Creating custom *do files with Xilinx ISE & Modelsim

[nanisan]

Hello

I have created a custom *do script file to use for the ModelSim behavioral simulation instead of the automatic <file_name>.fdo one.

To create the file I have followed the steps outlined on Xilinx page below:


**broken link removed**
-------------------------------------------------------------------------------------
To prevent Project Navigator from loading the default signals to the waveform window, you will need to create a custom DO file. Follow the steps below:
1. Copy the automatic DO file created by ISE and give it a new name. For instance, if you are running a behavioral simulation and your testbench is named "top_tb," make a copy of "top_tb.fdo" and rename it to "top_tb_custom.do".
2. Open the copy in a text editor.
3. Comment out the call to the ".udo" file:
## <testbench_name>.udo
4. Comment out the "add wave *" command:
## add wave *
5. After the "## add wave *" add a new line that calls the saved waveform settings:
do <wave_name>.do
6. Optionally, add the "log -r /*" command after the line from step 5 (see above for more information on log -r /*).
7. In Project Navigator, right-click the Simulate Process and select Properties.
8. Uncheck Use Automatic Do File.
9. Check "Use Custom Do File" and select the custom DO file that you created.
--------------------------------------------------------------------------------------


However when I try to run ModelSim from Xilinx, none of the commands in my custom *.do file seem to be recognized.

Can somebody give me an insight into what I am doing wrong or how to go about creating/using custom do file in general?

Thanks

hai,

U can make ur input as follows

vsim count -- entity name is count vsim is load command for modelsim
add waves *

force clk 0 0ms,1 33ms,0 66ms -r 66ms
force rst 1 0ms,0 50ms
force clk_en 0 0ms,1 100ms
run 2000ms -- time period to run

save the above file in ur project folder as "count_do.do" .
Then in simulation option uncheck the automatic do option and check the custom option.
