Frequently Asked Questions
1. What is NEDA Desktop Edition?
A: NEDA Desktop Edtion is a instant STDF analyse tool, it can extract STDF directly with a fast speed, then plot statistical distributions and generate wafer maps.
2. How to get NEDA trial license?
A: We provide 30 days trial license to all new users to let them learn about NEDA features. There are 3 ways to get trial license
1. If you have internet access, you can open NEDA directly, goto menu [Help - License - Activate online], input required information and get trial license.
2. Leave message with Machine Code on our contact page
http://www.nornion.com/contacts.aspx
3. Send your machine code to
support@nornion.com.
3. What is NEDA Machine code and how to get it?
A: NEDA machine code is a hardware related serial number, we will generate license based on it. Start NEDA, goto menu [Help - License - Machine code] to get it.
4. What could affect NEDA extraction speed?
A:1. Hardware of your computer
2. STDF density, even same file size STDF files will have different extraction speed due to its data density.
3. If you are openning STDF files from a net driver (share folder), your network speed will be the main limitation of extraction.
4. NEDA configuration, it will have fastest extraction speed if you set NEDA to identify TEST by TEST_NUM (identify TEST by TEST_NAM or TEST_SEQ will have lower speed).
5. What types of license does NEDA Desktop Edition support?
A: NEDA has 2 types of license:
1. Standalone license: every computer installed NEDA needs a dedicated license.
2. Floating License, every user use NEDA on their own computer and retreive license from floating license server. Total floating license quantity limits user numbers that online at same time.
Both types of license can support annual or perpetual.
6. Can perpetual license use upate new version of NEDA？
A: Yes, as long as your license is valid, you can upate latest version of NEDA and experience new features.
7. Can NEDA edit STDF files?
A: Yes，you can use NEDA to update STDF MIR record, but only support MIR record updating, no other records could be updated.
8. How to fix "GDI+ generic error" when plot districution?
A: Grant read & write permission to Chartlet & Exports folders in NEDA installation path，NEDA will create temporary files in these folders.
9. Why can't NEDA exract STDF data to database?
A: NEDA was designed as an instant analysis tool to provide faster extraction speed, in order to achive this, all data was extracted and computed in memory.
NEDA provides parser library, customer can use it develop their own script to extract STDF data to database.
It also can be used to develop scripts to convert STDF to CSV/TXT data or wafer map files in Excel/TXT format
You can also used to develop auto script to update STDF MIR record with information retrieved from MES.
You can find
development manual and
demo code in DEV folder in NEDA installation path.
10. How to transfer NEDA license to different computer?
A: Sometimes you may need to transfer license to different computer, and update computer HW or OS will also cause license become invalid.
Please remember to release license on old computer before you do any HW or OS change.
Got to Menu [Help - License - Release], and send .rls file to support@nornion.com,
we will give you confirmation to install NEDA on new computer, we will generate new license based on your new machine code and send to you.
11. Can NEDA write data to STDF?
A: We provide another library (nSTD Writer) which could write memory data to STDF file stream. And it you can also use it to develop
auto script to convert other format data (csv, txt, binary etc) to STDF.
You can go to DEV folder in NEDA installation path and find
Development Manual and
demo code.
