    xilinx bit files - some questions

    Re: xilinx bit files For the same design you may have different configuration commands (incl. parameters) in the bitstream. For example, you can specify either using Jtag clock or CCLK.

    Looking for software that converts Matlab code to VHDL

    matlab to vhdl converter software Tools such as DSP Builder from @ltera or System generator from Xilinx can be used to generate HDL code directly from Simulink Blockset. Both both tools are not a kind of High-level synthesis tools, whereas the compiler from AccelChip performs high-level...

    System C synthesis - a question

    Re: System C synthesis I think if you want to design a System-on-a-Chip, which consists of both hardware and software, then SystemC is a good choice as a modeling language. However, SystemC is based on a refinement design approach. That means, you can model the system at different levels of...

    What software need to work with AT94K Series?

    (1) Free tools (min. requirement): Amtel IDS 7.5 for FPGA mapping and bitstream generation + AVR compiler and debugger (2) Commercial tools (optional): ModelSim (HDL simulation) + LeonardoSpectrum (FPGA synthesis) + Seamless CVE (for HW/SW cosimulation) (3) SystemDesigner (commercial) : (1) + (2)

    How often do you use IP core generators?

    Some FPGA vendors offer IP core generators (e.g. Core Generators from Xilinx) which can be used to generate netlists of circuit modules of various types and complexities for FPGA designs. My question is how often do you use these tools provided by FPGA vendors.

    HDL Entry vs. Schematic Entry Tool?

    In general, I don't use Schematic entry tools. But for some cases, using schematic tools to capture structure of a circuit (a regular datapath) may be useful.
