Using Quartus II (15.1) and QSys to generate "soc_system.qsys". It contains a hps_0 instance. When the Qsys HDL files is generated it generates "soc_system/synthesis/submodules/soc_system_hps_0_hps_io_border.sdc". It contains a long list of statements like
set_false_path -from * -to
set_false_path -from * -to Quartus finds this .sdc file and tries to run it, and fails:
Info (332104): Reading SDC File: 'soc_system/synthesis/submodules/soc_system_hps_0_hps_io_border.sdc'
Warning (332174): Ignored filter at soc_system_hps_0_hps_io_border.sdc(1): hps_io_hps_io_emac1_inst_TX_CLK could not be matched with a port

Info (332050): set_false_path -from * -to The reason is that the ports names in the .sdc does not match any top-level ports, and as such all ports on the HPS system fails to match and creates massive number of warnings in the output. Is there a way to suppress this? How is this intended to work?
