Error while using Simulation Waveform Editor - Error while using Simulation Waveform Editor I was trying to use the Simulation Waveform Editor but I get an error when I try to run simulation. I have attached a screenshot of the error Could you please help me out Thank you Replies: Re: Error while using Simulation Waveform Editor Thank you that issue is resolved. Now I'm facing a new problem. I get an error saying : Error (suppressible): (vsim-3601) Iteration limit 5000 reached at time 25 ns. I am trying to simulate a simple RS Latch. My code is below and I have attached the screenshot of the error as well. I tried searching how to resolve this error. I read this can occur when there is an infinite loop, but I'm not sure how my code can end up in such a loop. Am I doing something wrong? I'm kinda new to Quartus as well module part1(clk, R, S, Q); input clk, R, S; output Q; wire R_g, S_g, Qa, Qb /* synthesis keep */; and(R_g, R, clk); and(S_g, S, clk); nor(Qa, R_g, Qb); nor(Qb, S_g, Qa); assign Q = Qa; endmodule Replies: Re: Error while using Simulation Waveform Editor Hi Vishvas, Remove the -novopt in your script and rerun the simulation. Thanks, Regards
