Warning: Local Clock and Reset Nets

The following clocks or resets are driven by fabric-generated or local nets and are not single event transient (SET) mitigated:

From From Location I/O Bank To To Location Net Name Fanout
1 RTG4_uPROM_0/COREUPROMIF_APB_C0_0/COREUPROMIF_APB_C0_0/UCLK_sync_reset:Q (1432, 10) - RTG4_uPROM_0/COREUPROMIF_APB_C0_0/COREUPROMIF_APB_C0_0/UCLK_sync_reset_RNILE96:An GBR[7] RTG4_uPROM_0/COREUPROMIF_APB_C0_0/COREUPROMIF_APB_C0_0/UCLK_sync_reset_0 1

Microchip recommends the use of dedicated global clocks with built-in single event transient (SET) mitigation.

The following local resets are not driven by three separate logic cones and are not radiation protected:

From From Location To Net Name Fanout
1 SYSRESET_0:POWER_ON_RESET_N (1490, 2) RGRESET SYSRESET_0_POWER_ON_RESET_N 5

For radiation protection, Microchip recommends that each of the three inputs of every RGRESET be driven by three separate logic cones replicating the paths from the source registers.
