Vivado 2014. The outputs of the design are printed to the screen, and can be captured in a waveform viewer as the simulation runs to monitor the results. A test bench is essentially a “program” that tells the simulator (in our case, the Xilinx ISE Simulator, which will be referred to as ISim) what values to set the inputs to, and what outputs are expected for those inputs. 2010/09/18 You must show work with code and simulation results as appropriate. Tom Ma heeft 8 functies op zijn of haar profiel. This usually results in transactions being scheduled on output signals for some later time. Typically the disk blocks that make up a file are something like 4k bytes in size, and so the library buffers up smaller writes that you do until it has a full disk block, and then it writes that out all at once. But I guess this setup forms a loop or something and it would never end, the simulation keeps on running and my. Luckily when we use HLS we can really skip over a lot of the heavy lifting and let Vivado HLS implement the lower level Verilog / VHDL RTL Implementation.
