本文是基于我写的一个培训材料，内容除了没有寄存器模型以及一些大型环境中需要用到的配置文件，其他的都有涵盖。下面我将会从以下四个方面简单分享。
1，UVM introduction
2，UVM TB Tree
3，UVM TB elements
4，UVM TB example
一，UVM introduction
What is UVM?
UVM is abbreviation for Universal Verification Methodology ,it is evolution from OVM, which is Open Verification Methodology. A new generation of verification methodology jointly developed by Cadence, Mentor and Synopsys.
UVM is mainly used to verify the digital logic circuits whether meet the specification requirements.
UVM is a library based on the system verilog platform , provides a series of interfaces , make it easier for engineers to develop.

下面是本文例子中需要用到的时序图
写时序
读时序
UVM 各个组件
1.interface:简单理解就是环境与DUT时序通信用到的组件
interface exp_if (input bit clk);// single clock
logic reset_n; // here is the timing list
logic [17:0] exp_addr_i;
logic [3:0] exp_d_i;
logic exp_ceb_i;
logic exp_rwb_i;
logic [3:0] exp_q_o;
logic exp_dv_o;
logic exp_avail_o;
clocking drv_clk @(posedge clk); //clocking block for single clock, if you have more than clock
output exp_addr_i; // need to separate for each clock area
output exp_d_i;
output exp_ceb_i;
output exp_rwb_i;
input exp_avail_o;
endclocking
clocking imon_clk @(posedge clk); //clocking block for signals sync up for same clock
input exp_addr_i;
input exp_d_i;
input exp_ceb_i;
input exp_rwb_i;
endclocking
clocking omon_clk @(posedge clk);
input exp_addr_i;
input exp_ceb_i;
input exp_rwb_i;
input exp_avail_o;
input exp_q_o;
input exp_dv_o;
endclocking
