IEEE Std 1364-2005(即verilog-2005)版本则修订更正并澄清了verilog-1995版和verilog-2001版中描述不明确的功能。它还解决了 IEEE 1364-2001 与 IEEE 1800™-2005 (即SystemVerilog-2005)标准不兼容和不一致的问题。 在接下来学习verilog的博文之前,博主先在本篇对Verilog HDL语法的国际统一格式(BNF:Backus-Naur ...

Hardware description capabilities: SystemVerilog extends the Verilog hardware description language (HDL) with new constructs for more efficient and concise hardware modeling, such as enhanced data types, structs, and unions. Assertions and functional coverage: SystemVerilog includes built-in constructs for...
HDLint : A power full linting tool for VHDL and Verilog. nLint : nLint is a comprehensive HDL design rule checker fully integrated with the Debussy debugging system. SureLint : Designers need tools to analyze and debug their designs before integrating with the rest of the project. SureLint ...
The basic lexical conventions used by Verilog HDL are similar to those in the C programming language. Verilog HDL is a case-sensitive language. All keywords are in lowercase. White Space White space can contain the characters for blanks, tabs, newlines, and form feeds. These characters are ign...
Cadence now has full proprietary rights to Gateway's Verilog and the Verilog-XL, the HDL-simulator that would become the de facto standard (of Verilog logic simulators) for the next decade. Originally, Verilog was only intended to describe and allow simulation, the automated synthesis of subsets...
Sign in to download full-size image Figure 5-19.Levels of abstraction (Verilog versus VHDL). Mixed-language Designs Once upon a time, it was fairly common for an entire design to be captured using a single HDL (Verilogor VHDL). As designs increased in size and complexity, however, it be...
aVerilog HDL是一种应用广泛的硬件描述语言,可用于从算法级、门级到开关级的多种抽象层次的数字系统设计。 Verilog HDL is one kind of application widespread hardware description language, available in from algorithm level, gate level to switch level many kinds of abstract level number system design. [...
Icarus Verilog is intended to compile ALL of the Verilog HDL, as described in the IEEE-1364 standard. Of course, it's not quite there yet. It does currently handle a mix of structural and behavioural constructs. For a view of the current state of Icarus Verilog, see its home page at ...
