Error 129001 Compiling HPS Component

description

When compiling an HPS design, you might see an error message similar to the following:

Error (129001): Input port DATAIN on atom "hps_qsys:u0|hps_qsys_hps_0:hps_0|hps_qsys_hps_0_hps_io:hps_io|hps_qsys_hps_0_hps_io_border:border|hps_sdram:hps_sdram_inst|hps_sdram_p0:p0|hps_sdram_p0_acv_hard_memphy:umemphy|hps_sdram_p0_acv_hard_io_pads:uio_pads|hps_sdram_p0_altdqdqs:dq_ddio[0].ubidir_dq_dqs|altdq_dqs2_acv_connect_to_hard_phy_cyclonev:altdq_dqs2_inst|extra_output_pad_gen[0].config_1", which is a cyclonev_io_config primitive, is not legally connected and/or configuredThis error might appear if you add the HPS component to your top-level system by adding the source .qsysfile to the Quartus II project.

workaround / fix

Use the following standard Qsys system generation flow:

1. In Qsys, generate the HPS component subsystem.

2. Add the resulting .qip file to the Quartus II project.

add the .qip file to .v dirtectory?

After i add it, still have the error hint? how to solve it?
