New ContributorFPGAs with Feedback issues
I am going to be doing some proprietary experimental circuit design using an FPGA and these circuits will require feedback in some instances. Do any of your FPGs allow for feedback because Intel's Cyclone calls this an error and will not synthesize?
I am a new rep for a small software company and I don't have any experience with FPGAs. Please answer the question above if anything but if you want to help even more please help me rewrite the paragraph below.
FPGAs are a development tool used to simulate a circuit of interest. They're programmed using the manufacturers software and can be used to simulate any circuit. This is especially important to engineers creating novel circuits because they don't have to actually make the circuit before they test it. However these circuits need to be massaged by the programmer into code accepted by the software compiler. Lots of programs don't run initially and need to be debugged to function. These circuits run from start to finish in ladder logic sequence.
Thank you to all who respond.
Here is how I would rewrite your paragraph (rather significantly):
FPGAs are programmable devices that allow you to create custom logic designs in hardware without the need to build an ASIC or use multiple chips on a board. They can be reprogrammed with the same or a different design "in situ" at any time. You can simulate an FPGA design in a simulation tool, but that design can then be implemented with full functionality in the FPGA. An FPGA design is created, compiled, and programmed using the manufacturer's software. This is especially important to engineers creating novel circuits because they don't require any other hardware on their board to implement the circuit other than just the FPGA. FPGA designs are typically created in a hardware description language (HDL) to describe the behavior of the circuit and then compiled by the design software. The design software has many debugging tools to help with everything from creating the initial design all the way through testing the design while it's running in the FPGA.
Side note: while FPGAs can be used for ASIC prototyping (which I think is what you are thinking about here), this is not a huge part of the development base for these devices.
