Steps to create a UVM environment 1. Create a custom class inherited from uvm_env , register with factory, and call new 2. Declare and build verification components 3. Connect verification components together Environment Reuse Example What is UVM environment ? A UVM environment contains multiple,...
Full UVM Environment for CCI-400 This paper will focus on building a Universal Verification Methodology (UVM) based verification environment that will help you verify an ACE-based interconnect. We will use ARM CoreLink™ CCI-400 as the design under test (DUT) in order to demonstrate all...
UVM allows for block-level up to system-level verification. Ensures interoperability among multiple verification components. You can buy preexisting code like IP and intellectual property, which is already UVM compatible. This makes it much easier to integrate into your environment. ...
base test的build_phase()创建了ubus_example_env。任何从ubus_example_base_test派生的Testcase都会继承 ubus_example_base_test 中的所有定义,这意味着如果派生的Testcase调 用 super.build_phase() , 也会将构建top-levelenvironment。 从Base Test基类创建测试用例 测试用例编写者可以从Base Test派生出使用相同验...
此参数默认情况下设置为UVM_ACTIVE,在environment类中创建agents时,可以使用**set_config_int()**进行更改。然后,agent的build phase阶段应具有以下代码以选择性地构建driver和sequencer。 function void build_phase(uvm_phase phase); if(m_cfg.active == UVM_ACTIVE) begin//create driver, sequencerend endfunct...

关于代理器和相应BFM的更多内容可参考https://verificationacademy.com/patterns-library/implementation-patterns/environment-patterns/bfm-proxy-pair-pattern 接下来我们研究一下APB agent是如何组成、配置、构建和连接的。APB agent的pin接口apb_if编写在apb_if.sv文件中。命名为apb_monitor_bfm的monitor BFM接口有一...
In the above example, we have used the open-source Verilog design from Github. To demonstrate that this technique also works with VHDL designs, we have translated the design into VHDL. As the VHDL design is a different DUT, a seperate top level testbench is also required. Note that the ...
