Hi all
I'm trying to get back into electronics after a few years of neglect, My design revolves around a hi speed adc operating at 1Ghz from Maxim.
So now I want to connect all the components together in PSpice. But the problem is the vendor doesn't provide a model for this ADC. So I guess I am forced to build a model of the ADC myself. I know this is a next to impossible task in spice. But all I want is to model an ADC at a behavioural level. I would like as many real worlds affects in the model as possible, but I hear thats a hard thing to do, so I would be happy with just a functional model of the ADC so I can proove my circuit in concept. What would be good is to have a model that accounts for the sample and hold, the conversion and the demultiplexed PECL outputs.
I don't know where to start with this. I have looked at VHDL-AMS which looks like that it can do the job. But I can't find a simulator in which I can use my spice parts of the circuit and conect it up to the AMS based ADC model. PSpice is great because you can simulate spice models as well as vhdl/verilog parts. But not VHDL-AMS.
I also looked at Matlab and Simulink. I think its possible to model such an ADC with these tools and then import the model back into pspice. But I have no resources on how to do this.
I'm sure people have modelled an ADC in there designs before. Can anybody point me in the right direction? Tools to use? Workarounds etc.?
