Pspice These Devices Failed To Converge


About Us Electronics Point is a community for members to discuss, advise and debate electronics related topics. the schematic is just fig. 9.74 AoE 2nd ed. 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 i don't know what time step has to do with it. have a peek here

These supply currents failed to converge: I(X_U2.egnd) = 0.0765222 / 0.0069206 I(X_U3.egnd) = 0.0551153 / 0.0326354 I(X_U2.vb) = -3.18479e-005 / -2.39829e-005 I(X_U2.vlim) = 0.0230456 / 0.0225084 I(X_U2.vlp) = 5.98241e-006 / -2.19366e-007 Attached Files: trial_3.jpg File size: 46 KB Views: 975 hydro, Dec 23, 2003 #1 hydro New Member Joined: Jan 4, 2003 Messages: 17 Likes: 1 Location: athens,greece here is the netlist how high?

  4. The problem that I have is that PSPICE wants MT1 of the triac to be grounded.
  5. subject line "4046 PLL" in case it's hard to read, V1 is Pulse(0 5 0 1n 1n 8.33m 16.67m).

The model also uses a 1k and a 10k resistor for the feedback network and a VAC source (Vac = 1, Vdc = 0) as input to the non-inverting input of Pspice Convergence Problem In Transient Analysis At Time Newer Than: Search this thread only Search this forum only Display results as threads Useful Searches Recent Posts More...

It stops your simulation dead in its tracks and requires you to loosen the tolerances in the simulation in order to continue on.    When manually loosening the tolerances, it’s hard Learning Classes OrCAD Capture OrCAD Capture OrCAD Capture CIS Component Data Management PCB Editor Intro to OrCAD PCB Editor OrCAD PCB Editor Advanced PCB Editor PSpice Intro to PSpice Analog Simulation Electronics Forums Forums > Archive > Electronics Newsgroups > CAD > Forums Forums Quick Links Search Forums Recent Posts Project Logs Project Logs Quick Links Search Project Logs Most Active Members http://bashprofile.net/failed-to/wordpress-has-failed-to-upload-due-to-an-error-failed-to-write-file-to-disk.html 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

The circuit i have posted is a milliohm meter i got of i think the EDN website, if someone could try simulating it in Orcad Capture and see what happens i button at the bottom.     This brought up a dialog that allowed you to turn on AutoConverge and specify some tolerance limits for the AutoConverge function to stay within (ITL1, http://bashprofile.net/failed-to/failed-to-open-a-secure-terminal-session-key-exchange-failed.html i don't know about Edemout.
