Prior to AMD Vivado™
2021.1 IDF+DFX DRCs are
disabled by default.
To enable the IDF DRCs, run the following command from the Tcl
console:
set_param hd.enableIDFDRC 1This parameter information is not stored in the database and must be
re-enabled for every Vivado session. The
parameter is most easily set in vivado_init.tcl
which automatically sets the parameter for each of the Vivado sessions. From Vivado
2021.1 onwards, to enable the IDF DRCs there is no need to set hd.enableIDFDRC param. IDF DRCs are enabled
automatically by the tool when the tool detects that HD.ISOLATED property is set to true.
