New Traffic Generator is the Ideal Tool for Speeding Your Design to Completion

SAN JOSE, Calif. (February 25, 2002) -- The PacketMaker™ is a highly flexible, bus traffic generation tool that has been designed expressly for device and controller developers. It is the first for the Serial ATA bus. PacketMaker will be demonstrated at the Intel Developers Forum and will begin shipping in March 2002.

"Traffic generators simulating a host or a device are essential tools for designers in the development community working with emerging buses and are natural companions for our well-established line of Bus Doctor™ Analyzers," says Dale Smith, president of Data Transit.

This new traffic generator is comprised of a Windows-based application and a hardware pod. The pod, which connects to the PC via a USB 2.0/1.1 port, employs a common graphical interface for all the supported buses. The interface is very intuitive and allows for rapid packet design—just point, click and modify. A unique three-row horizontal display format means that navigating and recognizing the sequencing and field values becomes quite easy.

Three Creation Modes
Packets may be created in one of three modes. The first mode allows the user to only employ legal sequences and field values. The second mode ensures that the sequences are legal, however the user may use illegal field values. Finally in Free-form mode the user may put the packets together without restrictions. Also, this mode allows illegal 10b codes to be sent to create disparity, coding and primitive errors.

The interface allows for easy packet insertion, deletion and re-ordering. After the packets have been completed, the user may send them out across the bus as either a single occurrence or in a loop. Packets may also be saved and recalled for future use.

Command Field values can be selected numerically by OpCode, or alphabetically by name. All symbolic lists are sorted both ways. Values for the fields may be entered in hex, binary, decimal, ASCII or symbolically. Other featuresinclude hardware handling of Real-Time Primitive Handshaking, generating any Frame Information Structure (FIS), selecting commands by name or OpCode, selecting feature values by name or OpCode and maintaining Synch/Align transmission during packet upload.

Data Transit designs, manufactures and sells the Bus Doctor line of protocol analyzers. These analyzers work with ATA/ATAPI, USB 1.1 & USB 2.0, SCSI-1 through 320, 1394a, PCI thru PCI-X, PCMCIA, Compact Flash, Cardbus, Fibre Channel, Gigabit Ethernet, Infiniband and Serial ATA. They can also perform Logic Analysis.
