The VIO output probes can be set using the VIO Probes window of the VIO Dashboard window. Each output probe is viewed as a separate row in the table. The value of the VIO output probes are shown in the Value column of the table (see Interacting with VIO Core output Probes). The VIO core output values are updated whenever a new value is entered into the Value column. Clicking on the Value column causes a pull-down dialog to appear. Type the desired value into the Value text field and click OK.

You can also write out a new value to the VIO core using Tcl commands. For instance, if you wanted to write a binary value of "11111" to the VIO output probe called vio_slice5_fb_2 whose radix is already set to BINARY, run the following Tcl commands:

set_property OUTPUT_VALUE 11111 [get_hw_probes vio_slice5_fb_2]
commit_hw_vio [get_hw_probes {vio_slice5_fb_2}]
