5.3.2 fixes an issue in the shmoo found in previous 5.3 releases. When varying internal power supply settings during shmoo on a previously saved project, TWB would issue an exception and fail to complete the shmoo test. 5.3.2 allows the user to properly run shmoo tests on saved projects.
The 5.3.1 build has the same features of 5.3 with some additional enhancement from early customer feedback. These enhancements include:

IF YOU HAVE R1 on the V550 READ THIS!
If you have a v550 loaded with R1 firmware you will need to update your firmware with R2 firmware twice.
The block layout of the flash changed between R1 and R2, because of this you will need to update the firmware and FPGA images twice.
Follow the procedures in the User's Guide for updating firmware. The first time you attempt an upgrade you may get an error message saying the TWB timed out while waiting for a reboot. Manually reboot your tester.
Even if you did not have to manually reboot your tester, you will need to update the firmware again. Do not try running tests until you do two updated.
Projects from prior versions of TWB will be migrated to the latest version as soon as the project is opened. This can not be undone, so TWB will offer you the option to archive the project in its current version. Once the project is archived, the project will open in 5.3 and be atuomatically migrated.
This section previews the steps you must take to install your V550 hardware and TWB software, and also to set up your FLEXlm license server. Additional documentation, available at the Teseda public ftp site (ftp.teseda.com/pub/), explains what's involved in each of these steps in more detail.
To install your V550 system and TWB software:
Obtain a FLEXlm license file from Teseda. The getLicense.pdf document at the Teseda public ftp site (ftp://ftp.teseda.com/pub/) explains how to do this.
Download and install the v5.3 Teseda WorkBench software from the Teseda secure website: https://support.teseda.com/
You need a username and password to access this directory. Your v5.3 software release notification email should provide this information.
Download the compressed FLEXlm manager files from the Teseda secure support site. You need a username and password to access this directory. See the getLicense.pdf for details.
Set up a FLEXlm service on your network. See the Install_Guide.pdf for details; this PDF file is also available at ftp://ftp.teseda.com/pub/
The following NOTES describe important information you need to know before installing the TWB software.
This release is intended to be installed solely for the V500 Series (TWB 5) software, but you may also install the software as a complete installation in itself. DO NOT install over existing V500 Series software 4.x and below.
EDITING YOUR twb.lax FILE Since this release is really a complete re- install of your V500 Series TWB software, any changes you have made in the twb.lax file will be saved, but cannot be readily used. If you have modified your twb.lax file, you may want to merge your changes by hand from the twb.lax.old to the newly-installed twb.lax file.
RE-READING THE teseda.lic LICENSE FILE AFTER RECEIVING A NEW LICENSE If you receive a new teseda.lic license file, and you have the FLEXlm license service running locally on your workstation, you must re-read the license file before you can successfully launch the TWB. First, copy the new teseda.lic file to your TWB install directory, then complete the following steps:
In Windows..
Open the LMTOOLS by executing the lmtools.exe (Typically located in the C:\flexlm directory).
In the LMTOOLS dialog box, activate the Start/Stop/ReRead tab and then click the "Re Read License File" button. Once the license file is read this message appears: Reread Server License File Completed
In Linux/Solaris...
As "root" user, execute the following command: /etc/init.d/teseda_lmgr reread
Projects from prior versions of TWB will be migrated to the latest version as soon as the project is opened. This can not be undone, so TWB will offer you the option to archive the project in its current version. Once the project is archived, the project will open in 5.3 and be atuomatically migrated.
It is important to note that prior test results from TWB 4.X and TWB 3.X will not be migrated to your new project. Chain plots on tests from TWB 5.X will show up a all green. The test must be re-run to gather accurate results.
Shmoo settings will not be migrated to version 5.3. You will need to re-build any shmoo tests in version 5.3 by manually recording your settings and reapplying them.
The Precision Period capability was introduced in version 5.2 (See description below), but in that version only one period could be chosen for the project. Version 5.3 expands those capabilities so any pattern in the project can have the precision period. There is some additional time required, in the milisecond range, to switch the period between patterns. For this reason, shmoo tests that vary the period will take longer to execute.
While the period precision is ensured with this option, the edge timing may vary because these timings are derived from the period. For this reason, the user has the ability to choose between edge precision and period precision on a pattern by pattern basis when running a test flow.
Precision Period:
Normally, the V550 is only able to achieve periods that fall on a 10ns boundary. If a user’s STIL test requests a 65ns period, the period will be rounded up to the nearest 10ns which would be 70ns, however the clock and data edges will remain as set in the test. For some tests, this rounding modification of test periods may not be acceptable. The Precision Period Frequency feature enables the V550 to run the test at the exact 65ns period.
The V550 now has the ability to generate a fail trigger signal and a fail latch signal for interfacing with failure analysis equipent. The vector fail signal will produce a pulse when a failure, or the user defined nth failure, is encountered in the pattern. The vector fail latch will produce a sustained high when the user defined nth signal is encountered.
TWB 5.3 reintroduces the Applications Programming Interface (API) and the Command Line Interface (CLI) for automating testing and interfaces with other tools. Those who were using older versions of TWB that had the API and CLI can now benefit from the improvements that have been made to TWB since the API and CLI were discontinued.
Several improvements have beem made to facilitate easier navigation and understanding of pattern data:
An automatic failed-signals only filter.
No results will be produced in the results panel if the test was not run.
Ability to navigate to next failure in displayed signals.
Group signal masking.
In the releases of 5.x, the firmware is no longer shipped by default. You must download and install the firmware for the tester you are using.
The utility power supply has a nominal 5 volt output.
Power Supplies not “safed” on a hard reboot until the system comes back up. Please do not try to change the DUT until the system is rebooted or turned off.
Voltage limits for the logic are slightly reduced. See the TWB's Pin Voltage screen for a complete range.
The self test for the IDDQ module will fail, even though the Monitor is working correctly.
