Why don’t the new Nios® V/c processor features appear after upgrading the Nios® V/c Processor IP to Quartus® Prime Pro version 26.3?

Description

In Quartus® Prime Pro Edition 26.3, the Nios® V/c processor IP is renamed from intel_niosv_c to niosv_c across all FPGA device families. Performing IP Upgrade from earlier Quartus® Prime project will retain the legacy intel_niosv_c in your project.

For your information,

• This legacy intel_niosv_c IP remains at last updated back in Quartus® Prime Pro Edition 26.1.1.
• While new Nios® V/c processor IP feature are introduced into niosv_c IP starting from Quartus® Prime Pro Edition 26.3.

In another words, auto-upgrade of intel_niosv_c to niosv_c in not supported by IP Upgrade.

Thus, you may find those new Nios® V/c processor features (in niosv_c) is missing in intel_niosv_c.

Resolution

If new Nios® V/c processor features (such as Debug option) is required, re-instantiate the Nios® V/c processor in Quartus® Prime Pro version 26.3.
