The common way of categorizing RFID tags is based on how they utilize power for communication between the reader and the tag. They can also be classified based on operating frequency and absence/presence of chips. This first part of the FAQ will cover the passive, semi-passive, and active RFID tags categorized based on power. Types […]
FAQ
What is a PLL for analog signals?
A phase-locked loop (PLL) for analog signals generates an output with a phase that’s precisely matched to the phase of an input reference. Analog PLLs are widely used in high-frequency applications like communication systems and scientific equipment that need low jitter and precise synchronization. This article begins by looking at how PLLs for analog signals […]
How AI and ML optimize functional verification for EDA
Functional verification ensures that the register transfer layer (RTL) implementation of semiconductor designs operates according to specified requirements. Electronic engineers typically perform functional verification using hardware verification languages (HVLs) such as SystemVerilog paired with the universal verification methodology (UVM). Other HVLs, such as VHSIC Hardware Description Language (VHDL) and Property Specification Language (PSL), may be […]
What is formal verification, and why is it important?
Formal verification uses mathematical analysis to ensure semiconductor designs perform as intended. Typically automated, it efficiently identifies critical design errors, such as deadlocks, race conditions, and unreachable states. This article reviews the fundamentals of formal verification in semiconductor design, explores its integration with simulation for comprehensive validation, and highlights strategies for optimizing implementation. Defining formal […]

How hardware-assisted verification (HAV) transforms EDA workflows
Many semiconductor companies rely on hardware-assisted verification (HAV) to optimize sophisticated monolithic system-on-chip (SoC) designs and chiplet architectures. HAV streamlines verification and validation by integrating emulation, field-programmable gate array (FPGA) prototyping, and virtual platforms. This approach enables design engineers to efficiently verify individual components and system-wide interactions while validating functionality at granular and system-wide levels. […]
Parasitic extraction in EDA: what it is and why it matters
Parasitic extraction (PEX) in electronic design automation (EDA) calculates parasitic effects — such as capacitances, resistances, and inductance — within integrated circuits (ICs). Parasitics are introduced during the physical manufacturing process in semiconductor foundries, affecting both IC devices and their interconnects (Figure 1). This article explores the three primary categories of parasitic effects, compares field […]
What are the different types of AI accelerators?
Whether in data centers or at the edge, artificial intelligence (AI) accelerators address the limitations of traditional von Neumann architecture by rapidly processing massive datasets. Despite the gradual slowing of Moore’s law, these accelerators efficiently enable key applications such as generative AI (GenAI), deep reinforcement learning (DRL), advanced driver assistance systems (ADAS), smart edge devices, […]
What is the voltage standing wave ratio (VSWR) in RF systems?
Voltage Standing Wave Ratio (VSWR) is a fundamental parameter that measures the efficiency of radio frequency (RF) power transmission from a source through a transmission line to a load. A simple way to measure VSWR is to find the highest to lowest voltage ratio in a standing wave created on a transmission line due to […]
