I need to run power analysis . so i need .vcd file. So can any ione say how to generate a .vcd file. I have model sim, Xilix, RC compiler , SoC Encpunter 8.1 . From these can i generate a .vcd file if so let me know the steps pla.. i have lib, lef , sdc, sdf.etc file swith me.. plz help me.. i need some steps....i asked in digital forum they requested me to post here... i.e in this forum...
Please read the following link
Seems like a reasonable explanation and probably better than anything I can provide since I do not have access to modelsim. Once you have the vcd file you can use it across the rest of the tools you mention. It is probably best to read the vcd into RC and generate a TCF to use for the rest of the tools. TCF runs faster in the end since it only contains the toggle activity
hope this helps,

I saw your url and it was different andi couldnt get ehat i need.. i need the whole procedure to generate a vcd file either from rtl compiler or xilinx or modelsim... please help me this issue ir related to my thesis ....
In reply to Music:
I realize that it is frustrating when everyone tells you to look somewhere else. But I can't tell you how to create a VCD file here if you are using Modelsim to simulation your netlist. This is a Cadence user's forum. If you were using Cadence's NC-Verilog or NCVHDL, you would create a VCD file using a TCL command on the simulator's interface.
database -open -vcd testpatterns.vcd probe -all -depth all
But I wouldn't know what commands you would use in Modelsim, since it is produced by another company.
In reply to TAM1:
As TAM1 mentioned, your simulator is the tool responsible for generating the VCD, and in your case it is not one produced by Cadence or that I am familiar with all its switches and options. I tried forwarding a link showing how this is done using modelsim but it sounds like that link may have been missing some of the information you need based on your response. I suggest you contact your Mentor AE or Mentor forum for help on modelsim. As per the other tools, you have everything you need and all of them will simply read the VCD file generated with modelsim. The documentation has detailed information on how to do that.
TAM1, i know it's been a while for this thread but i'm hoping this will make it to you. I'm using Spectre from within Cadence and want to write out a .vcd file. Is this possible? I saw your tcl commands above, but i'm not even sure where i would input these and i'm not certain that Spectre has a tcl interface.
In reply to geezmaneti:
Yes. You simply need to create a TCL file with the commands I mentioned above.
Now, if you were running the simulator yourself from the command line, you would use an option like "-input myfile.tcl" to tell the simulator to read and execute that script file.
I'm afraid that I don't know how Spectre interacts with the simulator, but I imagine there is a field or option that you can set that would pass that TCL script to the simulator. You'll have to get info about that from the docs or someone else who knows Spectre.
