         编译、综合通过，但是在implement Design的的map上报错，请问怎样解决如下问题：
MapLib:979 - LUT4 symbol "XLXI_11/BU2/U0/grf.rf/gl0.wr/gwas.wsts/ram_almost_full_i_mux000042" (output signal=XLXI_11/BU2/U0/grf.rf/gl0.wr/gwas.wsts/ram_almost_full_i_mux000042) has input signal "XLXI_11/BU2/U0/grf.rf/gcx.clkx/rd_pntr_bin<1>" which will be trimmed. See Section 5 of the Map Report File for details about why the input signal will become undriven.

MapLib:979 - LUT3 symbol "XLXI_35/num_not00011" (output signal=XLXI_35/num_not0001) has input signal "XLXI_35/tx_en" which will be trimmed. See Section 5 of the Map Report File for details about why the input signal will become undriven.

MapLib:978 - LUT4 symbol "XLXI_11/BU2/U0/grf.rf/gl0.wr/gwas.wsts/c2/dout_i103" (output signal=XLXI_11/BU2/U0/grf.rf/gl0.wr/gwas.wsts/c2/dout_i103) has an equation that uses input pin I2, which no longer has a connected signal. Please ensure that all the pins used in the equation for this LUT have signals that are not trimmed (see Section 5 of the Map Report File for details on which signals were trimmed).

我是把时钟分配改了就可以，可能主要是时钟约束的问题吧，请大家拍砖

不是那个问题造成的。
