我目前正在使用16902B逻辑分析仪,并一直在尝试使用模式生成器。
我正在进行的设计等待分析仪触发。 序列等待臂进入并且它们递增地址(总共32个引脚)。 我的问题是我无法找到如何从当前位置增加地址引脚,任何人都知道如何做到这一点? 以上来自于谷歌翻译 以下为原文 I am currently using the 16902B Logic Analyzer and have been attempting to use the Pattern Generator. The design I am working on waits for a trigger from the analyzer. The sequence waits for the ARM in and them increments the address (32 pins total). My issue is I have not been able to find how to increment the address pins from there current locations, anyone know how to do this? |

我不太确定你在问什么...模式生成器上没有“地址”引脚。
如果您有一个名为“地址”的已定义字段,那么这是一个不同的问题。 请发布一些有关您尝试过的内容以及您要做的事情的更多信息...... Al 以上来自于谷歌翻译 以下为原文 I'm not quite sure what you are asking... There are no "address" pins on the Pattern Generator. If you have a defined field called "address", then that's a different question. Please post a little more information about what you have tried and what you are trying to do... Al |

nvywyerwer 发表于 2018-11-1 06:33 我已经将来自模式发生器的pod信号定义为“地址”,其中32个是完整的,序列位于等待来自分析器的arm进入,当它读取触发器时我希望它增加我定义为地址的引脚。 例如:地址定义引脚的当前读数是xFFF0 BB10,当它看到触发时它将增加到xFFF0 BB14。 下一个周期将从xFFF0 BB14增加到xFFF0 BB18,以便看到下一个触发器等。这当然会使模式发生器重复运行。 以上来自于谷歌翻译 以下为原文 I have defined pod signals from the pattern generator as "address", 32 of them total, the sequence sits and waits for arm in from the analyzer, when it reads the trigger I want it to increment the pins I defined as address. eg: The current reading of the address defined pins are xFFF0 BB10 and when it sees the trigger it will increment to xFFF0 BB14. The next cycle will increment from xFFF0 BB14 to xFFF0 BB18 for next trigger seen, etc. This of course has the pattern generator running repeatedly. |

victorlekwk 发表于 2018-11-1 06:47 手臂和/或扳机不能以这种方式使用。 - “等待ARM in”命令只能在序列中使用一次,并且不能在循环内使用。 - 分析器只会为每次“运行”断言一次ARM。 - 由于它是一个相关的信息,每次运行分析仪只有一个“触发器”。 如果您的设备可以告诉模式生成器是时候转到下一个值,您可以使用“等待外部事件”来完成您想要的任务。 如果没有很多编程(甚至可能不是那样),就没有办法做以下事情: - 用分析器查找事件 - 用生成器做一些事情 - 用分析器寻找一些东西 - 用生成器做点什么。 等...... Al 以上来自于谷歌翻译 以下为原文 The arm and/or trigger can't be used that way. - The "wait for ARM in" command can only be used once in a sequence, and it can't be used inside a loop. - The analyzer will only assert ARM out once for each "run". - Since it's a related piece of information, there is only one 'trigger' per run of the analyzer. You might be able to use "Wait for External Event" to accomplish what you want, if your device can tell the pattern generator that it's time to go to the next value. There is no way, without a lot of programming (and maybe not even then) to do something like: - Look for an event with the analyzer - Do something with the generator - Look for something with the analyzer - Do something with the generator. etc......

nvywyerwer 发表于 2018-11-1 06:53 有一种感觉,将不得不调查等待外部,看看是否会有效。 此外,很高兴您提到了分析仪触发器。 我的印象是,一旦达到运行并且填充部分,分析器就会循环回到步骤1。 我可以运行生成器用于运行代表,并且分析器的单次运行似乎会触发发生器很多。 以上来自于谷歌翻译 以下为原文 Had a feeling about that, will have to investigate wait for external and see if that will work. Also, glad you mentioned the analyzer trigger. I was under the impression that the analyzer looped back to step 1 once it reaches the run and fill portion for however long the run goes for. I can run the generator for run rep and a single run of the analyzer seems to trigger the generator a lot. |
