I used Xilinx tool and modelsim but it is too big for me and I don't like this VHDL coding program.
besides, Xilinx tool make my computer slow. after I install Xilinx tool, my computer sometimes freeze up. this really annoy me.
what is your favorite VHDL coding program? I want VHDL program more light and faster than xilinx tool. please tell me VHDL program what do you prefer to use it.
upgrade ur computer.. XILINX wudnt freeze ur machine :d lolz..
modelsim is a good simulator for v-hdl and verilog.. system c to a certain extent.. give it a shot.. dunt complain that insallin that slows down ur system :d
Your Computer might have become slow due to Adware or Spyware ..check for them. Usually Xilinix tools are user and computer friendly. They are tested a lot on different configuration before releasing their software
ModelSim is really a cool tool. You can also use Active-HDL from ALDEC. Also you can use Altera's Quartus (available for free).
Running slowly should not be a program using any of the tools suggested as long as you are not running something massively huge (which I am sure you are not doing !!). Also, in the CAD tools, normally the compilation does not take that much long time as other activities ( like synthesis) might take.
