Hi everybody

I am stuck with debugging of my vhdl code in ISim (ISE 8.2i). In recent 
ISE versions, ISim allows track changes in a signal, state transitions 
for instance. But it is not available in old version. So how to tackle 
this situation?

Regards

Dear Jack and Mr Z

Thank for your suggestions. Actually I am working on xcs200 chip. I am 
finding difficulty in tracing signal changes as I need to move bar line 
over signal after a lot of zooming in. So modelsim gives such or 
alternative functionality to trace signal changes? Or any other 
alternatives ...
