基于Cadence Palladium Z1的图形芯片功能验证平台

Functional Verification Platform of Graphics Chip Based on Cadence Palladium Z1

在集成电路设计过程中,验证的工作量占到所有工作量的70%。大型的计算机图形处理芯片的功能验证,测试周期很长,覆盖率要求高,对于验证工程师提出了比较高的挑战。基于Cadence最新一代企业级CPU并行计算仿真器(Palladium Z1),提出了一种各平台通用,高效,流程简洁并且覆盖率较高的测试平台。该方法涵盖了测试指令集设计,GPU测试的原理分析。并给出了在Cadence Z1平台上,测试向量在测试平台上的运行过程和回归测试的结果。

It is very important for RFID to measure a set of more complete test item before it reach the hand of end user. There are a series of international trade standard for RFID test, in which set up serious prescribe for RFID spec and performance including its characters and application ranges. In this text, Besides it study RFID from application technology, development, and working principle, the test project for a type of RFID, which has been put into product, was made about RF character measurement, logical function measurement, memory measure, and simulation measurement under special condition.
