bdf designs and connections between multiple bdfs

Hello,

Issue: I want to design a fairly complex FPGA device using mostly .bdf schematics. Each schematic will be essentially a page in the overall multi-page system design and its documentation. For example, a page might be a 32 bit register with lots of gated inputs and outputs implemented in bdf.

Question: How do I connect the schematics/pages? How do I label page I/O so it can be connected at the system level and makes sense in the documentation? It would seem this is where Platform Designer comes in, but I’ve been unable to find info about it or otherwise that even gets me started.

Any tips greatly appreciated. Courses, videos, documents, etc. greatly appreciated. This seems about the most obvious of issues; surely there’s a step-by-step out there.

Many thanks,

Bill McDonald

    No, PD is a system design tool, where you add components (off-the-shelf IP or your own custom IP) and connect their interfaces together.

    A PD system can be the top-level in a Quartus project or it can be instantiated lower down in the project hierarchy.

      Hi sstrell,

      This is the second time you’ve gotten me unstuck, and I very much appreciate your help.

      One question about your reply: You refer to a “top-level schematic”. Is this done with Platform Designer, or is there another method?

      Again, many thanks!

      My best,

      Bill

    Ok, I think I understand. I can use the Block/Schematic Editor to design a higher-level schematic that ties my desgin elements e.g., registers, together the way I used it at the low-level to combine primitives to create the registers. Right?

    Many thanks,

    Bill

      Hello again,

      I've been playing w/Schematic/Block editor and am beginning to understand the relationship between .bdfs and .bsfs. I belive I'm back on track and will mark this as complete thanks to your help.

      Best regards,

      Bill
