    datapath configuration tool bug report

    teddy.wolf

      I found the following infomation in  "Datapath Configuration Tool Cheat Sheet_001-86838.pdf" page 9 

         

      Compare block 0 can compare only D0 and a masked value from A0.

         

      but when you run the  software: Datapath Configuration Tool,

         

      you can find CFG13-12 CMP SELA has many choice, none of them are A0_D0. I think this is a software bug.

         

       

         

      please correct it.

          Hi Teddy,

             

           

             

          you have to read it complete:

             

          CMP SELB & CMP SEL A

             

          Configures   the   Comparison   B   and
          Comparison   A   Options   for   compare
          block >>>1<<<. The CMP SEL field of the RAM
          configuration  determines  if  the  A  or  B
          option is in effect for a given cycle. 
          Note:  Compare  block  0  can  compare
          only D0 and a masked value from A0.

             

           

             

          Regards,

            Hi,

               

            Thanks for your reply.

               

            I took for granted CMP SELA is for COMPARE BLOCK 0 and CMP SELB is for COMPARE BLOCK 1.

               

            You are right, that is my misunderstanding.

               

             

               

            Best regards.

               

             

               

            Teddy
