Just as an addition and confirmation:

I once contacted Synopsys to learn a little more about this cooperation:

Here the answer:

Hello Dr. ...,

We received your inquiry about the release noted below. I can confirm that Poet Technologies issued a release about their Synopsys collaboration with our approval. You’re correct that Synopsys doesn’t have additional information about this collaboration on our website.

Best regards,
Sheryl Gulizia

To me it is clear that POET is still in stealth, but slowly and carefully lefting the curtain. They know very well when and how to proceed.
