Introduction
The use of hardware description language (HDL) is becoming a more dominant factor, when designing and verifying FPGA designs. The use of behavior level description not only increases the design productivity, but also provides unique advantages in the design verification. The most dominant HDL stoday are called Verilog and VHDL. This application note will illustrate the use of Verilog in design and verification of a digital UART (Universal Asynchronous Receiver & Transmitter).



簡介
使用硬件描述語言 (HDL) 設(shè)計(jì)和開發(fā)驗(yàn)證FPGA的成為當(dāng)前的主流因素。使用行為級(jí)描述不只增加了產(chǎn)品的設(shè)計(jì)效率，也在設(shè)計(jì)中有獨(dú)特的驗(yàn)證方式。目前最流行的HDL語言為Verilog 和 VHDL。 這篇文章將會(huì)舉例說明用 Verilog語言 的設(shè)計(jì)和驗(yàn)證數(shù)字異步串行收發(fā)器UART。
