Hi, what's wrong with this model???

Mike_85_,

It appears the link to this model provides for an IBIS implementation only (I-V curves) and not SPICE.  While this gives you some idea on I/O transfer curves, it does not provide any functional implementation data.   Multisim does not currently support IBIS modeling, only true SPICE models are supported.

This is a D flip flop and there are several 'generic' models that can be easily adapted to fit some of the specifications of this device using a D-chip device.   I would suggest going to the TIL family of digital components and look for a similar device D flip flop device.   Look at the model and you'll see what parameters you can change.

This thread provides some additional details on the d_chip implementation (this is a customized Multisim 'X SPICE' model).

If you are interested in the exact I-V I/O characteristics, it is possible, but requires additional work and this is a more in depth topic than is intended for this forum.   Let me know and we can offline this topic if the exact I/O characteristic is needed.

Thanks for replying.

I checked the components family that you suggest to me. The D_FF and D_FF_POSSR are similar, but I have no idea how can I create my parametres. Can you please tell how can I change the parametres? 

Thanks in advance.

Mike_85_,

What specific parameters are you trying to adjust or match?  

To get I/O performance that matches a particular logic family, you may want to create a new part using the Model Maker.   If you create the part as digital (first step) you can select a logic family - the I/O of which will match the I-V performance of the family.   When you select the Pin type you can adjust in/out/tristate as needed depending on the I/O type.

To make it easier, copy the symbol from the existing TIL symbol and copy the model from the existing TIL model into your new custom part.   You can adjust some parameters for the logic behavior or in-out timing delay as is described in the d_chip guide (see previous post for the link).

Also when simulating digital parts in Multisim to make them sim realistically (based on logic family), make sure you set the Mixed mode simulation settings to 'real'. From menu, Simulate -> Mixed-mode simulation settings...  (Use Real pin models)

Hi, I want to give pulses to the driver IR2110 H bridge resonant inverter. Any information guide how to achive that? Can you please give an example about this ( sorry, I am not so familiar on this point ). Can I create these pulses using different component? For example using LM555 timer? Is there any example about that?
Thanks!!!!

Mike_85_,

Here is a simple LM555 astable multivibrator you can start working with.

Thanks a lot!!! I post a problem about IR2110. Can u please check this component also. I dont know which one works right
