good comprehensive broad review of PDK. Perhaps additional chapter on content of these PDK collaterals as part of foundry enablements, such as tech files for AMS/SoC/adv package, evolution of pcells that now include many fundry process "preference" of rules, electrical and physical signoff files etc ... Each will require some kind of certification, and tsmc has been leading the industry for years, although most of design teams take foundry recommended flow as reference at the beginning of new node ramp
1. Thanks for the nice overview, I found it really helpful (and a good reminder)!
2. Is the name of (ir-) responsible executive at Intel known, who decided to skip the HTOL testing for Raptor Lake? Reason I am asking is that the testing budget involved (~ $100K) is low enough that it likely wouldn't have required sign-off by the CEO. My suspicion is that skipping HTOL was less about the small savings, but more about meeting a deadline.
3. Your statement about delays in Nvidia's Blackwell also being due to chiplet design and bump-outs puzzled me. The Blackwell die is (AFAIK) still a monolith, albeit close to the upper limit of what TSMC's reticles allow. Or were you referring to the connections to HBM and the ARM CPUs in the AI accelerators?
Love your articles wpuld have loved to find you sooner which would have prevented me from making ultra stupid decisions if your info is mostly correct
I know your articles are not financial advice and I sound like a idiot
So a few months ago I thought hey TSMC being the go to foindry is priced kn let's buy samsung and intel instead and so I bought 3 EWY(Korea ETF high Samusng weightage and some hynix too) and 22 INTC shares. Thankfully this was money I could fully lose and I am only 5% down
Forgot to mention there are is a upside you mentioned to Samsung in other articles like Micron and hynix ceos belive Samsung finally has figure out hbm so that's good but I invested mainly for Samsung foundry which is a dumpster fire according to most news outlets

THANK YOU SO MUCH!!
Been 20 years since I had a Pierret class. Thanks for the panic attack 🤣
