle of a
typical FPGA long enough that it's not a big deal?

Presumably FPGAs are selected for some relevant criteria and replacing one
with another would require revalidation of the product. I guess that's
still likely to be cheaper than maintaining stock of ancient spare silicon,
or worse, restarting manufacture.
