4. I am getting Out Of Memory

For Windows: Try the following command in Terminal (DOS shell) and then run the tool:

set JAVA_FLAGS=

For Unix/Linux:

unsetenv JAVA_FLAGS or setenv JAVA_FLAGS ""

Alternative Solution:

If you get "Error occurred during initialization of VM - Could not reserve enough space for object heap", open the setup_env.* file and reduce the MAXMEM variable value. Alternatively:

setenv MAXMEM 1024
setenv JAVA_FLAGS " -ms5m -Xmx${MAXMEM}m "

If out-of-memory occurs during execution, increase MAXMEM value on a 64-bit machine:

setenv MAXMEM 6144
setenv JAVA_FLAGS " -ms5m -Xmx${MAXMEM}m "

5. How can I download the latest library (designplayer.jar)?

Click here to download the latest designplayer library.

6. Will the tool work if I just download the latest designplayer.jar file?

Yes, it should work. If you face any problem, send an email to help@edautils.com

7. The DesignPlayer GUI is not opening - it's giving an error

This problem may arise if Java is not in your path. Run 'java' in the terminal to check.

Fix: Copy JRE or install appropriate JRE for your platform inside the $EDAUTILS_ROOT/bin directory. Make sure the directory name is 'jre' (mandatory).

8. I want to cleanup the cache or hidden data so it starts fresh. The GUI got messed/corrupted.

Execute the following command:

\rm -rf $EDAUTILS_ROOT/bin/configuration/org.eclipse.*

Also remove the directory named .edautils in your home area:

Windows: C:\Users\<your login username>\.edautils

Linux: $HOME/.edautils

9. How can I generate testbench for SystemVerilog module with multidimensional ports and interfaces?

First generate a wrapper using genwrapperverilog tool, then pass the wrapper to the Verilog testbench generator.

10. How can I generate VHDL testbench for entity with multidimensional arrays or record type ports?

First generate a wrapper using genwrappervhdl tool, then pass the generated wrapper entity to the VHDL testbench generator.

11. How to set environment variables and start DesignPlayer GUI in Linux?

14. How can I set EDAUTILS_LICENSE_FILE to run the tool(s)?

Save the license in EDAUTILS_ROOT directory, HOME directory, or run directory.

For Linux:

setenv EDAUTILS_LICENSE_FILE /pkg/tools/DesignPlayer-linux.x86_64/26NOV2016/edautils.lic

For Windows: If problems persist, remove EDAUTILS_LICENSE_FILE setting and save the license file in HOME directory (C:\Users\<YourName>) and EDAUTILS_ROOT.

Alternative: Set EDAUTILS_LICENSE_KEY instead (do not set both simultaneously).

15. How to fix OutOfMemoryError: PermGen space in EDAUtils GUI?

Open bin/DesignPlayer.ini or bin/UPFEditor.ini and increase the memory value:

-XX:MaxPermSize=2048M

(Increase from 1024 to 2048 or more as needed)
