DFT compiler set_autofix

Hi,

I'm setting certain elements to NOT be scanned.
But looks like set_dft_configuration overrides this.

1) set_dft_configuration (acts like autofix)

Need someone to confirm.

set_scan_element false { module1 module2 }

set_dft_configuration -fix clock_enable
set_dft_configuration -fix reset

2) locally autofix

I tried to locally apply the autofix but DFT compiler complains about

set_autofix_element [get_cells i_abc/i_xyz/*reg*] -type clock -method mux -control_signal Testmode -test_data scanclk
Error: TestData signal type not specified for the port scanclk (TESTXG-11)
Discarded Autofix element specifications.

and tried to make scanclk as Testdata

set_dft_signal -view spec -test_mode all -type TestData -port scanlk
Error: Multiple signal types cannot be specified for hookup port 'scanclk'. (UIT-663)
Discarded dft signal specification

Anyone have good working example of set_autofix_element with the set_dft_signals ?

Thanks
