描述

When implementing a design with a Tandem enabled UltraScale FPGA Gen3 Integrated Block for the PCI Express core and MIG or debug IPs, the tool gives the following error during implementation:

[DRC 23-20] Rule violation (HDTC-12) CONFIG cells must be in stage one - Configuration cell 'dbg_hub/inst/N_EXT_BSCAN.bscan_inst/SERIES7_BSCAN.bscan_inst' is not marked as a stage 1 cell. This cell must be added to stage 1 or removed from your design. You may also need to add additional driving logic to stage 1 as dictated by the desired design behavior. To add this cell to stage 1, please do the following: 
        set_property HD.TANDEM 1 [get_cells dbg_hub/inst/N_EXT_BSCAN.bscan_inst/SERIES7_BSCAN.bscan_inst]
        add_cells_to_pblock [get_pblocks -of_object [get_sites CONFIG_SITE_X0Y0]] [get_cells dbg_hub/inst/N_EXT_BSCAN.bscan_inst/SERIES7_BSCAN.bscan_inst]

When implementing a design with a Tandem enabled UltraScale+ Devices Integrated Block for PCI Express core and MIG or debug IPs, the tool gives the following error during implementation:

[DRC HDTC-12] CONFIG cells must be in stage one: Configuration cell 'dbg_hub/inst/BSCANID.u_xsdbm_id/SWITCH_N_EXT_BSCAN.bscan_inst/SERIES7_BSCAN.bscan_inst' is not marked as a stage 1 cell. This cell must be added to stage 1 or removed from your design. You may also need to add additional driving logic to stage 1 as dictated by the desired design behavior. To add this cell to stage 1, please do the following:
    set_property HD.TANDEM_IP_PBLOCK Stage1_Main [get_cells dbg_hub/inst/BSCANID.u_xsdbm_id/SWITCH_N_EXT_BSCAN.bscan_inst/SERIES7_BSCAN.bscan_inst]

解决方案

To resolve this issue, create a Tcl file, add the Tcl file in the tcl.pre* field of the Place Design section in the Implementation settings and then either add the Option 1 OR Option 2 content below in the Tcl File.

Option 1 (UltraScale): The generic approach

Option 1 (UltraScale+): The generic approach

OR

Option 2 (UltraScale) You can use the constraint that is directly listed in the error message

Option 2 (UltraScale+) You can use the constraint that is directly listed in the error message

Note: In incremental flow, run the commands before RCI (read_checkpoint -incremental)
