• Unable to resolve the error of convergence

  I have a thermostat to diode based using a 1N4148 as reverse engineering temperature sensor.

  I entered the circuit in the schematic editor, but whatever I do, he refuses to perform the simulation!  I get an immediate "Timestep too small" simulation error, and the assistance of convergence can not solve.

  I don't * think * I have all "stupid" that would cause the simulation to fail, but maybe I've missed something obvious.

  As a "Starter for 10 points" How can I get the simulation to run?

  As a '30-point Bonus question' how can I change the temperature of the led (say) 150C while leaving the rest of the simulation at nominal temperature?

  Hello

  We use a better model for the LM324N SPICE:

  • Double-click this component (U3A) to open its Properties.
  
  
  • Select the value and click the replace button.
  
  
  • Make sure the LM324N is selected in the browser pane.
  
  
  • Visit the Model FAB/ID field and select the model of National Semiconductor National (it is a model of 5 pins, more precision).
  
  
  • Click OK, select the section.
  
  
  • Repeat this procedure for the section B, C and D.

  Run the simulation, this convergence error should disappear. I have attached your circuit with this change.

  I hope this helps.

  BTU were not up to the solution to this.

  Thank you.

  According to the OPA381 data sheet, it is designed to work with capacitive loads up to 100 pF, by inverting the configurations of the amplifier and as an amplifier to transimpedance, which is usually used with a current input (very low) and comments fairly large resistances.  Your circuit works with capacitive loads of ~ 5 uF (50000 x the design load), unity gain, setting up inverted, and with an input voltage.  Depending on how the model for the OPA381 manages these outside normal range values, convergence errors are not too surprising.

  The network of coupling between stages has a low pass cut off ~1.3 Hz. The first entry of the step network is more complicated but also the limits of bandwidth at very low frequencies.

  What is this supposed to do?

  I faked coupling and feedback networks (assuming ideal unity gain amplifiers). It is the output with a 1 volt of entry.

• convergence in the mosfet driver NCP5355D circuit, could be "bootstrap" error?

  Hello

  I use the Multisim 13.0.1. There is a driver 8 pin mosfet NCP5355D available in the library. I wanted to use it for switching half-bridge MOSFET transistors, but a simulation error. Report says that "convergent transitional time calculation not '.

  I've included the circuit with the driver door, as well as the circuit with pulsed voltage sources separate for switching MOSFETs, which could provide an overview of what I intend to achieve with the driver door.

  I have also tried to set up the driver door step by step - I started VS, CO, EN, PGND simulation aside mistakes and haven't got pine then; but when I started to connect pins STB and DRN, convergence error has occurred. If the error of convergence is resulting from errors in STB and DRN pins?

  For convenience, the datasheet of NCP5355D is also attached here, where the application example connections are included.

  Waiting for your ideas and thanks in advance!

  I don't have a Multisim, so I can't see your circuits but have a few general comments.

  1 MOSFET driver models often use switches and these can lead to problems of convergence. This is because the action of switching introduced a strong nonlinearity in the model.  I wrote my own template using transmission lines for delay and nonlinear dependent sources with functions tanh rather than hard switches.

  2. If you do not need to model the detailed driver behavior, using pulse sources with up/down times as long as possible without changing the behavior of the MOSFET can be a better choice.

  3. There are books written on how to deal with the problems of convergence of SPICES. That's what I found useful to one of them:

  * From inside Spice by Kielkowski
  AIDS convergence
  * Choose RELTOL appropriate
  * set VNTOL = RELTOL * Vsmall
  * set = RELTOL ABSTOL * Ismall
  * the value = 1/Rp GMIN where Rp is the parasitic resistance that
  will have a minimal effect when added to the circuit.
  * models of semiconductor should have resistance non-zero
  * RS (diode), RC (BJT), RD, RS (FET)
  * Make ITL1 = 500 (limit of iterations DC OP)
  * use. NODESET
  * Use source stepping ITL6 = 500
  * Convergence transitional AIDS
  * Add capacitance of device models:
  * The CJO (diode), ECJ, CJC, SYC (BJT), CDG, CGS (JFET)
  * CGDO, CASE CGBO, CBD, CBS, CJ, CJSW

• How to write to .subckt with the function I - V

  Hi all

  Now, I am trying to build a Spice model for a type of diode high voltage for 13 Multisim. Because I do not have the LED electronic settings, and I only have the function of the I - V, I tried to write a file .subckt for him.

  Assuming that the anode is A1 and the cathode is A2, the current flowing through the diode can be expressed only by the function:

  I=((0.581*(V(A1)-V(A2))*(V(A1)-V(A2))/3/3-18.4*(V(A1)-V(A2))/3+144.66)/1000)*U((V(A1)-V(A2))-53)

  With her, I wrote a .subckt:

  . SUBCKT LED A1 A2
  B1 A2 A1 I=((0.581*(V(A1)-V(A2))*(V(A1)-V(A2))/3/3-18.4*(V(A1)-V(A2))/3+144.66)/1000)*U((V(A1)-V(A2))-53)
  . ENDS LED

  This model works well under the IV parser in Multisim 13, but when I connect 2 or 3 of them in series and make a simple circuit simulation, I always get the error report and not always not correct the error.

  Any body can help me to check if my .subckt is correct or not? Thank you.

  It seems that the convergence error is caused by a discontinuity the diode to connection 53V.  Run DC scan using the test circuit.

  

  To prevent the discontinuity, use the express following with the fi works instead. You can give it a small current when V (A1, A2) is less to 0V.

  B1 A1 A2 I=if(((V(A1)-V(A2))-51)>0,((0.581*(V(A1)-V(A2))*(V(A1)-V(A2))/3/3-18.4*(V(A1)-V(A2))/3+144.66)/1000),-230u)

  The attached circuit have a resistance using convergence.

  You can simplify your expression for readability:

  -(V, (A1), (A2) V) = V (A1, A2)

  -If you can do the expression in this form, it will simply be the calculation ax ^ 2 + bx + c

• circuit relay simple keep generating errors of convergence.

  I am trying to simulate a circuit simple relay and continue to get errors of convergence, Timestep too small.  I tried a number of changes to the parameters, such as the given input parameters to zero, without success.

  Finally got the operation of the circuit. It seems that you need to change the upper limit transient iteration in custom Analysis Options (under Transient tab) and then it starts to work.

• Convergence Assistant (error of the Op-Amp)

  Hi all

  This is my first post here, and I am familiar with Multisim on a basic level. I created my sim file based on a pattern that I was not designed. I get the error message:

  A simulation error occurred. You want to run the wizard of Convergence to try to resolve this problem automatically?

  Most every time I hit Yes, convergence assistant is able to solve the problem, but he is unable to fix this circuit. I think the problem is with the amplifiers and tried to tinker around to fix.

  I have included:

  1. JPG file sim
  2. Schema of the source GIF
  3. Multisim file

  Any ideas? Thank you.

  Moreover, it is a pulse width modulator used to keep the constant running rms.

  Hello

  I took a glance at your circuit, and it seems that the question of convergence is in the template that you use.  The model is a 3-terminal op amp; in other words, only the input and output pins are modeled and not the power supply.  This leads to problems of in your circuit in question because you have some operational amplifiers in open-loop configurations expected that output will be cut to supply voltages.  But because the power supplies are not modeled, the output is not be truncated, and so very great tension values produce outputs.

  I have replaced the template you are currently using in the circuit (ITI/LM324A) by another who does not model power supply (ITI/LM324A_2).  It seems that solved the issue of convergence.  The modified file is attached.  There are also specific models to the LM324 provider in the database in case you use a specific component of the seller (depending on your version of Multisim).

  Let us know if that fixes the problem.

• Problem of Convergence HB in co-simulation EM-circuit

  Hello

  It would be really helpful if someone could take a look at the problem of simulation in the attached draft. I get errors from simulation - "step for source stepping size has declined under a permissible minimum value."and"poor convergence in the analysis of AC/DC (rel/abs err = 2,000 / 0.000) the biggest change (41) node in the node (46) maximum voltage = 53.076 minimum voltage in the node (MET_BASE!" _S12_LD1.

"(I) =-1735"

  Despite trying most of the suggested solutions enumerated using the particular error message, the problem persists. What I do wrong here in the configuration of the simulation?

  Thank you much in advance.

  You check the use frequency of the project on block of EXTRACT properties > frequencies tab.  So the structure of the MA is only simulated at frequencies of input: DC and not harmonics 5 simulation HB is taken into account.  So microwave Office must extrapolate at these frequencies. Your block EXTRACT frequencies should be defined to include 0, 1, 2, 3, 4 and 5 times each frequency simulation... .to you chanage the number of harmonics in the harmonic balance options.  You can also simply define the block EXTRACT sweep from 0 to 10 GHz.  Whatever it is, the simulation of EM will take more time, of course.  If AXIEM does not converge on a response, change the properties of block of EXTRACT > AXIEM tab, click the secondary Show button and under Advanced frequency sweeping (AFS), increase Max # sim points.

  For circuits that include models not linear, you must include the frequency = 0 even for linear measurements, for the accurate calculation of the DC polarization.

• OSPF quick Convergence on specific links in a network.

  Hello

  I have a couple of question regarding the acceleration of the convergence of OSPF to help me understand it better.

  In this case, I would like to speed up the OSPF convergence failure occurred between two specific locations without causing problems for the other routers on the network.  These two sites are part of the area of the spine. The two communities have two connection point to point between them on two different routers at each end.

  R1---(Serv Provider1) - R3

  SiteA                                                             Site B

  ---(Serv fournisseur 2) - R4 R2

  All I see there are two main factors controlling the rapid convergence of OSPF.

  1. the breach of the detection time.

  2. propagation of error / time recalulation FPS.

  The first factor - failure detection time can be reduced by decreasing the OSPF Hello/dead or using BFD programmable intervals to detect the failure.  What is the best option?

  Of what I see if using timers in OSPF Hello/dead I should only match values of timer on router interfaces on part and on the other of my links point to point and could leave other interfaces as they are. Is this correct?

  Consider the second part - by strangling the timers of SPF, OSPF SPF computation time is reduced. New account my two links Point to what I can fix timers on the routers to share back and forth across the point-to-point link or I have to put the same on all routers in the OSPF network.

  ("Timers SPF throttle"command).

  Hi Pat,

  Regarding the SPF hold timers. to confirm is there any issue with having different values on different routers in the network. I presume not as the value is random anyway?
  

  the values to see the SPFA is always a compromise: on the one hand you don't want a permanent recalculation caused by a link heartbeat, on the other hand, expect a rapid convergence. It means finding values that meet the requirements in terms of stability and convergence at the same time.

  I think that the main problem with different values in a box is micro-boucles. Since the new calculation (and update routing tables) not be made never exactly at the same time on routers, link-state routing protocols can produce short times with micro-boucles once the topology changes because some transfer tables are updated as soon as the others (we are talking about tens-hundreds of milliseconds).

  If you change the FPS-timer to say that 1 second or even less and other routers in the region still have the default (which is 5 seconds), the period of time where are micro-boucles may occur could be considerably long and that there could be a side effect, according to the topology/design.

  Hope that helps

• Power supply error after converting old .vmx file

  To start, that's what I'm working with:

  VMWare ESXi 4.1.0 (and vSphere client)

  VMWare vCenter Converter Stand alone

  What I'm trying to accomplish is to take an older VMWare machine, convert it, and then add it in the new client. Problem is after I convert the old file, transfer it to the data store, then add the inventory on what it will not feed machine and I get the following error message:

  I am new to all this installation of VMWare server so I am at a loss to know what to do to solve this problem. Any help will be appreciated.

  Welcome to the community,

  Problem is once I have converted the old file, download on the data store, and then add the machine to the inventory...

  Could you explain what exactly you were doing.

  • What is product VMware has been the virtual machine running before you converted?
  • How do you have it convert?
  • Why don't you use the converter to convert the virtual machine directly to ESXi, instead of convert and download?

• Uninstall software update Apple says error in seller contact package package unstaller

  Try to get itunes working to make a backup of my faulty iphone before repair.

  First-itunes does not start says error. I'm trying to fix it, who said success but same error when you try to start it.

  Then uninstall completely worked. Then reinstall that seemed to be over except for a message "an older version of Apple software update already exists" then he went down and install itunes apparently had not been completed.

  Then I try to remove the update from the apple software and executed by an error in the installation program - it says there is an error in the installation and contact the supplier of the installation package. Same error if I run the uninstall command line program.

  Try to repair the Apple Software Update of programs & features Control Panel and then try to update iTunes again.

  For general advice, see troubleshooting problems with iTunes for Windows updates.

  The steps described in the second case are a guide to remove everything related to iTunes and then rebuild what is often a good starting point, unless the symptoms indicate a more specific approach.

  Review the other boxes and other support documents list to the bottom of the page, in case one of them applies.

  The more information box has direct links with the current and recent if you have problems to download, must revert to an older version or want to try the version of iTunes for Windows (64-bit - for older video cards) as a workaround for problems with installation or operation, or compatibility with third-party software.

  Backups of your library and device should be affected by these measures but there are links to backup and recovery advice there.

  The way in which your external block If is currently based, the script can't do anything when this book is in the ignoredVolumes, it can not yet test the runScript value. Try something like this:

  If the present book is in the ignoredVolumes then

  game runScript to 1

  on the other

  if (the present book as text is not '. ') DS_Store') then

  if there are alias (POSIX (' / Volumes / "& the present book) as text file ) then game runScript to 2

  end if

  end if

  
  

  Of course, you need to remove a "end if' the end of the script.

• Display Rotation error

  Hello

  I had a problem with the rotation of the screen under macOS Sierra function. As the screen rotates, there is an error that pop up and later that I'm unable to get into system-> Display Preferences. It is for me a "mistake preferably: County not load display preferences" message and I was unable to rotate the screen back. I started from the system in safe mode and temporarily solved the problem. But if I want to rotate the screen again, it pops up the same error again. I was using the rotation function pretty well in OS X El Capitan. But since I updated to macOS Sierra, I had this problem.

  I wanted to know if there is a lasting solution to this problem.

  I'm using macOS Sierra on MacBook (13-inch, early 2015) Air with processor 1.6 Ghz Intel Core i5 and 8 GB memory DDR3 at 1600 MHz with 128 GB of storage.

  Hello PavanGJ,

  Thank you for using communities Support from Apple. I see that since upgrading to Mac OS Sierra problems of screen rotation. The preferences window does not. I know how it is important for your Mac to work reliably. I'll be more than happy to help.

  Great job to test mode without failure. In Safe Mode disables most of the third-party services, it could be a compatibility problem with an application that you have. Check out this article:

  OS X El Capitan: If you have problems with startup items

  You can not hold account that the title suggests it's to El Capitan. It applies to macOS Sierra as well.
