7.3. Viewing ECO Compilation Reports

The Compiler generates a report showing the details of each ECO compilation that you run successfully. You can view the report contents in the ECO Changes report under Fitter in the Compilation Report.
Figure 138. Example of ECO Changes Report

Alternatively, you can view this data in the generated fit.eco file. The Compiler organizes the report output according to the category of ECO change, such as Placement Changes. The table specifies the "Changes in Previous ECO Runs" and "Changes in Current ECO Run".
