Toolset: ISE/ModelSim_PE/VHDL
I've been asked to modify one of my designs for another application so decided it was time to parameterize it as much of it as possible. I ran into a roadblock changing configuration of CoreGen devices, so was simply going to force the eventual user to go through the GUI for any modifications. Then I RTFM. ;-)
In the Comparator V9.0 Product Specification there an example of direct instantiation (Page 7), which looks like it'll save me a lot of headaches. I can simply use the generics I already have to manipulate the core. My problem is that ISE doesn't find the comparator in the library. I've had the problem (with ModelSim) where the libraries change and I'm pointing to an old copy but I don't know where to tell ISE where the libraries are. I've always used the GUI to generate cores before, but I really like the idea of direct instantiation. I can make my designs far more flexible without a whole lot of work. Anyone with a cluestick?
