Vivado debug異常現象

前言

bit文件和ltx文件的信號位寬不匹配問題。用了dont_touch等屬性沒用。。。

 

WARNING: [Labtools 27-1972] Mismatch between the design programmed into the device xc7z035 (JTAG device index = 1) and the probes file(s) xxxx/dev/project_1.runs/impl_1/xxx.ltx.
The core at location uuid_23E7D65A79BC59F7BC47406C1714DFAE has different widths for ILA input port 0. Port width in the device core is 38, but port width in the probes file is 37.
Resolution:
1. Reprogram device with the correct programming file and associated probes file(s) OR
2. Goto device properties and associate the correct probes file(s) with the programming file already programmed in the device.

 

流程

生成bit文件后，直接修改ltx文件內不匹配的信號。

路徑說明：

 bit file中是38bit位寬的。所以對ltx文件中相應的信號增加1bit位寬即可。

檢查下勞動成果，可以看到可以正常debug了。
