globalfoundries has 2 (actually 3 whatever) version of their 22nm node: 22FDX, and the upgraded 22FDX+. when you design semiconductor IP, you generally use the foundry's IP package in a way similar to a standard library.
Except globalFoundries are cheapskates and don't want to create that IP, so they offload that part to other companies like Synopsys, who don't really care because you're not paying them, GF is.
for 22FDX, GF comissionned IP from synopsys who delivered, but for 22FDX+, GF instead took that 22FDX package wholesale and validated it again for 22FDX+ without really asking synops…
