DesignWare Floating-Point MAC IP Implementation This document outlines the successful implementation and verification of a DesignWare Building Block (DWBB) floating-point multiply-accumulate (MAC) IP core. The following sections detail the module implementation, simulation setup, synthesis approach, and troubleshooting steps. Verilog Module Imp ...

SystemVerilog Procedural Statements and Operators for RTL Design SystemVerilog introduces several procedural statements and operators that enhance the Verilog language, enabling more concise and expressive synthesizable RTL code. These additions convey designer intent more clearly, reducing ambiguity and helping EDA tools interpret procedural s ...

Core Functionality in Verification Architectures In the Universal Verification Methodology (UVM), the transaction object acts as the primary data carrier. It abstracts low-level device-under-test (DUT) pins into structured data payloads, enabling seamless component communication through TLM (Transaction Level Modeling) channels. By embedding ra ...

Built-in Data Types While Verilog primarily uses reg and wire types, SystemVerilog (SV) introduces the logic type as a more versatile data type. // SV also provides a corresponding `bit` type. // Both `logic` and `bit` can be used to create vectors. // The key difference is: // `logic` is a 4-state type, representing 0, 1, x (unknown), and z (h ...

Conditional Compilation in Verilog ifdef is a conditional compilation directive in Verilog that enables or disables code blocks based on macro definitions. This feature is useful for platform-specific designs, debugging, and performance optimmization. Basic Syntax in Verilog-2001 `ifdef MACRO_NAME // Code included if MACRO_NAME is defined ` ...

This design establishes a standardized, reusable video data interconnect interface using SystemVerilog interface constructs. It decouples timing-critical video signaling (e.g., sync pulses and pixel data) from functional blocks, enabling modular integration, scalable testbenches, and hardware-agnostic verification. Interface Definition: video_b ...

SystemVerilog Design Hierarchy Enhancements SystemVerilog introduces numerous extensions to Verilog that significantly improve how designers represent and work with hardware design hierarchy. This article explores the key constructs that enable more efficient modeling of complex digital systems, from module prototypes to parameterized types. Mo ...

6.1 General Purpose Always Block in Verilog The always procedural block creates an infinite loop executing its contained statements repeatedly. Simulation advancement requires time controls or event controls such as delays (#), wait conditions, or event triggers (@). always @(a, b) begin sum = a + b; diff = a - b; prod = a * b; end ...

SystemVerilog introduces interface as a first-class abstraction for modeling communication channels between design blocks. Unlike Verilog’s flat port-list approach, interfaces unify signal declarations, directionality, protocol logic, and verification constructs into a single, reusable unit—enabling cleaner hierarchy, safer connectivity, and sc ...

Module Interface Overview The AXI4 Master interface consists of five distinct channels: Write Address (AW), Write Data (W), Write Response (B), Read Address (AR), and Read Data (R). Signals prefixed with M_AXI_ indicate the Master side of the interface. Specifically, AR_* signals belong to the Read Address channel, AW_* to the Write Address cha ...
