Verilog-2001添加了generate循环,允许产生module和primitive的多个实例化,同时也可以产生多个variable,net,tash,function,continous assignment ,initial和always。在generate语句中可以引入if-else和case语句,根据条件不同产生不同的实例。 为此,verilog-2001增加了以下关键字:generate, endgenerate, genvar, localparam。genvar...
下面我们来看下真双端口 RAM,真双端口 RAM 指的是有两个独立的读写口,就是有两组数据线和地址线,一组是读或者写数据线,另外一组也是读或者写数据线,同一个时刻两个端口可以同时访问,两个端口可以是读和读,也可以是写和读,还可以是写和写。 module dp_ram ( input clocka , //ram clk input clockb ...
I was trying to write a verilog code for a memory module which has has a bidirectional inout port for the data. But I also want to output high impedance during write or if MEM_OE(output enable) is not set. But my code as below cannot simulate ...
please i need help in how to write this in verilog, the dr advised searching the internet but i didn't find what i was looking for though there's alot of codes available maybe what i need is there but the fact that i don't get verilog is the problem! first i thought i'd implem...
