How to print a state flow graph for a state machine using Xi

[Weng Tianxiang]

Hi,
Can you help explain a method to print a state flow graph for any state
machine design written in VHDL using either Xilinx ISE or ModelSim
software?

If neither has the ability of doing the function, what else software
can do it?

Thank you.

Altera Quartus has such a viewer.

Well, I did a state machine in ISE some time ago, and as far as I can

remeber, it was a matter of chosing "print" from some meny. I dont recall
having any trouble with that at all.

Another thing is that I write my own state machines from now on. In VHDL.
Thats not difficult at all. And the code generated from ISE is not *that*
good, when it comes to human readability.

Hi Jan,
What I want is not let Xilinx ISE to generate a state machine code for
me, but I want ISE to print a flow graph of a state machine written in
VHDL.

Thank you.
