    How to place bypass capacitor for BG575 BGA package

    bypass capacitor placement layout power via I used xilinx XC2V2000-BG575 package. The Vcore voltage is 1.5V with near 40 Vcore pin, and 3.3V IO voltage with 50 pin. i think it's difficult to put each power pin with one bypass capacitor as close as possible to the chip. Anyone can give some...

    How to generate the testbench for signal process algorithim?

    thank juripero, thank for your help. But if i want to add channel model, such as fade, interference, how can i deal with it. The In-build function in verilog simulation is too little.

    How to generate the testbench for signal process algorithim?

    I want to generate plenty of data as stimulation to simulate the digital receiver design usued verilog. how to generate the modulation data. I know the matlab can do it, but the data file pre-generate can not used for long time simulation because of i need read a very large data file into the...
