up to my knowledge .. u still can't get a good design if it's automatically generated .. good designs need to be designed by a designer .. not only entering coefficients to a system level tool (like matlab) and press a button to get a corresponding vhdl .. and though this may work sometime .. it's not recommended for (...)
what is the difference between labview and vhdl vhdl is programming language for hardware say FPGA/ASIC. where as Labview is higher lever language to design complete system. Labview project may contain some block with vhdl code also. It can be compared with matlab for instance.

Hi, I am a design engineer working on VLSI and vhdl.I am interested in learning matlab as it will be useful in vhdl programming. Is there any particular area that i have to concentrate in matlab or should i learn complete matlab. I heard that simulink and system generator (...)
Hello everyone, I need to run the following Mathworks tutorial. Simulink and ModelSim Tutorial :: Linking Simulink to ModelSim (Link for ModelSim) The tutorial is simple. It simulates an inverter written in vhdl and compiled by modelsim, and the test patterns are generated us
I have a data file of a signal I captured on my oscilloscope, the data contains time and voltage for each measurement. Is it possible to import this text file into matlab and create a DSP model that uses the data file as input and runs a filter algorithm on it and then somehow using SystemGenerator export (...)
The System Generator for DSP tool is one of the industry's most popular DSP design tools for FPGAs. It automatically translates DSP systems developed using matlab? and Simulink? from The MathWorks into highly optimized vhdl and IP cores for Xilinx? FPGAs. Designers can design and simulate a system using (...)
how can i convert modelsim waveform data into matlab, and simulate it with matlab? another question is how can i convert decimal fraction into binary,my purpose is multiple two decimal fraction and output it finally with fpga.
you can generate white noise with matlab, and then transform it binary data, such as symbol function. you can store these data and regard it white noise.
Well DSP requires a high level modeling usually done with matlab an ideal solution is ACCELFPGA wich is basically a matlab language compiler . Otherwise .there are plenty of libraries of cores they produce vhdl most of the times and VERILOG too the HDL code produced by COREGENERATOR,SYSTEM GENERATOR .SYSTEMVIEW (...)
I implemented the gabor transform in matlab and there were satisfactory results compared to the DCT.I tried implementin them in vhdl and the effort was DSP implementation the only way to realise gabor or how can i implement in vhdl? The problem i faced was in implementing the 4D ffts.
Hi guys, I have been quite interested in matlab. Do we really need it as an ASIC designer? and how could it be used in ASIC design? digital or analog. Any advice is appreciated. Thanks in advance!
Look here , for example Interactive simulation of a PID with autotuning is here .
Hi Yes, There are at least three different ways 1. Accelchip +matlab 2. Xilinx systemgenerator +matlab 3. Altera Quartus +matlab tnx
Dear friends is there any tool to convert automatically from matlab files(m file)into vhdl file(vhd). thanx for help
Hello these are matlab codes for RS
Your question is a bit unclear. matlab mabe pluged into your vhdl simulator. You can eother use some commertial library that generates vhdl out of matlab, or use simulator and matlab C API to connect both. Good luck!
Xilinx,Leonardo spectrum can generate schematics for vhdl code. Even you can write the code in matlab and system generator will generate vhdl code for the written code. from that you can generate schematics. I hope i am clear to you.
What about using Digital Filter Analyzer (DFA) from It can generate vhdl for simulated filter design. Coefficients are stored in a ROM table and intermediate multiplication results are stored in RAM block.. then summed. I had a question for anyone who had used it before. How is it compared to matlab R14 filter design (...)

matlab based, vhdl based projects etc will help you.
Dear Ahmad Open matlab 7.8 , R2009a , and you will find a demo in simulink HDL coder describing an LMS filter , it is written in embedded matlab and convertable to vhdl. see the demo help for more details , feel free to ask salam
Good day everyone. I'm having this project right now. I'm going to have an ADC simulation using matlab and honestly, I don't have any idea how to start it. Below are the specifications: Input Frequency: 21 KHz Transition Band (Fstart to Fstop) : 0.3 to 0.4 Input Signal Voltage: 2.5 V Ripple Voltage: 0.02 V Main Clock Frequency: (...)
is there any way to use the results of the simulation made with vhdl(-ams) codes in matlab???
Hope this helps -- Amr Ali
hello all,,, I heard that is possible to use matlab to generate a vector file and use this vector file in testbench module for testing an FPGA module,,, is that achievable and how to do that,,, thank you in advance :-)
Hi ppl I'm new in vhdl and I want to convert the following equation is written in matlab to vhdl x=*5 thanks in advance
Hi all, Well I have to design a base index generator. When I say base index it is nothing but indexing the output of a binary counter. Well let me explain it clearly. We have a 13-bit binary counter who outputs are quoting to 4096 locations on a RAM and we have 13 such stages which is like the counter should count to 4K for 13 stages. Now we
Hello every body I am doing a project on FPGA based acoustic noise cancellation systems. I did matlab and vhdl coding for this.Now I want to implement it on FPGA spartan3 board I would be very much grateful to you if you can provide me guideline for this thanks
I don't use Verilog for testbenches, but in vhdl testbenches , it's easy to read matlab generated files with general file I/O commands. I guess, it should work with Verilog $fread as well. It's particularly useful, when you want to supply a waveform to a signal processing algorithm, one sample per clock cycle. But you should be also able to (...)
Is it possible to convert all the matlab files to vhdl/verilog file using any inbuilt functions in matlab??
i need help that i have created a .bin file in matlab and i want to read it it vhdl...!! kindly help me out !! thanks alot !!

Hi all, can any one please solve me this error when a making "socket" connection between matlab and simulink. I have the following error Error reported by S-function 'shdlcosim' in 'bi_dwa/HDL Cosimulation/S-Function': Failed to connect to server. Make sure the loaded HDL simulator library is using shared memory. thanks a lot
Hi suga I can possibly convert your design from matlab to vhdl. First I will hand code an equivalent C model and then automatically generate vhdl with my own high-level synthesis tool. PM me if you are interested in discussing this matter further. Best regards, the_penetrator ---------- Post added at (...)
If your purpose is just generating vhdl code, matlab HDL Coder is suitable. However, it generates lots of files, and most of time result is not suitable for FPGA bitstream generation. SystemGenerator is nice tool, it allows you to design your system with IPCores like designing in Simulink. If you knew IP CoreGen, SystemGenerator allows you (...)
I need to import data generated from matlab into vhdl program and then execute and get results exported into matlab for further analysis. how can I do it?
thanks for your answering TrickyDicky. I compiled my counter.vhdl code by Quartus Altera . then I exported it to counter.vhdl Testbench, (counter.vht).then I started matlab and change the directory into the counter.vhdl testbench directory and I entered "vsim('socketsimulink', 4449)" (...)
hi all, I want to implement Sgma-Delta ADC on FPGA altera board using verilog code; I want to design my circuit using matlab simulink and then use matlab HDL coder to get verilog code ; but i dont know how to design my circuit in matlab and HOW to start with matlab; any body have useful (...)
I would use neither. I dont know labview, but matlab and simulink are just high level modelling environments and pretty poor FPGA development tools. The HDL code they generate is sub optimal. Its fine if you dont mind wasting a load of space in your FPGA, but to get the most out of it you need to hand code your design, which (...)
This is not really a vhdl problem, more of an algorithm problem. You probably need to model the system in something like matlab and see what kind of error you can cope with.
