bidir_reg.v

这是用python语言写的一个数字广播的信号处理工具包。利用它

// Bidirectional registers

module bidir_reg
  ( inout wire [15:0] tristate,
    input wire [15:0] oe,
    input wire [15:0] reg_val );

   // This would be much cleaner if all the tools
   // supported "for generate"........

   assign 	 tristate[0] = oe[0] ? reg_val[0] : 1'bz;
   assign 	 tristate[1] = oe[1] ? reg_val[1] : 1'bz;
   assign 	 tristate[2] = oe[2] ? reg_val[2] : 1'bz;
   assign 	 tristate[3] = oe[3] ? reg_val[3] : 1'bz;
   assign 	 tristate[4] = oe[4] ? reg_val[4] : 1'bz;
   assign 	 tristate[5] = oe[5] ? reg_val[5] : 1'bz;
   assign 	 tristate[6] = oe[6] ? reg_val[6] : 1'bz;
   assign 	 tristate[7] = oe[7] ? reg_val[7] : 1'bz;
   assign 	 tristate[8] = oe[8] ? reg_val[8] : 1'bz;
