### Using partitioned based DFT Flow

# Should report 'default' as current dft partition
current_dft_partition

# Define DFT partitions 
define_dft_partition P1 -instances {i_cpu_sys nova1}
define_dft_partition P2 -instances { nova0}


report_dft_partitions

## define_scan_chain 
define_scan_chain -scan_in SI_1 -scan_out SO_1 -create_port -partition P1

current_dft_partition P2
# following definition scope is limited to P2
define_scan_chain -scan_in SI_2 -scan_out SO_2 -create_port

# Resetting the partition definition to 'Default'
reset_dft_partition

# Following scan chains should be created corresponding to 'Default' partition, meaning any logic outside of already coverd partitions.
