input b; reg a; if(i) a = b; assign c = a; if i=0; then what is the value of c, should it be no value, or 0? c is of wire type, so it is not saved, so there is no output value, is this correct?...
I often hear that FPGAs have tens of thousands of gates, but isn't the size of an FPGA measured in logic units? Is there any relationship between the two? How do you estimate tens of thousands of gate...
Here are the pictures. It's too late, and there's nothing much to write. Just a brief explanation will suffice. If I remember anything else, I'll continue to add.This is the Spartan-6 development boar...
The MCU I use is F5438A, the master clock is 32M. The configuration of ADC12 is master clock, 8-bit resolution, 64 sampling clocks, A0A1A2A3 round sequence;
