I just purchased an FPGA and I am learning Verilog but I have run into a few confusions, most of them regarding the clock. My first question is, how does sequential logic work? Are the assignments ...
I want to know if we assign something to a register ( or do anything else ) in a specific clock cycle, this assignment is performed in the current clock cycle or the next cycle? (Setting: Xilinx , ...
I have a top module ,everything it does is get inputs and outputs,define some wires and instantiate other modules.Every such module has a clock input. I am wondering if I should define a clock in the ...
I have a module m(in1,in2,in3,in4,out1,out2); I need to implement it in such a way that in each positive clock edge : if ...
I have a VHDL memory core which requires me to multiplex between two clocks. The Write clock operates at 200 Mhz and Read clock operates at 100 Mhz. I think this can be done using ...
My HDL compiler (Quartus II) generates timing reports. In it, the nodes have "clock skew" column. The only definition of clock skew I found is in the TimeQuest documentation (see page 7-24): To ...
I am getting my hands on Verilog and FPGA programming. So I wrote a simple module that handles two inputs - button signal and a clock. Initially, it lights up two LEDs and when the user presses and ...
I am a novice in digital design and are learning things using "Advanced Digital Design with the Verilog HDL" along with a Spartan-6 LX9 board by Xilinx. So far I have managed to blink few leds on the ...
