I am designing a Data acquisition system with a Texas instruments ADC, Inamps and a ST micro electronics micro controller. I am getting spice models for my inamps, differential amplifiers etc. so that I could do SPICE simulation using any spice softwares. ( I am currently using LT spice)
I wish to see the output of my ADC if I am providing an input signal with my simulated amplifiers and filters. I am getting an IBIS model of the ADC.
I am new to these IBIS models. I am not sure what it is used for. When I read some introductory papers, I understood it is also a behavior model. Is it possible to use any of the spice software to import this IBIS model with my existing SPICE models and give some input and get a transient analysis or FFT from the output.? If yes, which tool would be ideal for my application. I heard PSpice could do this. If anyone could give a starting point or show me the way to do it that would be great. Is it possible to use matlab/simulink to do it?
I am not designing an IC or anything, just to use the discrete components to design an embedded system.April 20, 2013 at 10:32 am #16427Rever75Guest
you can use the PSpice model editor to translate IBIS models to PSpice models: select File, New and from the Model menu select “IBIS Translator…” option. The model editor translates IBIS models up to 1.1 version, but with some changes you can modify a IBIS 2.1 version to make it 1.1 compatible. read more details here:
You could also use Intusoft’s IBIS2SPICE converter if you design with ICAP/4. The free version supports IBIS models up to 2.0 version. You can download it here
