Problem Title:
VERILOG-XL:  Attempt made to connect to an existing Verilog
Environment,connection not accepted



Problem Description:
When you invoke the Verilog-XL Environment, it may fail with, "Attempt
made to connect to an existing Verilog Environment, connection not
accepted - exiting."

This message is usually seen when you are using the Verilog-XL Environment (as o
pposed to standalone Verilog-XL).  It indicates that the interprocess
communication manager "cman" is still running.


Solution 1:

Check to see whether the "cman" (Communications Manager)
process is still running after you quit Verilog-XL :

  ps -auxwww | grep cman

This command may give you output that looks something like this:

  username  19046  0.0	1.2  308  720 ?  S    Jun 11  0:00 cman
	      ^
	      process ID

In this case the process ID is 19046.  Kill it with the following command:

   kill -9 19046

The Communications Manager manages the interprocess
communication between Verilog-XL and Simwave waveform
viewer.  This problem usually occurs if you do not
do a clean exit from the Verilog GUI through the Quit
entry in the File menu.
