Hi everyone,
I would like to develop an Arbiter PUF on a Cyclone III Starter Kit (
http://people.csail.mit.edu/devadas/pubs/puf-dac07.pdf). The result of this circuit is very dependant on the implementation, and so I would like to make a circuit the more symmetrical as I can.
To develop my circuit, I would like to know if there is a way to route signals to a specific LUT input. For example, I would like to know if I can assign a signal to the input port DataA of a LUT and when I duplicate this function, the signal is still assigned to the good port.
I already tried to back annotate one LUT after an ECO change in the Chip Planner, and when I compile or recompile this one, the signal is assigned to the right port but when I instantiate multiple LUTs, from the first one, the assignment is lost and the signal is assigned to a random LUT input.
I also tried to edit an EDIF file but I’ve got some problems with the LOCAL_INTERCONNECT values because when I change the value of the signals’ port the compiler show me an error on those values.
