Device Family: Intel® Stratix® 10 GX, Intel® Stratix® 10 SX

Intel Software: Quartus Prime Pro

Area: Component


Version Found: v19.4
Bug ID: 1507974885

Why the measured current strength in bank 3C of Intel® Stratix® 10 GX 400 and SX 400 devices is unable to meet the set level in Intel® Quartus® Prime Pro?

Description

Although the Intel® Stratix® 10 General Purpose I/O User Guide shows the supported current strength settings in bank 3C of Intel® Stratix® 10 GX 400 and SX 400 devices are 16mA, 12mA, 8mA and 4mA, which are allowed in Intel® Quartus® Prime Pro Edition software version 20.2 and earlier. However, please expect the actual current strength from output I/O buffer will follow the table below:

Workaround/Fix

This problem is scheduled to be fixed in a future release of the Intel® Quartus® Prime Pro Edition software and associated documentation to reflect the actual current strength.
Users are required to recompile the design with fixed Intel® Quartus® Prime Pro release.
