Verilog 中一些低级内置门基元的 VHDL 等效项可以通过使用逻辑运算符如 NOT、AND、NAND、OR、NOR、XOR、XNOR 来实现。 下面是 Verilog 门基元的 VHDL 等效代码示例: or u1(x,y,z); in Verilog <=> x <=< span=""> y OR z; in VHDLand u2(i1,i2,i3); (Verilog) <=> i3 <=< span=""> i...

但是,在底层硬件建模方面,Verilog优于VHDL。这是合理的,因为 Verilog 最初是为建模和模拟逻辑门而创建的。事实上,Verilog 具有内置原语或低级逻辑门,因此设计人员可以在 Verilog 代码中实例化原语,而 VHDL 则没有。 Verilog 的门基元:and、nand、or、nor、xor、xnor、buf、not、bufif0、notif0、bufif1、notif1、...
What is the difference between Verilog and VHDL? On the surface, not that much. Both are IEEE standards and are supported by all the major EDA vendors. Both can be used for designing ASICs and simulating systems. However, VHDL is altogether a grander language. Its support for system level...
> typing has made a real difference in my work... at least an > improvement. I think Andy has it about right. If you think signed arithmetic was a tad messy in VHDL, wait until you find how successfully you can be screwed by Verilog. The really cool thing is that Verilog is...
What are the difference between Verilog and VHDL? What are system tasks? List some of system tasks and what are their purposes? What are the enhancements in Verilog 2001? Write a Verilog code for synchronous and asynchronous reset? What is pli? why is it used?
How are Verilog and VHDL different from each other? Elaborate on the term HDL Simulators. What is the difference between == and === in Verilog? Tell me the five basic differences between Verilog’s task and function. What is Continuous Assignment? Explain how Verilog Repeat Loop works. Defin...
在VerilogHDL中调用VHDL的模块 最近忽然要用到在VerilogHDL中调用VHDL的模块,从网上找了例程,把自己会忘掉的东西记在这里,. 2选1多路复用器的VHDL描述:entity mux2_1 is port( dina : in bit; dinb : in bit; sel : in bit; dout : out bit );end mux2_1; architecture Behavioral of mux2_1 is...

The only difference is that the ++ and -- operators are not supported in Verilog. Instead of writing i++ as you would in C, you need to write out its full operational equivalent, i = i + 1. 1 for (i = 0; i < 16; i = i +1) begin 2 $display ("Current value of i is ...
