1. 测试平台
1.1 概述



1.2 练习
下列关于测试平台哪个是正确的?
解析:ABC
D选项,测试也是需要时钟和复位信号的。
2. 硬件设计描述
以MCDF(multi-channel data formatter),多通道数据整形器为例说明。
2.1 端口信号说明




2.2 端口时序说明
2.2.1 通道从端接口时序

2.2.2 控制寄存器接口时序

2.2.3 整形器接口时序

2.3 MCDF寄存器描述


2.4 练习

答案:ABCD

答案:CD
A,错误,确定channel之后,他要发送的长度就已经定了,不可改变;B,req和grant至少相差一个时钟周期,不能在同一个时钟周期同时拉高。

答案:CD
解析:由题可知,寄存器地址0x10 为只读寄存器,所以是不可以写入的,所以读出的数值可能为FIFO的深度,即0x0000~0x80.

答案:ABCD
3. 激励发生器
3.1 概述



3.2 激励发生器组件结构框图

3.3 激励发生器的实现


3.4 练习

答案:CD
解析:A错误,stimulator只是向DUT的外部接口发送激励,而不是内部信号;B错误,是分为initiator和responder。

答案:ABD
解析:C错误,arbiter不是,因为它没有外部端口信号。
4. 监测器
4.1 概述

4.2 监测器组件结构框图
4.2.1 方案一

方案一就是将检测器做成一个整体,实现对所有端口进行监测。
4.2.2 方案二

方案二是针对每个端口都进行监测。
4.2.3 方案比较

4.3 内部信号监测原则

4.4 练习

答案:ABC
解析:D错误,比较不是monitor干的活,那是checker干的。
5. 比较器
5.1 概述

5.2 功能

5.3 实现方式


5.4 比较器组件结构框图





5.5 实现原则

5.6 练习

答案:ABCD

答案:ABC
分析:D错误,集中搁置反而会简单。
