I want to learn VHDL myself for DSP and digital communication usage. Any good free software recommend? |

| 1 | knoxville | What software do you need? If you use Xilinx you can use Free Xilinx ISE | 2008/8/28 06:06 |
| 2 | mxg330 | I don't know which one I want to use. Maybe Xilinx or @ltera? What is the most common use in industry these days? Anywebsite to download the software? | 2008/8/28 06:06 |
| 3 | ken7976 | I suggest go for ModelSim or Xilinx. Xilinx will help you to work on FPGA but Modelsim you can only code but cannot check the results on board. You can check the results on screen. thanks |

| 4 | rickli | A good way to get started is to buy an inexpensive FPGA development kit (prices start around $150 US) that includes whatever hardware features are interesting to you (audio, video, communications, whatever). Then you can install the (enormous) software and start experimenting. You can simulate your HDL in the simulator (ModelSim is popular), and then synthesize it, download it into an FPGA, and watch it run. Or you can simply download the software and run it without any hardware. I think you can download a free student version of ModelSim directly from www.model.com. But I think it's more fun to have real hardware to try out audio processing, video processing, etc. I use Xilinx. Here are their development kits: http://www.xilinx.com/products/devboards/index.htm Here's the free ISE WebPACK software. It supports all the smaller Xilinx devices, but not the big ones: http://www.xilinx.com/ise/logic_design_prod/webpack.htm _Altera has nice FPGA products and kits too, but I'm not familiar with them. |

| 5 | bubulu | You can use the free vhdl simulator http://ghdl.free.fr/ Please see a lot of examples of VHDL and VERILOG at http://bknpk.no-ip.biz/ |

| 6 | 398338 | thx all.anyone can suggest the model name of very cheap development kit? by the way,why some of then using c language for fpga? |

| 7 | netlgc | Here are several low-cost Xilinx FPGA kits based on various Spartan-3 family FPGAs: http://www.xilinx.com/products/boards/s3_sk_promo.htm Most of them are called "Spartan-3xx Starter Kit". The more expensive ones are usually called development kits. Some of the kits include MicroBlaze development tools. MicroBlaze is a 32-bit soft processor core that you can drop into the FPGA, and then program it using a C compiler. Sometimes it's nice to have a general-purpose processor in your FPGA project. |

| 8 | wy830115 | what is the risk of damaging these kits as then i will learn on it? because i wished to do that but i am always afraid of being burned | 2008/8/28 06:06 |
| 9 | fujun2013 | I haven't heard of anyone blowing up a development kit by downloading bad code into it, if that's what you mean. If you download a large high-clock-frequency design into an FPGA, you should check the FPGA temperature, and if necessary install a small heatsink or fan. Most designs don't need it. As with any open electronics, be careful handling the board. Avoid static electricity zaps. Don't drop metallic things onto the board while it's running. Don't apply excessive voltages to the I/O connectors. The usual precautions. |

| 10 | htc2498 | thx echo. are those kits that you mentioned suitable for digital comms., like error control coding, interleaving, modulation, fft, dsp? by the way, why sometime peoples using c and sometime using vhdl? both of them also ok for the kits you mentioned? which language is more often used in industry for fpga? thx! |
