	1	1	Is your career at RISK without RISC-V? I am delighted to share my technical insights into RISC-V in this article to inspire and prepare the next generation of chip designers for the future of the open era of computing. If you understand how we build complex electronic devices like desktops and smartphones using processors, you would be more interested in learning and exploring the Instruction Set Architectures.
	2	2	Dynamic Memory Allocation and Fragmentation in C and C++ In C and C++, it can be very convenient to allocate and de-allocate blocks of memory as and when needed. This is certainly standard practice in both languages and almost unavoidable in C++. However, the handling of such dynamic memory can be problematic and inefficient. For desktop applications, where memory is freely available, these difficulties can be ignored. For embedded - generally real time - applications, ignoring the issues is not an option.
	3	3	System Verilog Macro: A Powerful Feature for Design Verification Projects SV macro is one of the most powerful features out there and if used properly with a thorough understanding and applied wisely in a DV project, it can help to save a lot of time and can make the code more readable and efficient. This paper shows how, using SV macro with the proper syntaxes, a DV engineer can break up the larger complex code in smaller chunk and can reuse it at many places.
	4	4	System Verilog Assertions Simplified Assertion is a very powerful feature of System Verilog HVL (Hardware Verification Language). Nowadays it is widely adopted and used in most of the design verification projects. This article explains the concurrent assertions syntaxes, simple examples of their usage and details of passing and failing scenarios along with waveform snippets for the ease of understanding.
	5	6	Design Rule Checks (DRC) - A Practical View for 28nm Technology The main objective of this paper is to explain the various types of design rule checks (DRC) violation, their causes and how to fix the various design rule checks (DRC) at lower technology node on block level as well as full chip level implementation while meeting the design rule with respect to latest technology standards.
	6	10	PCIe error logging and handling on a typical SoC This paper details first PCIe errors, error logging and then the error handling on a typical SoC.
	7	5	UVM RAL Model: Usage and Application To cope with the speed of the competitive market landscape, most of the systems are designed in a generic way - which means the same design can be used in different ways with different configurations. More the number of configurations, more the number of registers in the design.
	8	7	Using SystemVerilog Assertions in RTL Code SystemVerilog Assertions are not difficult to learn; in this tutorial, you will learn the basic syntax, so that you can start using them in your RTL code and testbenches.
	9	9	Method for Booting ARM Based Multi-Core SoCs In the boot process various modules/peripherals (like clock controller or security handing module and other master/slaves) initialized as per the SoC architecture and customer applications. In Multi core SoCs, first primary core (also called booting core) start up in boot process and then secondary cores are enabled by software.
	10	14	Efficient Verification of RISC-V processors Processor verification, however, is never trivial but requires combining the strengths of multiple verification techniques. This technical paper considers how to efficiently verify a RISC-V processor using a multi-layered approach known as the Swiss cheese model adapted from the world of avionics.
	11	8	A Review Paper on CMOS, SOI and FinFET Technology In 1958, the first integrated circuit flip-flop was built using two transistors at Texas Instruments. The chips of today contain more than 1 billion transistors. The memory that could once support an entire company’s accounting system is now what a teenager carries in his smartphone. This scale of growth has resulted from a continuous scaling of transistors and other improvements in the Silicon manufacturing process.
	12	11	Scan Chains: PnR Outlook At times physical design engineers find it difficult to relate with the additional timing modes introduced in PnR due to DFT insertion. These additional timing modes and related issues could be handled more efficiently if we understand why a scan chain is needed and how it works.
	13	New!!!	Usage of Multibit Flip-Flop and its Challenges in ASIC Physical Design The continuous need for reduced size of the chip in the VLSI industry brings exciting challenges to the layout engineers for designing better and high-performing integrated circuits, which needs to consume low power even while reducing the silicon area and cost involved. Internal power is a component of the total power consumed by the chip, which is becoming more challenging to handle with the shrinking technology nodes.
	14	New!!!	Multimedia Intelligence: Confluence of Multimedia and Artificial Intelligence In contrast to traditional mass media, such as printed material or audio recordings, which feature little to no interaction between users, a multimedia is a form of communication that uses a combination of different content forms such as audio, text, animations, images, or video into a single interactive presentation.
	15	New!!!	Understanding Shmoo Plots and Various Terminology of Testers Nowadays, engineers are focusing more on testing, as device size/logic is becoming large. The designs are becoming complex with time and thus testing is becoming challenging in terms of time and cost both. To cater good yield, different test and vectors are provided by DFT engineers.
	16	15	Understanding Logic Equivalence Check (LEC) Flow and Its Challenges and Proposed Solution Formal verification techniques have been developed using mathematical proof rather than simulation or test vectors to provide a higher level of verification confidence on properties. For example, the implementation can be either a Verilog RTL module or an abstract version of a particular design, while the specification is typically a set of properties that needs to be verified and expressed suitably. So, formal verification provides a complete verification of each specification property under considering corner cases even without test vectors.
	17	New!!!	Antenna Effect in 16nm Technology Node This paper describes the antenna effect observed in the 16nm design and the way to identify antenna violations in design using different PV tool. We have described three different methods to fix the violations.
	18	19	Congestion & Timing Optimization Techniques at 7nm Design This article discusses about the various approaches to reduce congestion and timing violation by modifying floorplan at block level.
	19	New!!!	Why using Single Root I/O Virtualization (SR-IOV) can help improve I/O performance and Reduce Costs In this paper, we will explore why designing systems that have been natively built on SR-IOV-enabled hardware may be the most cost-effective way to improve I/O performance and how to easily implement SR-IOV in PCIe devices.
	20	12	A Guide on Logical Equivalence Checking - Flow, Challenges, and Benefits This white paper functions as a guide, outlining why LEC (Logical Equivalence Check) is important in the ASIC design cycle, how to check it, and what to do when LEC is failing.
