please help me to solve error - behavioural simlation ise9.1

[kalpana.aravind]

could not resolve instantiated unit

Hi All,

I am using ISE 9.1i free webpack and trying to do tutorial ISE8 on it.
While doing the behavioural simulation getting following errors.
I am using Xilinx ISE simulator, please if anybody tried withthis before please help me to solve this.

ERROR: HDLParsers:3482 - Could not resolve instantiated unit ten_cnt in Verilog module work/stopwatch in any library
ERROR:Simulator:198 - Failed when handling dependencies for module stopwatch_tb

Any suggestions welcome.
Thanks

Hi,

I have copied the stopwatch.v code here, as i could not attach the file.
If u find any modifications in this for the simulaion errors as i mentioned earlier please highlight to me.

stop watch xilinx ise 7.1

This error is because ISE cannot find the modules u have used in the top-level design. Make sure that the modules are present and included in the project and also that the module names match. This should resolve the error.
