	1	1	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.
	2	2	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.
	3	3	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.
	4	5	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.
	5	7	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.
	6	13	Layout versus Schematic (LVS) Debug In ASIC physical implementation, once layout is generated, it must follow all the design rules for successful manufacturing and must match the schematic of the required design. To ensure this in physical verification, Design Rule Check (DRC) is carried out to check whether the layout follows the rules for fault-less manufacturing or not.
	7	15	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.
	8	9	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.
	9	New!!!	An Outline of the Semiconductor Chip Design Flow his article provides an overview of the chip design flow, its different stages, and their contributions toward creating an effective chip. These stages include system specifications, architectural design, functional design, logic design, circuit design, physical design verification, and manufacturing.
	10	19	Synthesis Methodology & Netlist Qualification The main objective of this article is to explain synthesis flow and post-synthesis netlist quality checks. In ASIC flow, synthesis is the part of the front-end design, while the back-end design takes the synthesized netlist as an input. So, the synthesized netlist should meet all netlist quality checks to reduce multiple iterations, which reduces the turnaround time and efforts.
	11	10	Demystifying MIPI C-PHY / DPHY Subsystem The newest member of the MIPI® PHY family, the C-PHY, arrived in October 2014 to a mixture of excitement and apprehension. How would this new C-PHY compare to the MIPI D-PHY and M-PHY®? What would differentiate the C-PHY, and would it be compatible enough with the D-PHY so that both could coexist in a hybrid subsystem? Now, years later, the answers are clear.
	12	18	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.
	13	6	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.
	14	8	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.
	15	New!!!	Power analysis in 7nm Technology node This article discusses the power analysis of a complex 7nm networking chip. As the next-generation System on a Chip (SoC) moves toward the future, the chip size decreases with a simultaneous increase in the number of switching transistors to meet the demand for better functionality.
	16	4	UPF Constraint coding for SoC - A Case Study This paper deals with the implementation of UPF for low power SoC design that can encompass several vendor IPs and custom IPs UPF constraints.
	17	New!!!	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.
	18	14	Floorplan Guidelines for Sub-Micron Technology Node for Networking Chips Overall, floorplanning is an important stage in physical design because it directly impacts the performance, power consumption, and area utilization of the final chip. A well-executed floorplan can significantly reduce design iterations and shorten time-to-market, making it an essential step in the chip design process.
	19	20	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.
	20	17	Artificial Intelligence and Machine Learning based Image Processing Image processing is the process of converting an image to a digital format and then performing various operations on it to extract useful information. When certain predetermined signal procedures are used, the image processing system typically treats all images as two-dimensional signals.
