能够直接在实现中选择多路复用器的信号吗

大家好,
我尝试学习Planahead,我目前正在研究位于Planahead教程项目文件夹中的bft_core项目。
当我检查RTL原理图时,我可以看到一些多路复用器,我可以很容易地发现它们的选择信号。
我想直接从Planahead生成的实现文件中找到相同的信号,而不是先从RTL中找到它们。
这是可能的,如果是的话怎么样?
在实现级别中,所有互斥锁都被LUT替换,因此很难找到选择信号。
非常感谢你的帮助!

Hello everyone,
I try to learn Planahead and I am currently working on the bft_core project which is in the tutorial projects folder of Planahead. When I examine the RTL schematic, I can see some multiplexers and I can easily spot their select signals. I want to find the same signals right from the implementation files that are generated by Planahead without finding them from the RTL first. Is that possible and if yes how? In implementation level all mutexes are replaced by LUTs so it's difficult to find the select signals.
Thank you so much for your help!

嗨,您是否尝试打开实施的设计并搜索信号?问候,Achutha

Hi,
Did you try opening the implemented design and search for the signal ?

感谢您的回复。
也许我不够清楚。
我会尝试解释我的目标。
我想找到所有激活和控制电路中所有路径的信号。
我无法从.edf和.twr文件中做到这一点。
所以,我认为最好“升级”到RTL级别并检查mutux的选择信号。
有没有办法从实现文件中找到路径的所有控制信号?

Thanks for your reply.
Maybe I wasn't clear enough. I will try to explain my goal. I want to find all signals that activate and control all the paths  in a circuit. I could'n do it from the .edf and .twr files. So, I thought that it might be better to go "up" to the RTL level and check the select signals of the mutuxes. Is there a way to find all control signals of paths right from implementation files?

嗨,异步控制信号的详细信息在XST综合报告的“异步控制信号信息”部分中列出。有关其他详细信息,您可以查看RTL或打开合成设计并跟踪控制信号.Regards,Achutha

Hi,

The details of Asynchronous control signals is listed in the XST synthesis report under the section "Asynchronous Control Signal Information.

For other details you may either have look at the RTL or open the synthesized design and trace the control signals.

非常感谢您的回复。
不幸的是,你提到的部分说“在这个设计中找不到异步控制信号”,所以我需要一些帮助。
在planahead的教程文件夹中,我在bft_core项目上工作。
当我打开RTL设计时,我看到很多多路复用器,我发现了6个不同的选择信号(wbDataForInputReg,loadState,reset,egressFifoEmpty,GND_6_o_demuxState_equal_37_o,GND_6_o_fifoselect [7] _equal_26_o)。
我想在实现设计中发现这些特定的选择信号(它们可能已重命名,因为所有多路复用器已被LUT替换,但我找不到匹配项)。
是否可以在“较低”级别跟踪这些信号?
我感谢您的帮助。

Thank you very much for your reply. Unfortunately, the section you mentioned says "No asynchronous control signals found in this design", so I need some more help. In the tutorial folder of planahead I work on bft_core project. When I open the RTL design, I see many multiplexers and I have found 6 distinct select signals (wbDataForInputReg, loadState, reset, egressFifoEmpty, GND_6_o_demuxState_equal_37_o, GND_6_o_fifoselect[7]_equal_26_o). I want to spot these specific select signals in the implementation design (they are probably renamed because all multiplexers have been replaced by LUTs but I can't find the matches).
Is it possible to follow those signals in the "lower" levels?
I appreciate your help.
