    On a chip, adding 2^256-1 and 1 may not equal 2^256 when:
    1. Your destination register is 256 bits.
    2. Your destination register is in a different clock domain.
    3. Your timing constraints are wrong.
    4. Your power grid cannot support switching 256 registers.

    Functional simulations will only catch #1.

    List of FPGA prototyping boards. Xilinx software is free for certain FPGAs. http://www.fpga-faq.com/FPGA_Boards.shtml For books, the only one I know of with an emphasis on synthesis results that includes both VHDL and Verilog is "HDL Chip Design" by Douglas J. Smith. I highly recommend Verilog over VHDL even though I learned VHDL first. Also Xilinx has obscene amounts of documentation on their websitehttp://www.xilinx.com/support/documentation/. Some of their whitepapers and app notes cover general logic design techniques.

    Traffic laws vary by state. 2x2 riding is allowed in Texas but was NOT in Massachusetts until April 15th of 2009 http://www.mass.gov/legis/laws/mgl/85-11b.htm. I'm curious which states allow bikes to ignore traffic control devices because the above two most certainly do not.

    ...you know that a small random sample of the population tells you what the general population is like to a very high degree of certainty.

    Statistics allows you to extrapolate results from a small sample set if, and only if, the the entire sample set follows a known statistical model.

    There is no such thing as a right to the market value of one's property--which only exists in the minds of others to begin with.

    I wish housing values weren't guaranteed either. Unfortunately the federal government has recently passed some extremely large spending programs designed specifically to do just that.

    This is true. However in this use case the energy radiates mostly cylindrically so to deprive other users of the signal the power receiver would have to be in directly between the transmitter and the signal receiver. Boats deal with this all the time when large freighters block everything(radio, radar, GPS). Most electromagnetic radiation is lost as heat anyway.

    Although the nominal corporate tax rate is not that low, the actual (average) taxes paid by corporations is quite low compared to other developed countries because of the convoluted tax breaks written into the law.

    Citation please. I'd like to see an example of a US company legally pay less than 20% on income of at least 10 million in profits.

    I'll use Intel as an example, since they post excellent reports and are a large multinational corporation. http://www.intc.com/intelAR2008/financial/statements/note23/index.html Notice their effective rate of between 28% and 31%(make sure to read about the 24%). Amazing that the government gives them tax credits to do R&D and manufacturing locally. You'd think that they'd just lower the tax rate.

    Is that low compared to other nations? This data says no: http://www.kpmg.com/SiteCollectionDocuments/Corporate-and-Indirect-Tax-Rate-Survey-2008v2.pdf The average rate in 2008 is 25.9%. In fact Intel's effective rate is higher than over 70% of other nations including the entire EU which has been lowering corporate taxes over the past decade.

    There's already a class of games that require a monthly payment. Most of the CAE software I use has yearly licenses. It seems the only problem instituting this type of model for games is that most people would not pay for more than one month, due to their usage patterns.

  21. Re:Verilog is a programming language on VHDL or Verilog For Learning FPGAs? · · Score: 1

    Synthesizable Verilog is no more a programming language than a SPICE netlist or a GDS file is.

  22. Re:Where are you located? on VHDL or Verilog For Learning FPGAs? · · Score: 1
    Learn Verilog. It's been a while since I've used VHDL but the following is why I would not consider using it again.
    • VHDL's strong typing will cause you hours of lost work because of silly things like the differences between std_logic_vector and unsigned. Others claim this is a feature as it prevents bugs due to type conversions. This should be a non-issue when using Verilog as your test suite should test everything. Plus decent simulators/synthesis tools have lint functions.
    • VHDL is far too verbose. It requires replicating the entity definition before instancing it. Now when you change ports(and large designs will require MANY port changes) you get to change them in 3 places instead of 2. In ASIC applications, netlist brevity becomes very important when gate-level fixes need to be made.
    • Many tools do not like VHDL. At least two that I know of require compiling libraries first. With Verilog you can usually just throw a bunch of files at them and the tool can elaborate the design. In ASIC development, you very well may use 5-6 tools other than the simulator and synthesis tool.
    • SystemVerilog is a train wreck, but is advancing Verilog adoption.

    You may want to consider schematic entry if your design is simple enough. At the very least, look at the floorplan of your synthesized designs so you can how much logic it took for each module.
