When situation demands, multiple solutions appear with a slight lag of time. Similar is the story with estimating and optimizing power at SoC level. In the SoC era, power has become a critical criterion long ago, and there are tools available for power analysis and optimization. However, with more mobile and IoT (Internet of Things)… Read More
In a power hungry world of semiconductor devices, multiple ways are being devised to budget power from system to transistor level. The success of IoT (Internet of Things) Edge devices specifically depend on lowest power, lowest area, optimal performance, and lowest cost. These devices need to be highly energy efficient for sustained… Read More
It’s been the case most of the time that until we hit a bottleneck situation, we do not realize that our focus is not at the right spot. Similar is the case with power analysis at the SoC level. Power has become equally if not more important than the functionality and other parameters of an SoC, and therefore has to be verified earlier … Read More
Last month in DAC I could see some of the top innovations in the EDA world. EDA is a key enabler for advances in semiconductor designs. Among a number of innovations worth mentioning (about which I blogged just after DAC), the integration of Mentor’s Veloce with ANSYS’ PowerArtist for power analysis of live applications caught my… Read More
As the number of CPU, GPU, and IP is growing in an SoC, power management is becoming more and more a complex task in itself. A single tool or methodology may not be enough for complete power management and verification of an SoC. In an SoC, there can be multiple modes of operations involving hardware and software interactions, different… Read More
Today, an SoC can have multiple instances of an IP and also instances of many different IPs from different vendors. Every instance of an IP can work in a separate mode and requires a dedicated power arrangement which may only be formalized at the implementation stage. The power intent, if specified earlier, will need to be re-generated… Read More
At the Samsung theatre (cutely named the Samsung Open Collaboration (SoC) theater) I watched a presentation by KK Lin on using DFM to bring up their 14nm and 10nm processes. And yes, they are real. Here is a picture I took of a 14nm wafer and a 10nm wafer. Samsung announced that they would ramp 10n to volume production by the end of next… Read More
Although I knew about Crossfire’s capabilities for signing off quality of an IP before its integration into an SoC, there was much more to learn about this tool when I visited Fractal Technologies booth during this DAC. The complexity handled by this tool to qualify any type of IP for its integration into an SoC can be imagined by the… Read More
At the most basic level, semiconductor design is all about transistors. Any report on a large microprocessor or mobile application processor is in awe about how many transistors it contains. Moore’s Law is all about the most economic way to manufacture transistors. Each process generation for the last decade and looking ahead… Read More
Most of what is talked about on SemiWiki is silicon design. After all for regular SoCs it is the only game in town. But for high voltage power applications (think automotive for one big market) there are other more esoteric technologies becoming more attractive.
Silicon has been the material of choice for high-voltage power applications… Read More
