众所周知，用于FPGA开发的硬件描述语言（HDL）主要有两种：Verilog和VHDL。其中，VHDL的出现时间要比Verilog早，而Verilog由于其简单的语法，跟C语言的相似性，目前被各大公司广泛使用。 其实在上大学时，我学习的就是VHDL语言。后来由于公司使用的都是Verilog，于是 ...

在之前的文章中，我们讨论了使用 Verilog语言元素对组合电路的描述。本文重点介绍同步时序电路。我们将首先查看同步电路的通用模型，然后以双向计数器的 Verilog 描述为例进行讨论。 顺序电路 在组合电路中，输出仅取决于输入的当前值。然而，时序电路的 ...

Sometimes good ideas take a while to catch on in engineering practice. The use of in-line assertions to document assumptions and check for problems in RTL code is one such idea. Long ago proposed for ...

As discussed in Part 1, this article proposes four steps to raise the abstraction level of current Verilog HDL designs and provide a phase wise approach to migrate to SystemVerilog. In Part 1 we ...

SystemC 2.1 supports all hardware concepts introduced by HDLs such as Verilog and VHDL. V2SC proposes a methodology for automatic conversion of Verilog 2001 constructs into SystemC 2.1 language. This ...

For high data rate wireless communications they use Orthogonal Frequency Division Multiplexing (OFDM) due to its high spectral efficiency and low computational complexity. It gives the architecture of ...
