用合成的ROM内核模拟一个简单的测试台
我对FPGA领域是一个全新的领域,并认为我将从一个非常简单的项目开始:一个4位7段解码器。我纯粹用VHDL编写的第一个版本(基本上是单个组合select,不需要时钟),并且似乎可以使用,但我也想尝试使用Xilinx ISE中的“ IP内核”功能。 因此,现在我正在使用“ ISE Project Explorer” GUI,并使用ROM内核创建了一个新项目。生成的VHDL代码为: LIBRARY ieee; USE ieee.std_logic_1164.ALL; -- synthesis translate_off LIBRARY XilinxCoreLib; -- synthesis translate_on ENTITY SSROM IS PORT ( clka : IN STD_LOGIC; addra : IN STD_LOGIC_VECTOR(3 DOWNTO 0); douta : OUT STD_LOGIC_VECTOR(6 DOWNTO 0) ); END SSROM; ARCHITECTURE SSROM_a OF SSROM IS -- …
