      Hello tanveer,
      It can be because of random seed thing. Well i suggest you to double click on every component you have used in your design especially the active components , you may see a simulation tab namely random , click on that and untick the generate seed option. It will definitely make your results stable. I hope you fing it helpful.

      hi Tanveer,
      yeah you try it first and I believe it is the main problem that is causing your results to vary every time you simulate your design. I am telling you this because I had faced same problem initially. I hope it helps you.
      Best Regards

      Hi Tanveer,
      I agree with aabid sir point as he said that it occurs with Random Seed Index. So, first untick that.

      Hello Abid, I completely agree to your reply”It can be because of random seed thing. Well i suggest you to double click on every component you have used in your design especially the active components , you may see a simulation tab namely random , click on that and untick the generate seed option. It will definitely make your results stable.” This random generation of values is meant for inserting a noisy signal in lossy conditions. Switching the random generation off reals generates the required results.
      Thanks for your kind suggestions.

      Hi Tanveer,
      If you continuously facing such problems.
      Now design the sane networks in new lAYOUT by using the same layout parameters.
      Because sometimes, when we use previous layout we didn’t various parameters of layout.
      So, i suggest to use new layout.
      And check the results at every output port of each components.
      Hope it will help you.
