From an error to a useful next step
A report connects a log message to its likely cause and a check you can run locally.
- Log evidence
[Synth 8-439] module 'uart_rx' not found- Likely cause
- The module is missing from the synthesis sources.
- Next check
- Check the module name and source files, then rerun synthesis.
Three steps to a clearer diagnosis
- Add a log
Paste text or upload a log file. Remove sensitive information first.
- Review the report
Read the evidence, suggested fixes and limitations.
- Check locally
Test the change in your toolchain. Save the report for reference.
