How to prevent DFT from changing names?

DFT changes names

After synthesis in DC I have flops in register with names FRAME_COUNT_reg[number] , but after insert_dft it changes names on FRAME_COUNT_reg_number_, how to prevent this name changing. Is there possibility to write netlist in FRAME_COUNT_reg[number] format?

Re: DFT changes names

hi,

use the following command before using insert_dft command. This command preserves the design name.

set_dft_insertion_configuration -preserve_design_name
insert_dft

Re: DFT changes names

Are you using the command

change_names -rules verilog ..... if yes then it is causing the flattening of the bus.

You can set your own rule of not changing the naming style....

look for the following commands

change_names(2)
define_name_rules(2)
report_names(2)
