I would really appreciate your help. I wrote the following testbench code to test my 6th order FIR filter. It worked perfectly for my behavioral code, but when I try to use it after synthesis for my structural gate-level netlist, I get this error: ERROR:HDLCompiler:1728 - "/home/..." Line 24: Type error near xin ; current type signed; e
Hi. I'm trying to import vhdl source code into Verdi. The source code included user-defined-library file like this library ieee, ZOTLIB ; use ieee.numeric_bit.all ; use ZOTLIB.COMPONENT ; ... The error messsage is like this Can not find library. How can I import library?
Unlike Verilog $readmemb(), there's no standard method to import ROM data to design tools. Some tools understand vhdl files for inferred ROM, some can import hex files for vendor ROM macros. Generating a *.VHD file with a constant array is probably the most portable method.
Maybe you can import vhdl/verilog netlist (synthesized by DC or other tools) directly into virtuoso environment. Then a new schematic will be generated and can be used to do further simulation in ADE. Regards,
Hi, I'm looking for a way to convert a Behavorial description (in vhdl or VERILOG) into a (H)SPICE netlist. I did it in the past with tools from Cadence, but in my current situation I can only use tools from Synopsys. I've tried to look into Design Compiler / Nanosim but I couldn't find anyway of doing that. Is there any other software to do
Information in this page suggests that a function declaration is optional... . The link doesn't talk about packages at all, just functions in general. I see that it doesn't fail a parsing check... Did you also try to import the function in your design? I presu
Ususally, circuits are written in HDL, and often in behavioural form. There is no way to input a K map, just the circuit diagram (which people dont use much, as it cannot be simulated directly). It is much better to use an HDL (vhdl or Verilog).
Alternatively you can build your ISE projects from a Makefile. Then add a rule to update the vhdl file with date & time in it. Essentially it's the same mechanism as that tcl example ... generate a vhdl file with datetime in it.
c <= ('a(3)'&a) + ('b(3)'&b);--to make sign extension. You can also write c <= resize(a,5) + resize(b,5); or even shorter c <= resize(a,5) + b; What I'm doing is because vhdl imposes that the LHS to the equal sign of addition is the same size as the RHS' operands. Will this concatenated bit be r
You will have to existing standard cell library to which you vhdl/verilog code synthesizes to. Once you import the gate level netlist into cadence it needs to map to the actual gate which should exist in the cadence library(if you have one). Once you get the library, then you dump the netlist and layout from the standard cell library. Usually peopl
i have a vhdl code ...and we have standard cell in cadence in the front end. How can i import vhdl CODE into cadence and link it with standard cells and simulate it? Pl Help
The question refers to the specific features of your design compiler. In constrast to Verilog, where $readmemb and $readmemh are widely supported by synthesis tools, only some compilers support text_io functions for data import. Some have vendor specific data formats to import constant data to ROM blocks. I expect, that your design compiler
Hi, is there a way to simulate a vhdl project created in quartus with ISIM of xilinx? I can't compile it in xilinx because it uses pll and other specific functions of altera. Thanks
Hello,I want to import an array (1 x n) to my vhdl code,every element of array is 5-bit.I know I should be use it in serial but I dont know how define input "std_logic or std_logic_vector(4 downto 0)?
I guess, the problem is missing knowledge of the vhdl textio package. Generally ASCII formatted data files are a straightforward way to read in stimulation data. You'll read e.g. one line for each clock cycle in your testbench, and decode one or multiple values and assign it to the stimulus vector. The testbench scans the file line by line and

I think you are asking for For vhdl the procedure is the same but you select the vhdl folder and files.
Does Modelsim support use of fixed point? It's no Modelsim problem, the libraries are just vhdl code. Apparently you didn't import the libraries to the simulation project. The altera simulator can only do post place and route simulation. Not quite right. The internal Quartus simulator (available up to V9.1) suppor
I import a vhd file in candece like following: Open icfb. Go to file choose import and then vhdl. Under the file name browser in the vhdlin form go and select the inv vhdl file hit the Add button on the right hand side of the browser window. In the Target Library Name field (...)
I have a synthesised vhdl file with TSMC 180 nm library using Synopsys Design Vision. Now,I want to have the schematic using Cadence Virtuoso.How to do that ?
hello. if i have my own independent vhdl file which i want to import as an ip in my xps project then how can i use GPIOs on the virtex II pro board to talk to my ip?? if i have a multiplier with 2 input ports and a single output port, then how can i send data to these ports using GPIOs??
However the manual suggests that vhdl user can create Verilog wrapper to cover vhdl code before import to system. Can anyone please give me an example of Verilog wrapper code? Hi both *.vhd and *.v files are in attachment. Below code is Verilog wrapper to cover vhdl code of simple up counter // VerilogWraper_upc
Depends on the tool you use. If you use Questa, yes, use: vcom -mixedsvvh and then the data types, constants declared in vhdl are visible in SV. There are some restrictions as well, read the user guide. Other tools may not support this, a WA will be to rewrite them in SV (can potentially use a script). HTH Ajeetha, CVC
Hi all, I met a problem. In vhdl file, there are: library unisim; use.unisim.vcomponent.all; When import this file into debussy, error occurs. Debussy can not find unisim lib. So I want the solution, can anyone help me:) Thank u very much! BR weiqi
Hi, There 2 packages in my design, each of them defined a function with exactly the same prototype. How can I specify which one I want to call in my design?
I HAVEN'T BEEN USING THIS XILINX TOOL for quite some time and i decided to re-learn it with version 10 .And wow HOW MUCH THIS TOOL has got sofisticated. There is so much posibilities to design complex systems . I'm trying to completly design software defied radio and import some of the vhdl code to M black boxes . i'm having so much FUN .That all
hi guys.. i need to know how to generate vhdl coding from graphical design in Maxplus2.. i have drwn small simple circuit adder in graphical type, so i wan vhdl codine of it. thanks in advance..
I have synthesize vhdl codes and netlist is i want to import the vhdl(after optimization) of the netlist from cadence so that i start with my physical design. But somehow there was a problem with import and i received an error when i was importing. the error is: duluth: *F,24: logical (...)
Hi, Isn't it redundant from vhdl point of view? But it's import from a synthesis point of view since if the "when others => null;" statement is missing this can lead the synthesizer to infer latches. An RTL sanity check tool like spyglass will report a warning for this type of omission. Yours, Said.
Thanks for the reply. The test bench is using vhdl. I am using vhdl to implement my design. Regards, Dhawal
Hi, I assume you mean a RTL-> GDSII flow. In that case you need Modelsim to write your code in vhdl, for synthesis you can use Synopsys tools which will map the libraries according to the process that you are going to use for the chip tapeout. After Synthesis the tool will generate a .v file which you will import in a Place and Route Tool such a
Hello, Does anyone know how to convert a vhdl code to schematic in Quartus II ? It might be a simple process but I can't seem to find my way about it. Thanks.
hi evrey body i want to transfer my vhdl code trough leonardo to l-edit (transistor level) but because of the libraries in the leonardo have not any .TDB library in the l-edit i cant transfer my design if you have the laibrary that have (.SYN) and (.TDB) please upload that and please guid me how to add (.SYN) library to leonardo(the statement t
1. Do you have complete Debussy license? or just nWave license? 2. Please check if you specify topModule, source files and library. To invoke Debussy by command : debussy Some options : - vhdl | verilog : specify language type for import design from source (verilog by default) - top : specify top
Hi, Does anyone know how to import the EDN/NGC netlist file to a vhdl project in Xilinx ISE tool in order to reduce design time? I used to use this method in Altera with VQM netlist files with LogicLock feature. But I did not find any similar way to do that in Xilinx ISE tool. Could anyone give me some suggestion? Thnks
Does Cadence support vhdl-AMS?
If your A/D SFDR is generated by a Simulink model the best way is to write the result in a Matlab workspace and then measure via FFT the SFDR. You can read asci in Dolphin Smash and plot the FFT. If your model is a vhdl-AMS or Spice generate with Smash the best way is to write asci and import in Matlab. All existing Spice's have very limited bac
I use ncsim simulate. thanks. avoid using variables in your vhdl design. VCD file seemed cannot record them
hi, does the ".syn format files"of leonardo spectrum equivalent to .lib files that contain timing information abt cells?if so is it possible to convert to .syn files to vhdl files so that i can import these vhdl libraries and do backannotation. if not using which files does loenardo give the sdf file output?
Is it possible to import HDL (vhdl or Verilog) into ADS? How about C or C++ codes? What i saw in ADS is HDL generation from schematic or design. But i could not find anything about importing HDL (digital design) or C (high level language) codes from outside. Any helps will be appreciated. Thanks in advance, KH
Hi! Can anyone take a look at my project and help me with it. I am trying to import my vhdl and Verilog code via BlackBox and simulate it. but it doesn't work and i don't know why.. :( Anyway I assume that I am missing something.... 10x bart
Since ispLever Base 4.1 doesn't support mixed language designs.. How can I incorporate a vhdl CPU core for example into a Verilog design?
Hi, I am new to Xilinx tools, I was wondering if I have a simple vhdl entity that I'd like to use/test in a edk project a long with a process, how do I import(?) it to the EDK? I'd appreciate if you breifly describe the procedure. Thanks, Mo.
uses command tools: vericom & vhdlcom, cpmille your source code into libraries, then load the libraries into debussy
Hi, Does any one know how to import verilog & vhdl mixed-language design with Debussy? How to edit *.f design list file? my debussy version is 5.2v9, I think it should support this feature. Thanks ahead!
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 that to a vhdl program and dump the whole f
