Hi, I have studied about BPSK demodulation theoratically. However, I am having troubles with bridging it with vhdl representation. I tried to search the internet but to no avail. The issue that I am facing is that after all the search on the net I did not get the BPSK Demodulator's block diagram so that I could start the (...)
protel dxp 2004 does just that... i had written vhdl code and converted its i/p and o/p port to the block.
Hi, I want a block diagram for the implementation of WCDMA in VLSI using vhdl. Please help me. Thank you!
Hi everybody, does anybody knows how to convert a palasm file into vhdl, or block diagram design? i know how to convert manually, but the result its wrong, and i´m tired of checking the block diagram. So i need to try to convert automatically. Thanks a lot Breno
Hello I think you can have a try for the fpga advantage of Mentor or the active-hdl of aldec. These tools can import verilog or vhdl source and translate them to schematic. And you can have a try for the novas.
Hello to all, I'm planning to develop a simple controller for the following anyone can help with vhdl, verilog, or simply supplying a block diagram or a reference book where to learn such stuff? I don't have any idea where to start.... :cry: Thanks a lot !
You can use the following function to convert std_logic_vector to integer. signal a : std_logic_vector(3 downto 0); signal b : integer:=0; b <= conv_integer(a); Now you can use this integer to access the memory. --vipin
hi frnds,I m thinking to implement a USB port in my project in either VERILOG or vhdl........... can any1 please provide me d exact block diagram of USB2.0 PORT............. its very urgent...plz,if u found mail to
A sensor is used to detect the number of bottles on the conveyor. The user can set any number of bottles he wants to detect on inputs: P4P3P2P1P0. Design a system such that when the reference number is reached, a led turns on and the counts stops at the reference number. Show the number of bottles detected on 5 Leds and the value of the reference o
You may also try searching the internet (i.e. google) for University presentations about "synthesizable vhdl constructs". There you will see differencies between signals and variables and many other things. A post-synthesis schematic can be very helpful as stated above.
Could someone kindly provide the vhdl code of the implement of ADPLL, such as ECPD, K-counter, ID counter? Thanks in advance!

Dear all, I need some vhdl sample codes for the common communication systems modulators and demodulators .. such as QPSK, OQPSK, BFSK, ... and so on.. Can someone tell me where from? Or upload some? Thanks , Ahmad,
It can generate an RTL schematic and you can go look at how the design is implemented. Another tool which maybe of interest is HDL Ease, it can take vhdl and create block diagrams of a design. - Jayson

how're you guys? I just wanna get some help from you, I'm actually good at digital design I mean using the block diagram but as everyone knows, we should be good at vhdl in order to be good designers. Moreover, I'm goona take a course related to vhdl designing in a year, however, I wanna improve myself in this (...)

Fresh out of backprop code. But if you find any (vhdl or verilog), please do share your findings here. :) verilog codes can be goggled but not vhdl any findings are highly appreciated.
Hi, In libero, I wrote a verilog code and generated vhdl netlist of the code and connected vhdl netlist to another vhdl project. However, synplify gives the following error message after long compilation . @E: CD708 :"C:\AAAAA\XXXXX.vhd":82:22:82:35|Not a concurrent statement. does anybody have an idea..?

can any one help me to write a vhdl code for backpropagation algorithm in neural networks with block diagram
In the above block diagram, we are using Galois arithmetic to form an encoder. here the field generator polynomial(p(x)) and code generator polynomial(g(x))are taken as follows, We have used p(x)= x4+x+1 and g(x)=(x+1)(x+2)(x+4)(x+8) = x^4+15x^3+3x^2+x+12 The message polynomial is taken as: M(x) = x^14 +2x^13 +3x^12 +4x^11 +5x^10 +6x^9 +7x^
I'm working on the implementation of reed Solomon Encoder in vhdl. Can you tell me how this block works? The encoder is based on Galois field arithmetic where the 4 LUT blocks are multiplied with 12,1,3,15. We are giving input as 1 to 15(4 bit binary) to the multiplexer. The control line is given as 1 at first. it is changed to 0 after (...)
