SAS Test SolutionsQPHY-SAS3

QPHY-SAS3 provides a highly automated and easy-to-use solution for SAS-3 configurations from 1.5 Gb/s to 12 Gb/s.

The QPHY-SAS3 Test Solution provides automated control of the SDA 8 Zi-A and LabMaster 10 Zi oscilloscopes for performing all of the transmitter physical layer tests as described by the T10 SAS-3 specification. This specification covers targets and initiators running at 1.5 Gb/s, 3.0 Gb/s, 6.0 Gb/s, and 12.0 Gb/s.

Serial Attached SCSI (SAS) is the serialized version of the popular SCSI standard. SAS is primarily used for server class storage at speeds of up to 12 Gb/s.

QPHY-SAS3 covers tests from Group 1 (TX OOB Signaling and AC Coupling Requirements), Group 2 (TX Spread Spectrum Clocking (SSC) Require ments) and Group 3 (TX NRZ Data Signaling Require­ments) of the test specification. Additionally, QPHY­SAS3 supports the required SAS3_EYEOPENING measurements.

These capabilities make QPHY­SAS3 an all-inclusive automated test suite that meets the requirements for 1.5 Gb/s, 3.0 Gb/s, 6.0 Gb/s and 12.0 Gb/s SAS transmitter compliance testing.

QPHY-SAS3 Makes Compliance Testing EasyThe use of Spread Spectrum Clocking (SSC) in transmitted signals is an optional feature of the SAS­3 specification. When SSC is enabled, measurements such as frequency modulation rate and deviation must also be verified per the specification. The QPHY­SAS3 software works in conjunction with the deep memory and powerful analysis library of Teledyne LeCroy oscilloscopes to greatly simplify this verification process. Clock recovery circuitry and clock extraction via Phase­Locked Loops (PLLs) is another significant design consideration. Flexible clock recovery options allow for the replication of virtually any real receiver PLL configuration enabling the simulation of “what if” scenarios. Jitter results can be measured exactly as the receiver would see them.

Advanced Debug CapabilityIf a compliance failure is found, Teledyne LeCroy’s SDAIII-CompleteLinQ serial data analysis package is available to help find the root cause quickly and easily. SDAIII-CompleteLinQ has the ability to perform Eye and Jitter measurements on up to four lanes and is fully integrated into the oscilloscope application software. In addition, the software includes tools that provide insight into Eye and Jitter parameters making it easier to identify sources of problems.

SDAIII-CompleteLinQ includes simultaneous multi­lane serial data, eye, jitter, noise and crosstalk analysis, and integrates the Eye Doctor™ II toolkit for equalization and channel/fixture de­embedding and emulation.

Out of Band (OOB) validation ensures that the maximum noise during OOB idle, OOB burst amplitude, OOB offset delta, and OOB common mode delta are all within the specification limits.

Spread Spectrum Clock (SSC) validation requires long memory and specialized analysis functions. QPHY-SAS3 can precisely track SSC profiles through multiple cycles in real time. SSC modulation frequency, deviation, balance and DFDT are all measured.

Tx Emphasis measures precursor equalization ratio (Rpre), postcursor equalization ratio (Rpost), VMA, and VHL using the SAS3_EYEOPENING script.

QualiPHYQualiPHY is designed to reduce the time, effort, and specialized knowledge needed to perform compliance testing on high­speed serial buses.

• Guides the user through each test setup

• Performs each measurement in accordance with the relevant test procedure

• Compares each measured value with the applicable specification limits

• Fully documents all results

• QualiPHY helps the user perform testing the right way— every time!

Compliance reports contain all of the tested values, the specific test limits and screen captures. Compliance

reports can be created as HTML, PDF or XML.

Additional SAS-3 Teledyne LeCroy Oscilloscope Options

ProtoSync links physical layer waveforms, decode annotation and table information, and full transaction layer protocol analysis. Simply touch a decode table entry in the oscilloscope or a packet in the protocol analysis software and all views are automatically synchronized and aligned. 1.5 Gb/s to 12 Gb/s versions of SAS are supported in ProtoSync.

14.1 Gbps 80-bit NRZ and 8b/10b Serial Data Trigger and 8b/10b DecoderUp to 14.1 Gbps true hardware NRZ serial data pattern, symbol, and primitive trigger. The specially-programmed hardware FPGA is constantly monitoring for specified events in realtime and triggering the oscilloscope on every occurrence found. This vastly simplifies and speeds debug of high speed bus systems that rely on NRZ data or 8b/10b symbol encoding.
