While looking for information on a Xilinx Spartan 6 Project with DDR memory I came across a new type of DRAM called the Hybrid Memory Cube (HMC). The technology made me want to take a closer look:
The Hybrid Memory Cube is like a stack of DDR chips stacked die on die using through silicon vias to interconnect the dies the bottom die in not… Read More
We all like compliments, correct? You know the kind that go like, “Glad you didn’t screw that up”. From time to time I get, “You write what you do because you’re affiliated with Xilinx”. Perhaps I will name my next child Xilinx. I have said this before, I do real work (debatable) and trade studies,… Read More
Dear Reader, I need your help with something.
Invention is the Mother of necessity. When I bought the Miller Farm, it came with a very shallow well. What that meant is priming the pump, alot. Me being an engineer weighed the options. The wife, with 5 kids to bath, wash clothes, cook, etc.. was a bit overwhelmed. Of course the worst day… Read More
Go ahead – type “open source” into the SemiWiki search box. Lots of recent articles on the IoT, not so many on EDA tools. Change takes a while. It has only been about five years since the Big Three plus Aldec sat down at the same table to work on UVM. Since then, Aldec has also gotten behind OS-VVM, and is now linked to a relatively new open… Read More
The IoT (Internet of Things) creates an ambivalence within me. Part of me hates computers and being connected, the other is currently working on a boiler controller that even adaptively predicts and senses when the next wood load is needed and alerts the wife. Yup pray for her. I really use FPGAs and CPLDs around the farm and I am slowly… Read More
One of the things I do in my spare time is listen to quarterly conference calls and try to sort fact from fiction. I compare past calls to the current one and attempt to predict what’s coming next. Confucius said, “Study the past if you would define the future” and I’m a big believer in that.
Paul McLellan wrote about the Xilinx call earlier… Read More
Xilinx announced their results today and had their conference call this afternoon, which I listened to. For them this is 1Q fiscal 2015 which means you have to be careful since there is a big difference between talking about fiscal quarters and calendar quarters. Xilinx’s conference calls are interesting for a couple of … Read More
FPGAs in many ways are still a bit mysterious to some folk. I was at a high level summit in April, and I realized that many there had no idea what an FPGA was. They knew at least what a CPU was or meant and that their kids talk about GPUs. A good analogy I have for an FPGA when compared to a CPU is something like this. Think of the FPGA and CPU as … Read More
Reading Intel analysis lately has been a lot like reading fantasy baseball analysis. Intel should buy Altera. Intel should waive Atom. Intel should fab for Apple. All of those have a near-zero probability of happening IMHO, and yet pundits continue to pitch their version of alternate reality, dealing away product lines and strategies… Read More
Vector blasting hardware is as old as digital test methodology itself. In the days of relatively simple combinational and finite state machine logic, a set of vectors aimed broadside at inputs could shake loose most faults with observable outputs. With FPGAs, creating an effective set of artificial test vectors has become a lot… Read More
