Facing problem during simulation using external .txt file as stimulus

Analog Design

 Hi ,

     I am giving two column (time/voltage ) .txt file  as  stimulus in spectre  . But during simulation the error coming as like below 

"Error  found by spectre during circuit read in" .

  • Managed to look at your attachment. You included the netlist rather than the input.scs (sorry, I probably should have made that clear) and as such I can't see the erroneous "include" statement of your text file (i.e. the stimulus file), but that would definitely cause this problem. The full error message pinpoints that:

    Error found by spectre during circuit read-in.
        "/home/mudassar/simulation/test_1/spectre/schematic/netlist/stimuli/text.txt" 1: Unexpected numeric value "0.000000000000".

     It's complaining about reading the file during "circuit read-in" and the numeric value is clearly indicating that it's your time-voltage file. 

     So remove the stimulus file setting in ADE, and then it should work. Not sure why you thought you needed to set that (I didn't say that you should do that in my previous replies)?

    Regards,

    Andrew.
