I soldered a 15K chip resistor on the circuit board. After the circuit ran for a while, I measured the resistance in a short circuit and found that the resistance value became 3.6K. I don't know what ...
I built a simple orthogonal LC oscillator (quadrature). The phase noise is required to be -120dbc/hz. Mine can only be adjusted to -111dbc/hz. I would like to ask how to design it to meet the requirem...
I used synplify before, but now I use XST. But I don't know how to write some statements in UCF file. For example, I can write it like this with synplify, but how to change it with XST? INST genblk0.F...
The input is some randomly generated signals, and all these input signals are required to be output in sequence after a delay of 100 clock cycles (external clock). How should this be designed ? Thank ...
Yesterday, Feixue001 asked about the function of the small board. Here is an explanation: The small board is a CAN evaluation board. It can be used alone, but it needs to be equipped with an emulator....
