Hi friends, hop u r ok, I have a problem with this QPSK code : library IEEE; use IEEE.std_logic_1164.all; -- defines std_logic types use IEEE.STD_LOGIC_ARITH.all; use IEEE.STD_LOGIC_UNSIGNED.all; entity Sinus is port ( CLK : in STD_LOGIC; --INFA: in std_logic; -- --INFB: in std_logic; --OUTP: o
Hi all, I think this is a fairly trivial question for those experienced in verilog design, but I haven't been able to find any explicit answers I'm writing a module where I am calculating frequency of an incoming signal, by first counting the number of clock cycles between change state of incoming signals. The number of clock cycles is stored i
I have a rotary encoder write in VHDL but this code does not work in real cpld , output port led do not show any increase in number! library IEEE; use IEEE.STD_LOGIC_1164.ALL; use IEEE.STD_LOGIC_ARITH.ALL; use IEEE.STD_LOGIC_UNSIGNED.ALL; entity left_right_leds is Port ( led : out unsigned(7 downto 0);
hi, i would like to find out what is the max operating frequency for a counter module in the Lattice cpld/FPGA library ? which model has the fastest counter module available ?
lists schematic symbols of Xilinx Virtex and Spartan FPGA, cpld and other complex components for the OrCAD (R) schematic capture tools. Each symbol or family of symbols is provided in an .olb library. The list of components is constantly expanding. Large schematic symbols have multiple components with pins logically grouped by f
HI I have a coolrunner 2 development board. Dividing the clock was easy, I now have 90Hz clock, but the darn buttons just will not be debounced. I have the VHDL code to debounce a MAX FPGA, and the code makes sense, 4 bit shift registry. It compiles but just wont work. I need a help to debounce my push buttons in VHDL for this cpld. If any one co
hello guys i am a fresher in this field i wanted to learn about FPGA & cplds. i got book regarding FPGA and cpld. But it dosen't contain how to configur it .can any one help me regarding this. and also plz tell me the tools for that
I have not been able to find a library with any of the more recent Lattice cplds for Eagle anywhere on the Internet. Anyone have one or know hwere to get one?
