6.15 Configuration and parameters
This section summarizes the differences between GIC-600 and GIC-600AE.
Added configurations to GIC-600
•
The fusa_comp_dup parameter can add one more gate into the comparator paths. For more
information, see 6.6.1 Comparators on page 218.
•
The fusa_axis_int_busprot_type parameter indicates the bus protection to be deployed on
the AXI4-Stream interfaces between the GIC-600AE blocks.
•
The fusa_spi_prot parameter indicates whether parity _chk signal bit protection is deployed to
SPI interrupt inputs.
•
The fusa_ppi_prot parameter indicates whether parity _chk signal bit protection is deployed to
PPI interrupt inputs.
•
The fusa_disable_pqchan_prot parameter can disable P-Channel and Q-Channel Safety
Mechanisms.
For more information, see 6.10.4 Disabling P-Channel and Q-Channel Safety Mechanisms on
page 238.
For more information about these parameters, see the Configuration options chapter of the Arm

Reduced configurations from GIC-600
•
The GIC-600AE does not support the option to have RAM macros (compiled memories)
without ECC.
•
The GIC-600AE does not render logic on external interfaces, including the external GIC-
Stream-AXI4-Stream interface.
•
The GIC-600AE can render the msi_64 module, but it is not protected. This block is an
optimization and is not required for correct operation of the GIC-600AE.
•
On GIC-600AE, the supported range of values for ppi_count is 1-32.
•
On GIC-600AE, the supported range of values for its_count is 1-8.
For more information about these considerations, see the Configuration options chapter of the Arm
