It involves the design, VHDL coding, The results reveal the versatility of implementing dedicated circuitry. Key words: FPGA, VHDL, PWM, Reconfigurable.

In many applications we don’t need a PWM which is so fast. In that case, the clock frequency is first passed through a divider, and the divider output is used to generate the PWM. VHDL code for PWM controll. This code works with any FPGA chip. Without any change, it works with 50MHz, but this can be change to work with less or more clock rate. There is a macro file with the simulation a in the path..\simulation. I just started to program in VHDL using Xilinx (ISE 14.7).

PWM: Pulse-width modulation (Sv: Pulsbreddsmodulering).

When the counter value is less than the PWM- width value the PWM output is high, else is low. So let' see an&nb end PWM; architecture Behavioral of PWM is signal tmp : std_logic_vector(3 downto 0); signal up_down : std_logic; ERROR:Xst:2358 - "C:/Users/Mazen/ Documents/VHDL Projects/First/PWM/PWM.vhd" line 45: Operands of a 18 Sep 2016 If the pulses are fast enough compared to the response time of the system, a PWM is equivalent to a varying analog signal, whose amplitude is proportional to the duty cycle. The maximum output frequency of the PWM output&n 27 Mar 2019 How to generate a high-frequency PWM signal from the FPGA (Zybo) with the full VHDL code and Vivado.
