failed to generate .saif using "irun" command -> "Unrecognized system task or function"

Hi,

I failed to generate .saif using "irun" command

All my function i tried to use: $read_rtl_saif, $set_toggle_region, $toggle_start, $toggle_stop, $toggle_report are being warned as "Unrecognized system task or function" by NCSIm.

Anyone may suggest why is this happening?

Thanks.
