eFPGA Gives You FPGA Speed And Density At Much Less Cost And Power
By Geoff Tate - 07 Dec, 2023 - Comments: 0

FPGAs are everywhere in all types of systems for their flexibility and quick time to market. As your volumes grow and you consider an ASIC to cut cost and power, you can now incorporate an embedded FPGA to continue to give you flexibility for the parts of your chip that need to adapt for changing standards, improving algorithms and customer optimizations. If you are an SoC designer, you c... » read more

Overcoming The Challenges Of Capacitive Touch HMI Design
By Vibheesh Bharathan - 07 Dec, 2023 - Comments: 0

The capacitive touch human-machine interface (HMI) is a critical aspect of modern electronics. It is how we interact with our devices, making it an integral part of wearables, smart home products and IoT products. The primary goal of an HMI is to provide an intuitive and responsive interface that supports human interaction. However, designing a touch HMI system that meets the consumer's expecta... » read more

Understanding Memory Protection Units
By Ashwin Kumar - 06 Nov, 2023 - Comments: 0

Let’s talk about the various security measures we take to protect our homes. We use locks, install security cameras to detect any suspicious activities, etc., all to safeguard our loved ones and valuable possessions. In similar sense, the tiny microcontrollers inside our devices have protection units (PU) that safeguard the precious resource: memory. One of the most important types of prote... » read more

Securing AI/ML Training And Inference Workloads
By Bart Stevens - 02 Nov, 2023 - Comments: 0

AI/ML can be thought about in two distinct and essential functions: training and inference. Both are vulnerable to different types of security attacks and this blog will look at some of the ways in which hardware-level security can protect sensitive data and devices across the different AI workflows and pipelines. The security challenges encountered with AI/ML workloads can be addressed by i... » read more

Designing Automotive ICs For Cybersecurity
By Mohammed Abdelwahid - 02 Nov, 2023 - Comments: 0

The day has already arrived when we need to be concerned about the cybersecurity of our cars. An average modern car includes about 1400 ICs and many of them are used in sophisticated applications, like autonomous driving and vehicle-to-everything (V2X) communication. The security of road vehicles is an important issue to automakers and OEMs but is rooted in the IC devices that power the vehicle... » read more

Verifying Compliance During PCIe Re-Timer Testing Poses Challenges
By Kunal Chhabriya - 02 Nov, 2023 - Comments: 0

In PCI Express (PCIe), a high-speed serial computer expansion bus standard, Compliance mode is used for testing the transmitter and interconnect to assess if their voltage and timing are compliant with the specification. This testing happens in the Polling Compliance state which is a dedicated state for Compliance testing in the Link Training and Status State Machine (LTSSM). In Unraveling the... » read more

Closing The Performance Gap Between DRAM And AI Processors
By Balaji Kanigicherla - 02 Nov, 2023 - Comments: 0

As the workhorse of semiconductor memory, DRAM holds a unique place in the industry thanks to its large storage capacity and ability to feed data and program code to the host processor quickly. Lately, this unsung hero of the circuit board has been taking a backseat to its logic counterparts, as a wave of high-performance FPGAs, CPUs, GPUs, TPUs and custom accelerator ASICs emerges to meet t... » read more

eFPGA Architectural Improvements That Lower Test Cost And Increase Quality
By Geoff Tate - 02 Nov, 2023 - Comments: 0

More than 40 chips have been licensed to use EFLX eFPGA and >20 chips are working in silicon. Big customers like Renesas are planning high volume families of chips using embedded FPGA. As a result, we have gained extensive experience and knowledge in almost 10 years of doing eFPGA especially in production test for cost reduction and reliability improvement. eFPGA DFT and MBIST for high q... » read more
