一般这种情况是指 你在不同的进程里面同时对同一个寄存器进行了赋值 当在不同进程里面对同一个寄存器赋值的时候 编译器无法判断寄存器的值到底该被哪个进程赋值

Error (10028): Can't resolve multiple constant drivers for net "signal_out" . For this reasons I try to insert all signals in one process, in this manner: process(signal_1, signal_2) begin if rising_edge(signal_1) or falling_edge(signal_1) then if something then signal_out <= '0...
the united states department of energy says. in areas where there are not enough lines to transmit electricity from the most efficient generating stations, utilities must find other sources. sometimes they have to buy from costlier power plants nearby, like drivers forced by highway bottlenecks onto...
but this would not synthesize as it viewed inOutBitn as having multiple drivers. Is there anything I can do to get this to synthesize? I know I can just declare my top-level inout port to be a std_logic_vector, but that is sub-optimal as we have a a well defined port-labeling ...
Meanwhile, other opto-electronic devices, such as the electrical drivers and modulators which work at high baud rates, can further reduce the system bandwidth. The system performance is seriously degraded by Inter-Symbol Interference (ISI), noise and inter-channel crosstalk enhancement due to the ...
In that case, the voltage of the analog node will depend entirely on the drivers in the analog circuit. See Figure 9 for a visual representation. Figure 9 Verilog-To-Transistor-Level Strength Conversion Transistor Level-to-Verilog Conversion Transistor-level resistance value is converted to the ...
I'm trying to write a VHDL testbench for ModelSim (switching from using the quartus 9.1 waveform editor) I feel like this is a pretty simple procedure... everything compiles, no warnings, but when I run the simulation, my signals don't change at all, they just ha...
VHDL. this signal is connected to multiple drivers. Help me please TODAY!!!I have main entity.I also have RAM 16*8bit component. Which has port (address, accessing indicator, reading indicator, writing indicator, IN/OUT DATA)So, first 16 clock cycles I need to read main's entity input...
