When running a simulation in verilog, it is possible for one to use $dumpfile to dump simulation data into a VCD file. This VCD file does not seem to be human comprehend-able. What tools exist to view the stored data in these files graphically? As far as I know they are to be viewed using some sort of waveform viewer. However, I am not aware of any
Hi, Which signals have you selected for monitoring? The following block selects all signals in the top of the design and down into module instance DUT0: initial begin $dumpfile("sim.vcd") $dumpvars(0,DUT0); end dumpvar syntax: $dumpvars(depth, intanceName) The file sim.vcd can be read my many waveform viewers. There is also
To read array from test bench use: initial $readmemh("data.txt",mem); In above case you read hex data from data.txt file to read memory data. You can use for loop to traverse through all the location. To write data to text file use: $dumpfile("data.txt"); Hope this helps
Dear Sir, I am simulating a multiplier in xilinx ise. i want to find dynamic power and plot it against time and frequency using xpower. But it shows 0 dynamic power. I used a clock to feed the inputs and generated a vcd file by the following codes in test bench; $dumpfile("vcdfile.VCD"); $dumpvars(0, tb_generator_v.uut); But often the
Dear Sirs, I am trying to find out dynamic power consumed by my multiplier. So i want to generate a vcd file. I am using the following codes in my verilog test fixture initial begin $dumpfile("invchn26.vcd"); // Change filename as appropriate. $dumpvars(0, generator); $dumpall; $dumpflush; end But vcd file remains empty. Sometimes
hi,i want to measure the power which includes dynamic power.i use xilinx/ise 11.1.although i put the files that xpower needs in the same folder.but the dynamic power is always 0. i generate the "myfile.vcd" by isim using these commands but it seems that xpower doesn't care of this file. vcd dumpfile myfile.vcd then vcd dumpvars -m /myfile r
`timescale 1ns/100ps module dump(); initial begin $dumpfile("/auto/Gigatron/auto_init/Gigatron/sim/tests/EgProc_TMerge_RxMet/Simple/vcs_run/Simple.vcd"); $dumpvars(0, board); #6000; $dumpon; $display("INFO: %0t: Dump started.", $time); #3000; $dumpoff; $display("INFO: %0t: Dump finished.", $time);
I do not know about the lsi_dumpports command/pli; so the following about the VCD dump tasks defined in the verilog specification may not be useful. A typical approach is as follow: 1) Create a VCD file $dumpfile(" 2) Specify variables (signals, ports, registers, etc.) to record (dump) $dumpvars(,
You can easily download them yourself using the free mplayer. Save the .ram file of the lecture you want to download, open it with some text editor and copy the rtsp url. Then use the following command mplayer -noframedrop -dumpfile filename.rm -dumpstream rtsp://url/to/file.rm -bandwidth xxxxxxxx Specify the bandwidth is in bps(bits per se
i produce vcd with modelsim by using the following code The design has been ungrouped in design analyzer and is in verilog format. initial begin $dumpfile("mullbin8.vcd"); $dumpvars(0,mullbin8); $dumpflush; end ---- I then use the saif file from the vcd with the following. current_design mullbin8 power_preserve_rtl_hier_names=true re
I am using VCS for System Verilog simulation..... I am new to VCS as well System Verilog.... How to observe the waveforms as we see in Verilog simulation using a dumpfile called *.VCD ....... I mean how to create .VCD kind of file in System Verilog using VCS....? I am using $vcdpluson in Verilog Simulation generate .VPD file
hi, Below is the verilog code for vcd dump: initial begin $dumpfile("file_name.vcd"); $dumpvars(n, DUT); //In ur case DUT is ha1 end For more info, u can check out in this book: Verilog? HDL: A Guide to Digital Design and Synthesis by Samir Palnitkar. To write to a text file, u need to use $fopen and $f
Checkout this! initial begin $dumpfile("top.vcd"); #100 $dumpvars(0,top); #100 $dumpoff; #100 $dumpall; $dumpon; end
I employ $vcdpluson in testbench, then VCS creates a default file(verilog.vpd). how to rename a new filename in VCS, could i employ $dumpfile ("filename")? Read their manul, quickly I see 2 options: 1. $vcdplusfile("filename.vpd") - inside your code 2. simv +vpdfile+filename.vpd in command line. There are lot
use: initial begin $dumpfile("./***.vcd"); $dumpvars; end you can also specify the signals and level of hierarchical in the $dumpvars. Then use debussy to translate vcd to fsdb or running power analysis or whatever you want with the vcd file VCD is usually much bigger than fsdb etc.
