constrain the tranceivers of SRIO

i use spartan6slx25T, which have only one GTPA1_DUAL_X0Y0, i can implement one x1 mode(lane 0 in GTPA1_DUAL_X0Y0) and it work well, but i need to use two x1 mode,and i try to instance another SRIO IP(lane 1 in GTPA1_DUAL_X0Y0), but the constraints is error. so can u tell me how to constraint lane 1 in GTPA1_DUAL_X0Y0

 

INST "u_camera_process/inst_test_srio_top/rio_de_wrapper/phy_wrapper_inst/srio_gt_wrapper/gtp_wrapper_i/tile0_gtp_wrapper_i/gtpa1_dual_i" LOC = "GTPA1_DUAL_X0Y0";# lane0
INST "u_camera_process/inst_test_srio_top_1/rio_de_wrapper/phy_wrapper_inst/srio_gt_wrapper/gtp_wrapper_i/tile0_gtp_wrapper_i/gtpa1_dual_i" LOC = "GTPA1_DUAL_X0Y0";# lane1

Re: constrain the tranceivers of SRIO

What is the exact error you are getting?  Usually it's possible to use two lanes, but if each IP is instantiating some shared portion of the GTP_DUAL, then you can get conflicts.

Re: constrain the tranceivers of SRIO

here is the error ERROR:Pack:2811 - Directed packing was unable to obey the user design constraints (LOC=GTPA1_DUAL_X0Y0) which requires the combination of the symbols listed below to be packed into a single GTPA1_DUAL component. The directed pack was not possible because: The target component type can only contain one fragment. The symbols involved are: GTPA1_DUAL symbol "u_camera_process/inst_test_srio_top_1/rio_de_wrapper/phy_wrapper_inst/srio_g t_wrapper/gtp_wrapper_i/tile0_gtp_wrapper_i/gtpa1_dual_i" (Output Signal = NULL) GTPA1_DUAL symbol "u_camera_process/inst_test_srio_top/rio_de_wrapper/phy_wrapper_inst/srio_gt_ wrapper/gtp_wrapper_i/tile0_gtp_wrapper_i/gtpa1_dual_i" (Output Signal = NULL) Mapping completed. See MAP report file "top_map.mrp" for details. Problem encountered during the packing phase.
