Even digital designers need to be aware of how noise impacts their circuits because most clocked designs today use a Phase Locked Loop (PLL) block which contains a circuit called a Voltage Controlled Oscillator (VCO) that is quite sensitive in operation to the effects of noise and process variation. As process node scaling continues… Read More
The Status and Future of FDSOI
I recently took a look at the current status and future direction of FinFET based logic processes in my Leading Edge Logic Landscape blog. I thought it would be interesting to take a similar look at FDSOI and to compare and contrast the two processes. My Leading Edge Logic Landscape blog is available here.… Read More
CEO Interview: Xerxes Wania of Sidense
This is the first in a series of CEO interviews and I thought semiconductor IP would be a great place to start. Xerxes Wania is the President and CEO of Sidense, a leading developer of Non-Volatile Memory (NVM) One-Time Programmable (OTP) IP cores. Sidense has been a part of SemiWiki since 2013 so we know them quite well. I hope the rest… Read More
We Don’t Need Graphic Design. We Do Need Graphic Views
Many years ago, there were attempts to (re-) introduce a graphical entry approach to building RTL design. The Renoir product was one example. The idea has some initial appeal. You describe the behavior in a small block using (textual) RTL but the larger structure of instances and higher-level connectivity can be described as a … Read More
Customized PMICs with OTP in automotive and IoT
Power. Every device needs it. Managing it properly can make all the difference between a device people enjoy using and one that is more hassle than it is worth. What happens between the battery and the processor is the job of the power management integrated circuit (PMIC).
Why are PMICs gaining so much attention? Increased power … Read More
A New Player in the Functional Verification Space
Israel has a strong pedigree in functional verification. Among others, Verisity (an early contributor to class-based testbench design and constrained random testing) started in Israel and RocketTick (hardware-based simulation acceleration), acquired more recently by Cadence, is based in Israel. So when I hear about an … Read More
Are Your Transistor Models Good Enough?
SoC designers can now capture their design ideas with high-level languages like C and SystemC, then synthesize those abstractions down into RTL code or gates, however in the end the physical IC is implemented using cell libraries made up of transistors. Circuit designers use simulation tools like SPICE on these transistor-level… Read More
SoC QoS gets help from machine learning
Several companies have attacked the QoS problem in SoC design, and what is emerging from that conversation is the best approach may be several approaches combined in a hybrid QoS solution. At the recent Linley Group Mobile Conference, NetSpeed Systems outlined just such a solution with an unexpected plot twist in synthesis.
The… Read More
Dragging RTL Creation into the 21st Century
When I was at Atrenta, we always thought it would be great to do as-you-type RTL linting. It’s the natural use model for anyone used to writing text in virtually any modern application (especially on the Web, thanks to Google spell and grammar-checks). You may argue that you create your RTL in Vi or EMACS and you don’t need no stinking… Read More
SMART sensors with OTP memory for the IIoT
A few years back before IoT became the buzzword, the industrial automation community had already talking about “smart sensors” since the mid-1990s. The impetus for those discussions was IEEE 1451, a family of standards for adding intelligence and wireless communications to sensors so they could be incorporated into field networks.… Read More
