使用modelsim进行仿真时，在延一拍处理过程中，出现数据采集不到，pix_data_1d的数据采集不到，代码如下：reg fram_h1d;
reg fram_h2d;
reg fram_h3d;
reg fram_h4d;
reg fram_h5d;
reg fram_hpose_2d;
reg fram_hnege_1d;
reg fram_hnege_2d;
reg fram_hnege_3d;

reg [ 9:0] pix_data_1d;
reg [ 9:0] pix_data_2d;
reg [ 9:0] pix_data_3d;
reg [ 9:0] pix_data_4d;
always@( posedge CLK or negedge RST_N )
begin
IF( RST_N == 1'b0 )
      begin
         fram_h1d    <= 1'b0 ;
         fram_h2d    <= 1'b0 ;
         fram_h3d    <= 1'b0 ;
         fram_h4d    <= 1'b0 ;
         fram_h5d    <= 1'b0 ;
         fram_v1d    <= 1'b0 ;
         fram_v2d    <= 1'b0 ;
         fram_v3d    <= 1'b0 ;
         fram_v4d    <= 1'b0 ;
         fram_v5d    <= 1'b0 ;
         fram_v6d    <= 1'b0 ;
         fram_hpose_2d <= 1'b0 ;
         fram_hnege_1d <= 1'b0 ;
         fram_hnege_2d <= 1'b0 ;
         fram_hnege_3d <= 1'b0 ;
      end
else
      begin
         fram_h1d    <= FRAME_HI ;
         fram_h2d    <= fram_h1d ;
         fram_h3d    <= fram_h2d ;
         fram_h4d    <= fram_h3d ;
         fram_h5d    <= fram_h4d ;
         fram_v1d    <= FRAME_VI ;
         fram_v2d    <= fram_v1d ;
         fram_v3d    <= fram_v2d ;
         fram_v4d    <= fram_v3d ;
         fram_v5d    <= fram_v4d ;
         fram_v6d    <= fram_v5d ;
         fram_hnege_2d <= fram_hnege_1d ;
         fram_hnege_3d <= fram_hnege_2d ;
         fram_hpose_2d <= fram_h1d && ( !fram_h2d ) ;
         fram_hnege_1d <= fram_h1d && ( !FRAME_HI ) ;
      end
end

pix_data_1d的数据采集不到可能没调好吧
