我们再来看看systemverilog-2005里面定义的Event Regions。 我第一次看到内心其实也是崩溃的,卧槽,数了下,总共有17个Event Regions。但是,如果把8个PLI(Programming Language Interface,用来调用其它语言的函数的接口,比如C/C++)的Event Regions剔除,看上去也还好。 Active

SystemVerilog作为当今主流的硬件设计和验证语言,其精确的事件调度机制是保证仿真确定性的核心。本文将结合具体示例,深入剖析SystemVerilog的调度原理,揭示其背后的分层时间推进模型。 核心概念:事件驱动仿真 SystemVerilog仿真器本质是一个离散事件驱动的模拟引擎,其核心是通过动态更新的事件队列(Event Queue)来模拟硬件行为。
SystemVerilog time slot 时间片 概要 Regions that are designed to implementcorrect RTL functionality: Active regions (Active, Inactive and NBA regions - but avoid Inactive region events). Regions that are designed to implementcorrect verification execution: Preponed, Reactive regions (Reactive, Re-Inacti...
There are groups of event regions that are used to help define the scheduling of System Verilog activity. Active region:Events scheduled in the Active, Inactive, Pre-NBA, NBA, and Post-NBA regions are active region set events. Reactive region:Events scheduled in the Reactive, Re-Inactive, Pre...
The Verilog HDL language was utilized to discretize the continuous system through an enhanced Euler method, and the resulting output was presented on an oscilloscope. Finally, a summary of the entire paper was provided in the conclusion section. 2. NGMSCS with two nonlinear functions Prior to ...
SystemVerilog 2017 Pre-processor, Parser, Elaborator, UHDM Compiler. Provides IEEE Design/TB C/C++ VPI and Python AST API. Goal This project aims at providing a complete SystemVerilog 2017 front-end: a preprocessor, a parser, an elaborator for both design and testbench. We are aiming at ...
Most of the modules were implemented in hardware, using Verilog HDL, taking full advantage of the possible parallelization and pipeline, which allowed to obtain real-time image processing. The ARM processor is responsible for executing some parts of the algorithm, i.e. high-level image processing...
SARATOGA has two execution units connected to separate ports on the register file. Both are copies of the same Verilog module however some functionality is left unconnected (and thus optimized out) in execution unit 1. Each execution unit takes in two values from the register file during EXEC0...
A SystemVerilog description consists of connected threads of execution or processes. (SystemVerilog是由一系列相关联的进程所组成的。进程(Processes)是SystemVerilog中并发调度的单元,比如:原语(Primitives)、initial过程块、always过程块、连续赋值(continuous assign)、异步任务(asynchronous tasks)、过程赋值(procedural...
