I am receiving the following Error when running ISIM:
How can I debug this error?
You can use the "isim ptrace" command.
This command, when enabled, will assert to the transcript window the specific process ISim is currently working on.
Once you reach the iteration limit, check the last "visited" process.
This will help to indicate which process is causing the problem.
You can enable ptrace by typing "isim ptrace on" in the ISim Tcl console.
For more information, check out the "isim ptrace Overview and Syntax" section in ISE Help (http://www.xilinx.com/itp/xilinx10/isehelp/isehelp_start.htm)
*Most* of the time, iteration limits occur due to unlimited for loops in the testbench.
Review for loops and wait statements in your testbench.
