Critical Warning (21688): The total mutual inductance (Lm) of 1.0 V I/O < pin location > with surrounding 1.0 V I/O pins is < total mutual inductance value > nH. This is not allowed. The total mutual inductance must be less than or equal to < value

Environment

Bug ID: 1509230986, 1508800992

Quartus Edition

Intel® Quartus® Prime Standard Edition

Version Found: 21.1

BUILT IN - ARTICLE INTRO SECOND COMPONENT

Critical Issue

Description

You may receive this error when you place pins surrounding 1.0 V I/O standard pins within the same bank despite meeting the total mutual inductance requirement based on mutual coupling spreadsheet for Intel® MAX® 10 FPGA device. This is a known issue due to the outdated database for both the Intel® Quartus® and the spreadsheet.

Resolution

This problem is scheduled to be fixed in a future release of the Intel® Quartus® Prime Edition software.
