This release of the TWB (TWB 5.1) will support both the v520 and v550, however, only firmware for the v550 is included. Firmware for the v520 will follow in later releases.
Software updates will be available at:
https://support.teseda.com/v550/v550.html
IF YOU HAVE R1 on the V550 READ THIS!
In previous releases, the firmware needed for the tester shipped with the TWB. Now that the TWB supports multiple testers, you will need to download the proper firmware for your target tester and install it where TWB is installed. You can download firmware for your tester from Teseda's support web site: https://support.teseda.com
Even if your tester ships with firmware, you need to download and install a copy with TWB. There are specific use cases, where you will not need local firmware but it is far easier to just download and install the firmware locally.
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.
If you have a TWB release before v5.1, you will need to re-create your projects. If you have a v5.1 release project, you need to recompile you projects.
If you have Beta or Release Candidate (RC) Versions of 5.2, you should delete your projects and re-create them.
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 v5.2.0 Teseda WorkBench software from the Teseda secure website: https://support.teseda.com/
You need a username and password to access this directory. Your v5.2.0 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.
Please do not install new TWB software over an existing install.
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...
1. Open the LMTOOLS by executing the lmtools.exe
file, typically located in the
C:\flexlm directory.
2. 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
This Beta release does not have the documentation
for either the TWB 5.0.0 software nor the V550
Engineering Platform.
The v550 will allow two separate strobe/capture edges per timing domain. The compiler will automatically assign a STIL defined capture event to a domain strobe.
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 new STIL compiler included in TWB now supports full STIL 1999 and 2005 Scan Chains
Multiple Pattern in a Pattern Burst and multiple Pattern Exec in a STIL file are now fully supported.
The compiler also supports Spec and Category blocks and the use of spec variables in timing.
You can now create Shmoo setups without being connected to a tester. Shmoo setups and results can be saved.
See the User's Guide for all the new Shmoo Features.
Chain Plot has been updated and is now a full graphical chain plot.
Under the actions menu are two new menu items:
Import and Export Tester Configuration
These menus allow you to export the non-STIL setup of your project. This includes:
Power Configuration
High Speed Clock Setup
Pin Voltage Setup
When running a test, if you input a Time Scale Factor that is outside of the allowed range, the value will be adjusted to be within the allowed range. No feedback is given when this happens. You can see the allowed range in a tool tip on the Time Scale Factor field.
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.
v550 PMU is not a feature in this release. The DCTM section of the TWB is only for the v520
Voltage limits for the logic are slightly reduced. See the TWB's Pin Voltage screen for a complete range.
Units in Shmoo are different, please be look carefully at the units.
TWB projects and archives cannot be renamed.
