I have a very self contained program ( the input data is preloaded using MIF files into block ram, processed and the output is again stored in block RAM ). the only ports to my program are clock, reset and a 1-bit output ( just to turn an LED on to me the program is done ). I am trying to run power analyzer to generate more accurate power estimates. However, the procedures online all talk about using a test bench ( they all say to compile my .vhd file to a .vho file and run that along with the test bench in model sim ). However, since i have just clock and reset i just quickly did the toggling of those using a TCL file in ModelSim for simulation purposes and didnt need to use a test bench.
When i tried to simulate using the .vho file, a lot of the signals from my original file were no longer present. so i wasnt able to run simulation.
1. is it a must to use a test bench to get accurate power analyser estimates? if so, would a test bench that just toggles clock and reset work?
2. since there is only one output to my program, if i write a simple test bench and run it will that still generate enough toggle data to give me an accurate power number?
thank you!
