使用Matlab HDL coder 产生的IP透过Vivado无法生成Bitstream

[ 已编辑 ]

 

请问一下各位,我使用了Matlab HDL coder生成了一个IP,却无法在Vivado中生成Bitstream

以下为我的Matlab code及使用的精度

下图为生成的code以及使用的port

下图是我的Block Diagram 使用的板子为Zedboard,然后使用Designer Assistance进行连接

到了生成Bitstream的时候出现了下图的错误码

由上而下分别是

  • [DRC DSPS-1] Invalid PCIN Connection for OPMODE value: DSP48E1 instance VMBD_i/dotproduct_fixpt_ipcore_0/U0/u_dotproduct_fixpt_ipcore_dut_inst/u_dotproduct_fixpt/dot2__11 has OPMODE[5:4] set to 01 which uses the input of the PCIN bus for its computation, however the PCIN input is not properly connected to another DSP48E1 Block. Please either correct the connectivity or OPMODE value to allow for proper implementation.
  • [DRC DSPS-1] Invalid PCIN Connection for OPMODE value: DSP48E1 instance VMBD_i/dotproduct_fixpt_ipcore_0/U0/u_dotproduct_fixpt_ipcore_dut_inst/u_dotproduct_fixpt/dot2__4 has OPMODE[5:4] set to 01 which uses the input of the PCIN bus for its computation, however the PCIN input is not properly connected to another DSP48E1 Block. Please either correct the connectivity or OPMODE value to allow for proper implementation.
  • [DRC PDRC-154] DSP48 OPMODE PCIN requirement: Invalid there is is no driving cell configuration: Cell VMBD_i/dotproduct_fixpt_ipcore_0/U0/u_dotproduct_fixpt_ipcore_dut_inst/u_dotproduct_fixpt/dot2__11 has OPMODE[6:0] set to x01xxxx (use PCIN bus), but design to supply the connections to a PCOUT bus. The OPMODE or DSP48E1 should be changed to fix this invalid condition. If a '0' input is needed, the ZMUX select should be changed so the OPMODE would be 000xxxx.

    请问各位我该如何调整设定才能成功生成Bitstream?
