OpAmp Simulation in Cadence Spectre

Shahnaf
Hi, I have used OpAmp symbol from Solutions library (default library of cadence). As an initial step, I have simulated a basic circuit in Op Amp. But I am not getting the desired output. Moreover, I have checked the cadence simulation manual for Op Amp. I found something difference in the symbol (from Solutions library) to that of the Cadence manual. Can you please let me know where I am wrong and what needs to be corrected? Thanks, Shahnaz

  • Well, you didn't answer my question about the path to the Solutions library, but the cds.lib is not a "default" cds.lib but one that you have in that particular directory, and is not something provided by Cadence. Similarly any manual provided by the University of Mexico is unlikely to be something that I would be familiar with. Maybe this Solutions library was provide by the University of Mexico too?

    Since the Solutions library nor the manual you are referring to are anything I have ever seen before, nor something I have access to, I'm afraid there is nothing I can do to help. I would suggest that you contact the University of Mexico since the manual (and quite possibly the library) is from them.

    I'm slightly mystified as to how you thought anyone could help you with data which we can't see, especially if you knew that the manual you were referring to was from a University.

    Also shows the benefit of providing sufficient information at the beginning. A lot of time has been wasted here trying to track down what your actual issue is. Remember this is a community forum, and is answered by people in their own time (including me - it is not part of my job at Cadence to respond on this forum).

    Regards,

    Andrew.
