Compute eXpress Link (CXL) is an open standard that allows a) Host to access externally connected pool of DDR memory space with simple load/store commands at low latencies. b) A host server to expand its memory map to acquire DDR space statically or dynamically as per program requirements. c) Devices like GPGPU that sit outside the system to…

While Register Transfer Level (RTL) simulation plays a vital role in verifying the high-level functionality of a design, it is often insufficient to catch all potential issues. This is where gate-level simulation (GLS) steps in as an important verification step, providing a more detailed and realistic view of the design's behaviour before it is sent…

Onboard Charger (OBC) Integrated Circuits (ICs) are critical components in electric vehicles (EVs), responsible for managing power conversion and battery charging. Verifying these ICs is essential to ensure functionality, reliability, and compliance with automotive standards. This article discusses the key aspects of OBC IC verification, including methodologies, challenges, and best practices. 1. Role of Onboard…

What is AMS Verification: Analog Mixed Signal (AMS) refers to simulations that utilize both analog and digital solvers. In the context of integrated circuit (IC) design, AMS verification involves testing and validating analog and mixed-signal ICs as per the design requirements. AMS designs combine both analog components (e.g., amplifiers, filters, oscillators) and digital components (e.g.,…

AMS & DMS in VLSI Verification Analog Mixed Signal (AMS) and Digital Mixed Signal (DMS) are both crucial areas in the verification and validation of integrated circuits, but they differ significantly in their nature and the expertise required for each. Analog Mixed Signal (AMS) AMS refers to the combination of analog and digital components within…

Direct Programming Interface (DPI) is a mechanism that allows System Verilog to call functions or tasks written in C/C++ and vice versa. DPI enables the integration of custom C/C++ code with System Verilog, facilitating advanced verification tasks that are difficult or inefficient to achieve purely in HDL. Key Features Lightweight interface. No need for PLI/VPI (Programming Language Interface/Verilog Procedural Interface). Simplified interaction between hardware design and software simulation environments. Importance of DPI in ASIC Verification Enhanced Verification Capabilities: DPI allows the use of existing C/C++ models or libraries for complex computations and data handling. Performance Optimization: Enables faster execution of time-consuming algorithms compared…
