本文簡單討論并總結了VHDL、Verilog，System verilog 這三中語言的各自特點和區別As the number of enhancements to variousHardware Description Languages (HDLs) hasincreased over the past year, so too has the complexityof determining which language is best fora particular design. Many designers and organizationsare contemplating whether they shouldswitch from one HDL to another.

利用一塊芯片完成除時鐘源、按鍵、揚聲器和顯示器（數碼管）之外的所有數字電路功能。所有數字邏輯功能都在CPLD器件上用VHDL語言實現。這樣設計具有體積小、設計周期短（設計過程中即可實現時序仿真）、調試方便、故障率低、修改升級容易等特點。 本設計采用自頂向下、混合輸入方式（原理圖輸入—頂層文件連接和VHDL語言輸入—各模塊程序設計）實現數字鐘的設計、下載和調試。

UART 4 UART參考設計，Xilinx提供VHDL代碼 uart_vhdl This zip file contains the following folders: \vhdl_source -- Source VHDL files: uart.vhd - top level file txmit.vhd - transmit portion of uart rcvr.vhd - - receive portion of uart \vhdl_testfixture -- VHDL Testbench files. This files only include the testbench behavior, they do not instantiate the DUT. This can easily be done in a top-level VHDL file or a schematic. This folder contains the following files: txmit_tb.vhd -- Test bench for txmit.vhd. rcvr_tf.vhd -- Test bench for rcvr.vhd.
