合理的使用宏可以大大简化我们在使用SystemVerilog编写代码的工作量,如果你不熟悉宏的使用,不仅降低写代码的效率,同时在阅读别人写的代码时也会产生诸多困惑,这里的例子将揭开`, `", `\`"这些宏中常用的符号的含义以及如何使用它们的神秘面纱。 我们还将探索UVM源代码中的一些宏,并建立编写宏的风格指南。 在我们开始之前有一个警告

systemverilog中位向量系统函数有如下五个: 1、**\$countbits( expression , control_bit { , control_bit }** 此函数\$countbits()的作用是计算位向量中指定的01x z的数量;返回值位一个整数,这个整数就是指定的control_bit的数量。 例如: \$conutbits(expression, '1),返回表达式中1的数量; ...
SystemVerilog Assertions Part-IV Jan-7-2025 Sequences Sequence Layer uses the boolean layer to contruct valid sequence of events. The simplest sequential behaviors are linear. A linear sequence is a finite list of SystemVerilog boolean expressions in a linear order of increasing time. The linear ...

When coding state machines in Verilog or SystemVerilog, there are a few general guidelines that can apply to any state machine: If coding in Verilog, use parameters to define state encodings instead of‘definemacro definition. Verilog‘definemacros have global scope; a macro defined in one modul...
Why don't you open the .xpr file (using "open_project fae_test_chip2z.xpr") in the GUI, and take a screen capture of the "Sources" window as well as the "Properties" of one of your SystemVerilog and the package file. With those, we may be able to figure out what is being ...
