you need to read the datasheet first what is the output format. Basically, it is in binary, either in serial or parallel form. To display on seven segment display, you need to convert the format from binary to decimal form, use the circuit such as binary to decimal (bcd) conversion circuit. You can implement it with FPGA. Search the web for vhdl
Hi there, please advice on how is the most effective way to change 8-bits binary no. to bcd by using vhdl. thank you.
Here is verilog code for 16 bit bcd up counter translate this to vhdl! Hope this helps! module bcd_count ( // Outputs count, // Inputs clk, reset_n ); input clk, reset_n; output count; reg count; always @(posedge clk or negedge reset_n) begin if (!reset_n) begin count <=
hi, is there someone who knows where to find or who has some verilog/vhdl implementations of a (iterative) bcd multiplier ? thanks, avt
Hello to all, I?m newbie in vhdl programming on FPGA. I need help from all of you out there. Right now I try to write a code for 2-digit bcd down Counter, LCD display message and synchronization between both of them. For 2-digit bcd down counter, here?s my code library IEEE; use IEEE.std_logic_1164.all; use IEEE.std_logic_arith.all;
hi I need how design code vhdl for bcd adder 4 digit(16 bit) ?
Do you mean 16-bit bcd adder??? If yes see the link below... Its in verilog you can convert it into vhdl ..
hmm....can you xplain it more beter? im having problem on making a vhdl code, coz i dont know the structure.... can you post the structure of it?/ thnx in advance In terms of structure, it's up to the coder. There are many ways to do it. But I feel as though you are seeking HDl code to solve your problem. You can fin
hi i have to perform real num addition. i will use the single precision format. can i give the input as a real num for ex:4.5.. is this possible in vhdl can any one help me how to convert real num into binary.. using vhdl i am not getting how to proceed
I have written a structural code vhdl and tried to compile it. Code: library ieee; use ieee.std_logic_1164.all; use ieee.std_logic_unsigned.all; entity mux_8X8 is port(A,B: in std_logic_vector(7 downto 0); start, reset, clk: in std_logic; result: buffer std_logic_vector(15 downto 0); leds: out std_logic_vector(1 to 7); done_
Hi, I need to implement a simple vhdl frequency counter for a school project. Must be 4 multiplexed digits. (the FPGA as few macrocells). I know how to implement the counter and the bcd to seven segment. is the multiplexing and puting things togheter that i need help. Can anyone point me to an example? Must be very simple. Thank you in
Hello - I am somewhat new to vhdl, but I have some past experience with discrete digital design. I would like to take a bcd number that is in the std_logic_vector format and convert it into ieee single float format in order to use the number as an input to the Xilinx Floating Point IP Core. I am starting in bcd because it was (...)
I'm from Brazil, but I think I can help you. You can describe a frequency divider for the 50 Mhz oscilator on the board. To download a vhdl code in the FPGA, you can read the ISE Quick Start Tutorial that you can find here: ∫Good Luck.dx

Hi I have a vhdl code counter that counts in binary from 6 to 88 then it rolls over to count down from 88 to 6. Now i want to do the same counter but instead of counting in binary i need it to count in bcd. can i show the count values in quartus in bcd? if not please any help how can i do that? thank u in advance.
Whats wrong with fixed point packages? there is a Xilinx version here: vhdl-2008 Support library But whats wrong with this code? temp0 := resize(Input1, temp0'length) * 2**12; temp0 := temp0 * 3300; output <= temp0(23 downto 12);
What's you particularly question? I see, that you have been able to copy the popular "double dabble" code from the internet. (Reference in ) As far as I see, it's a syntactically correct vhdl function. I assume, it will serve it's purpose. P.S.: In addition, you would want to add a standard package
I am trying to write the vhdl code for a Timing Genarator Chip : in the vhdl code i have to incorporate a code for the 16 Bit bcd(Binary Coded Decimal) Counter i.e. 4 Decades , i tried a lot but unable to figure it out how to get it working... as the 16 bit bcd counter can count from 0 to 9999 ,for the first 9 clock pulses (...)
Hi, Define your input and output seperately, thenn define a new variable using inputs by concatenation (the operator &) here is one
Hi, I need to develop a vhdl code for 9 bit binary to bcd number. I searched in internet and find code for converting 8 bit and 10 bit numbers Can anyone help me in writing the code for this 9 bit binary number
Hey Barry; I thought you could interpret it should be in vhdl... As I have posted it under FPGA thread..... As by far people program it in vhdl... well its FPGA...
I am not familiar with ASIC design flow, maybe somebody else can give some valuable comments.... For FPGA design, what I have used synthesis tools(only to synthesis vhdl code): Synplicity Synplify > Synopsys FPGA Compiler II > Mentor Leonardo Exemplar It is only my personal opinion...
Can someone give me links to documentation and foundries proposing bcd-processes (biploar/cmos/dmos)?

IMHO, I think Verilog will probably become increasingly dominant in the future. Realistically though, vhdl is here to stay for a long time. This means several things. 1) You still need to own and know how to use vhdl tools. 2) You still need to know vhdl
