Inserted a ChipScope probe into the design. Problems : RTL optimization problem. When we synthesized our design with EDK, the ISE tool automatically ran its optimizations, and “optimized away” some of our signals, for efficiency. This phenomena was very problematic on our behalf because we wanted students to be able to see all the design signals. Signals naming problem. After the synthesis stage, some of our original signals received different names, as a part of the synthesis process. It was very difficult to distinguish which were the relevant signals.

Solution for the post synthesis naming/optimizing problem There were several stages for the solution :There were several stages for the solution : –First we synthesized our periphery in an independent way using ISE. –We learned which libraries are needed in order for us to be able to “dive into” modules in our design. –We found a method of synthesis which preserves the signal names. –We then transferred this knowledge to the EDK environment, and found a method of synthesizing our design with command line instructions for the ISE. –Finally the synthesized peripheries kept their original names and we are now able to monitor all signals of our design. –The signals were also not optimized away There were several stages for the solution :There were several stages for the solution : –First we synthesized our periphery in an independent way using ISE. –We learned which libraries are needed in order for us to be able to “dive into” modules in our design. –We found a method of synthesis which preserves the signal names. –We then transferred this knowledge to the EDK environment, and found a method of synthesizing our design with command line instructions for the ISE. –Finally the synthesized peripheries kept their original names and we are now able to monitor all signals of our design. –The signals were also not optimized away
