Excel-compatible Tabulation Option for Constraint Files

Created: February 25, 2016 | Updated: December 14, 2017 | Applies to version: 16.0

The feature documented here is no longer part of the software beyond version 16.0. Click to return to: Altium Designer Documentation for version 25

FPGA constraint files can now be saved in a tabulated format which is compatible with Excel spreadsheets.

To save a constraint file from your FPGA project, simply select File » Save Copy As. From the Save Copy As file browser, click Save as type and select Tab-Delimited Constraint files (*.Constraint). The constraint file still be exported in a TXT format which can be opened in a word processor, however, the tab-delimited file can also be viewed as a spreadsheet with Microsoft Office's Excel, making it easy to view and manage pin assignments.

It is recommended to select Save Copy As instead of Save As because a saved copy will remain in the Tab-Delimited format even after you save the original file later. However, when you Save As, Altium Designer will continue working with the same file (though under a different name) and the tabulated formatting will be lost after the next Save command, as the software automatically converts constraint files to their default format.

Selecting the Tab-Delimited Constraint files (*.Constraint) option from the Save Copy As file browser.

The files are easily viewable in Excel.
