Delivering product quality within tight schedules requires maximizing verification effectiveness to speed time to coverage closure.
Generative AI, or GenAI, is a subset of artificial intelligence technology that creates something new from a dataset of previous examples. It typically relies on complex algorithms and neural networks to simulate human creativity and produce new output. In chip design, GenAI can help explore ...
UVM支持覆盖驱动的验证(CDV, Coverage-Driven Verification),即可以按照特定规则(如随机化)生成Sequence,不断提高验证的覆盖率(指设计中各个部分被调用以进行验证各个规范内定义的行为)。 图9 一个简单的UVM 框架示例 更进一步的UVM整体框架介绍在博客园用户没落骑士的这篇文章中有稍微详细一点的介绍,UVM内部各个模块...
Code coverage is not a panacea. Coverage generally follows an 80-20 rule. Increasing coverage values becomes difficult with new tests delivering less and less incrementally. If you follow defensive programming principles where failure conditions are often checked at many levels in your software, some ...
ourVerification IPuses native System/Verilog UVM architecture for acceleration of testbench development and has a built-in verification plan, sequences, and functional coverage. Another example of our experience with the new features is ourCXL IP, which also implements FLIT mode. In the end, thoug...
验证证明设计的正确性和逻辑功能,在使用硬件描述语言(VHDL/Verilog)对RTL设计进行编码后,即可完成该过程。它是用高级语言编写testbech来完成的。这仅在芯片实际制造之前执行一次,在设计中,通过system verilog进行验证,例如UVM。验证本身是一个单独的话题,这里不深入讨论。
