I'm now using in-system sources and probes, because of the possibility to control the inputs of the unit under test... The con is that I need to modify che code to add these sources and probes... there exist some other tool simplier to use that do not require changes in my code? Thanks so much.FPGA debugging Hi! I'm relatively new in the world of FPGA programming. I wish to know a way to debug my circuit impleneted in an Altera FPGA. I heard about the following techique: implement the test hardware, the nios 2 processor and a uart. In this way I could communicate via pc to the nios 2 in order to set the inputs to my circuit and evaluate the outputs. Is this a usefull technique to debug my hardware? Where I can find documentations about this procedure? Or there exist a more easy way to debug my circuit in the FPGA? Thanks in advice for the answer.
