Vivado¶
Vivado has a single warning format, but two different type of warnings: critical warnings and non critical warnings. Some warning messages can also span multiple lines.
Critical Warnings¶
Warnings with IDs are identified with the Warning keyword and the ID between colons. The message is after the second colon.
<warning keyword>: [<ID>] <message>
where:
| Item | Regular Expression Match |
|---|---|
| warning keyword | ^CRITICAL WARNING |
| ID | \W+sW+ |
| message | .*$ |
Non Critical Warnings¶
Non critical warnings are identical to critical warnings except the keyword.
<warning keyword>: [<ID>] <message>
where:
| Item | Regular Expression Match |
|---|---|
| warning keyword | ^WARNING |
| ID | \W+sW+ |
| message | .*$ |
Multiline Warnings¶
Multiline warnings can span any number of lines. They are identified with at least on space at the beginning of the line for each line after the initial warning line.
<warning keyword>: [<ID>] <message1> <warning continuation><message2> <warning continuation><message3>
where:
| Item | Regular Expression Match |
|---|---|
| warning keyword | ^[WARNING|CRITICAL WARNING] |
| ID | \W+sW+ |
| message1 | .*$ |
| warning continuation | ^s+ |
| message2 | .*$ |
| message3 | .*$ |
Extracting Warnings¶
Extraction of warnings from the logfile will follow this process:
- Search for lines starting with WARNING or CRITICAL WARNING
- Extract ID and message
- Check successive lines for line beginning with spaces
- append line to existing message
