DAC 2020: Chips in 2030

By Paul McLellan | 3 Aug 2020

In 2015, soon after I rejoined Cadence, I went to IEDM, the International Electron Devices Meeting. That year it was in Washington DC. I paid for most of the trip myself since I'd already booked the flights and hotels months in advance to get goo...

DAC 2020: TSMC Keynote

By Paul McLellan | 31 Jul 2020

The opening keynote at DAC was TSMC's Chief Scientist Philip Wong. That's clearly not nearly enough work, so he's a professor at Stanford, too. As I said in my post DAC Preview 2020 , I've seen a version of this presentation befor...

DAC 2020: Open-Source EDA

By Paul McLellan | 29 Jul 2020

The Department of Defense (and actually much of aerospace in general) is in an especially difficult place as regards access to silicon. Their production volumes are so low. This means they don't get great pricing from foundries, especially as mo...

Open Source Hardware

Open-source software has revolutionized many aspects of software development. But I believe it has a business-model problem. It is largely successful in supply chains where someone wants to "commoditize their complements". It reminds me of ...

Photography of Computers

By Paul McLellan | 8 Jul 2020

In the early days of computers, I think computers were generally just called "computers". They occupied air-conditioned rooms with raised floors and were typically the size of several large (modern) refrigerators. The main long-term storage...
