Using Formal For RISC-V Security


Finding and closing up security holes is becoming more important as chips are used in safety- and mission-critical applications, but it's increasingly important for chips designed for much less costly devices, where the selling price typically doesn't warrant a significant investment in security. The problem is these devices are connected to some of the same networks, and any access points for ... » read more

RISC-V’s Software Portability Challenge


Experts At The Table: RISC-V provides a platform for customization, but verifying those changes remains challenging. Semiconductor Engineering discussed the issue with John Min, vice president of customer service at Arteris; Zdeněk Přikryl, CTO of Codasip; Neil Hand, director of marketing at Siemens EDA (at the time of this discussion); Frank Schirrmeister, executive director for strategi... » read more

RISC-V Conformance


Experts At The Table: Despite growing excitement and participation in the development of the RISC-V ecosystem, significant holes remain in the development flow. One of the most concerning is conformance, which must exist before software portability becomes possible. Semiconductor Engineering discussed the issue with John Min, vice president of customer service at Arteris; Zdeněk Přikryl, CTO... » read more

Blog Review: Oct. 9


Siemens’ Stephen Chavez looks at the key benefits and challenges to achieving a successful ECAD-MCAD collaboration. Cadence’s Nayan Gaywala shares the AXI4 locking mechanism when implementing an Xtensa LX-based multi-core system on a Xilinx FPGA platform, using a dual-core design mapped to a KC705 platform as an example. Synopsys’ Vincent van der Leest digs into SRAM PUFs and their ... » read more

Corner-Case Bug Hunting for RISC-V


By Ashish Darbari and Ia Tsomaia RISC-V continues to make headlines worldwide, but verification continues to be challenging. The findings of the Wilson Research Report, 2022 (see figure 1) make the trends in verification clear. We presented these in a keynote talk titled, "Future is Formal," at the recent DVCon India event. One thing is quite apparent: whether you are using directed tests... » read more

Chip Industry Week In Review


Infineon rolled out the world's first 300mm gallium nitride (GaN) wafer, opening the door for high-volume manufacturing of GaN-based power semiconductors. A 300mm wafer contains 2.3 times as many chips per wafer as a 200mm wafer. Fig.1: Infineon's 300mm GaN wafer.

As EDA Processes Becomes More Secure, So Do Chips


Security is becoming a much bigger concern within chips and electronic systems, but the actual implementation remains something of an afterthought, which limits its effectiveness. There are many pieces to the security puzzle on the chip design side that go well beyond just securing the hardware or the IP. The EDA tools themselves need to be secure, as well, and so does the user data within t... » read more

Insights From The AI Hardware & Edge AI Summit


By Ashish Darbari, Fabiana Muto, and Nicky Khodadad In today's rapidly changing technology landscape, artificial intelligence (AI) is more than a buzzword. It is transforming businesses and societies. From advances in scalable AI methodology to urgent calls for sustainability, the AI Hardware & Edge AI Summit recently held in London, sparked vibrant discussions that will determine the fu... » read more

Changes In Formal Verification


For the better part of two decades, formal verification was considered too difficult to use in many designs and too slow for anything but narrow bug hunting. Much has changed recently. Ashish Darbari, CEO of Axiomise, explains why formal is now essential for finding deadlocks, security holes, and Xprop issues in mission-critical, safety-critical, and AI designs, and how that will apply to chipl... » read more

Verification Tools Straining To Keep Up


Verification engineers are the unsung heroes of the semiconductor industry, but they are at a breaking point and desperately in need of modern tools and flows to deal with the rapidly increasing pressures. Verification is no longer just about ensuring that functionality is faithfully represented in an implementation. That alone is an insolvable task, but verification has taken on many new re... » read more
