摘要
No C结构规模巨大,内部电路互连非常复杂,No C内部串扰严重影响了片上系统的信号完整性。基于改进HT模型提出一种串扰测试的方法,实验结果表明,在改进的HT模型来中,N根传输线传统串扰测试方法需要测试6N次,而此方法只需要18次,从而有效地减小了开销。基于改进的HT故障种类模型设计了一套基于改进HT模型的测试代码,根据测试代码利用Pspice仿真软件设计了一种测试代码电路,该测试电路是利用16位数据选择器和16进制计数器构成,并对测试电路进行仿真测试,测试结果表明该电路能够满足测试要求并且具有可移植的优点。
As the scale of No C is huge and the interconnection in No C is complex, the crosstalk of No C serious impact on the integrity of signal in No C system. A new test method based on HT model was proposed in this paper for improved HT model with N transmission lines, the test time tradition method is 6N, while the test time of method in paper is 18. The method in paper can largely reduce test times and the cost of resource. A test codes based on improved HT model was designed and a new test circuit for these codes was built in paper. A 16- bit data selector and a 16- bit counter were used to build this circuit. The simulation was done by Pspice and the result showed that the test circuit satisfied the test requirements and had the advantage of portable.
