Some time ago, I reported a FPGA compile server error with LV8.5 under Windows XP. http://forums.ni.com/ni/board/message?board.id=280&message.id=3050&query.id=44591
The compiling stopped with following error message:
Mapping design into LUTs... ERROR:MapLib:661 - LUT2 symbol "mytop/n_3491/n_3486/n_3475/n_3467/HiCompare/BU2/U0/gen_structure_logic.gen_n onpipelined.a_lt_ge_gt_le_b.i_gen_carry_chain_comp/sel_0_mux00001" (output signal=mytop/n_3491/n_3486/n_3475/n_3467/HiCompare/BU2/U0/gen_structure_logic .gen_nonpipelined.a_lt_ge_gt_le_b.i_gen_carry_chain_comp/sel<0> has input signal "mytop/n_3491/n_3486/n_3475/n_3467/HiCompare/b<15>" which will be trimmed. See the trim report for details about why the input signal will become undriven.
There was a reply to change the regional settings to "english" to solve the problem. This didn't worked. I tried now to compile the VI with another computer with german Windows Vista Business Edition and the same error occured.
Can anyone tell me which source may cause that error?
