Steven,
Have you contacted your local field applications engineer? If you do not have their contact information, please provide me your details (Company, location, etc) so that I can ask the appropriate person to get in touch with you.
Have you tried using TINA-TI? It is very easy to change the typical released application to fit your custom application. If you have any difficulties in using this tool, let me know and I can help you out.
Best regards,
