Description
Due to a bug in the Stratix V PCIe Hard IP core the rx_st_err signal is incorrectly assigned in the file "altpcie_sv_hip_ast_hwtcl.v".
Resolution
To workaround this issue open the file "altpcie_sv_hip_ast_hwtcl.v" then find and change the following line:
From:
assign rx_st_err = |rx_st_err_int[3:0];
To:
assign rx_st_err = rx_st_err_int[0];
This issue will be fixed in a future version of the Quartus® II software release.
