Vivado - routing errors with System Management Wizard due to SYSMONE1 used

Description

When using the IPI version of the System Management Wizard on a Kintex UltraScale device, several of the SYSMONE1 connections are unable to route:

CRITICAL WARNING: [Route 35-54] Net: Top_i/system_management_wiz_0/inst/i2c_sda_iobuf/O is not completely routed.
Resolution: Run report_route_status for more information.
CRITICAL WARNING: [Route 35-54] Net: Top_i/system_management_wiz_0/inst/i2c_sda_ts is not completely routed.
Resolution: Run report_route_status for more information.
CRITICAL WARNING: [Route 35-54] Net: Top_i/system_management_wiz_0/inst/i2c_sclk_iobuf/O is not completely routed.
Resolution: Run report_route_status for more information.
CRITICAL WARNING: [Route 35-54] Net: Top_i/system_management_wiz_0/inst/i2c_sclk_ts is not completely routed.
Resolution: Run report_route_status for more information.

Why is this happening?

Solution

This is due to the incorrect SYSMONE1 site being chosen.

On this specific Kintex UltraScale device, there are two SYSMONE1 sites.

One is bonded and the other un-bonded.

The un-bonded site is being chosen which causes the routing issue.

This is planned to be fixed in a future release of Vivado.

To work around this, constraints such as the following can be used to specify the correct SYSMONE1 site:

set_property BEL SYSMONE1 [get_cells Top_i/system_management_wiz_0/inst/inst_sysmon]
set_property LOC SYSMONE1_X0Y0 [get_cells Top_i/system_management_wiz_0/inst/inst_sysmon]
