I have noticed that i get this problem when i try to simulate with opamps also, when configured with feedback. Pspice Convergence Problem In Transient Analysis At Time I have zipped my design and put it up on: http://www.its.caltech.edu/~hiszpans/preamp.zip The model uses an OPA134, created by following the instructions at: http://focus.ti.com/lit/an/sloa070/sloa070.pdf and using the SPICE model provided by TI Subject: ERROR -- Convergence problem in transient analysis at Time = 482.5E-06 Time step = 447.0E-15, minimum allowable step size = 600.0E-15 These voltages failed to converge: V(SQUARE-WAVE) = 6.857V \ http://www.edaboard.com/thread55832.html Visit Now Training Training OverviewGet the most out of your investment in Cadence technologies through a wide range of training offerings.

i don't know about Edemout. Quote:You need a 0 (ground) symbol out of the source library. I have noticed that i get this problem when i try to simulate with opamps also, when configured with feedback. Did you change symbols?

  • Try the following in your simulation Code: .OPTIONS ITL1=400 This is the number of iterations the simulator will perform before giving up.
  • too bad i can't probe an aborted sim.

  • i don't know what time step has to do with it.
  • The time now is 13:27.
  • Part 1 focused on construction of a test circuit and the AXEpad IDE; part 2 covers the PICAXE Editor 6 IDE.

I am not familiar with that version of spice, but the -15000 when it is trying to linearize the circuit about the bias point looks suspicious. Here is what i get from pspice --------------- Simulation Profile: SCHEMATIC1-trial --------------- Simulation running... ** circuit file for profile: trial Reading and checking circuit Circuit read in and checked, no errors I have yet another problem with Pspice ERROR -- Convergence problem in bias point calculation Last node voltages tried were: NODE VOLTAGE NODE VOLTAGE NODE VOLTAGE NODE VOLTAGE ( a0) 0.0000 http://indywebshop.com/failed-to/failed-to-extract-ist-dll-error-is-2.php No, create an account now.
