Description

When a write_chipscope_cdc command is issued on my design, the following warning is received:

WARNING: [Vivado 12-3101] Could not find an ICON 1.0 controller in the design so so no debug cores will be exported to the CDC file.

Solution

The write_chipscope_cdc command is only supported by V1.0 Icon cores. 

For Vivado V2.0 Logic Debug Cores, you can use the following tcl command to obtain a list of nets with the "mark_debug" property:

get_nets * -filter {mark_debug == TRUE}
