<p>This thesis proposes a new method to detect routing switch alterations on FPGAs in real-time. By sampling the circuit path at the source and destination, and comparing the samples, it is possible to find out if there has been a routing change in the circuit path. We compare and contrast this probing method with previously established techniques such as Cyclic Redundancy Checks, Built-in-self-tests, Triple Modular Redundancy, Duplication with Comparison, and redesigning the FPGA. The probe method finds the routing error in one clock cycle, using the pre-existing elements on the FPGA, while the FPGA is still operational. This method works on all FPGAs that use the Wilton style switchbox. An automated tool for probing the design circuit is presented in this thesis that applies the probe scheme on a circuit built on the Xilinx Virtex-4 FPGA.</p> / Master of Applied Science (MASc)
