Test 6.7.1.9: Phy Capabilities Bits – G1 WITH SSC
Purpose
To verify the contents of the DUT's Phy Capabilities G1 WITH SSC bit.
References

6.7.4.2.3.3 SAS Standard
Resource Requirements
●
A Protocol Generator/Analyzer capable of transmitting and receiving SAS OOB signals
and SAS 2.0 Speed Negotiation.
Modification Record

Discussion
A G1 WITH SSC bit set to one indicated that the phy supports G2 (i.e., 1.5 Gbps) with
SSC. A G1 WITH SSC bit set to zero indicates that the phy does not support G1 with SSC. This
is an informative test and applies only if the DUT supports SSC signaling.
Test Setup
●
The DUT and the Testing Station are physically connected the the DUT is powered off.
Procedure
1. Power on the DUT.
2. The testing station is instructed to transmit COMINIT/COMRESET to the DUT.
3. The DUT is expected to respond with COMINIT/COMRESET.
4. The testing station is instructed to transmit COMSAS to the DUT.
5. The DUT is expected to respond with COMSAS.
6. Upon reception of COMSAS from the DUT, the Testing station is instructed to transmit
D.C. Idle for one RCDT. The DUT is expected to do the same.
7. Following RCDT, the testing station is instructed to transmit ALIGN(0) primitives at 1.5
Gbps for one SNTT. If the DUT supports 1.5 Gbps signaling, it is expected to do the
same. If the DUT does not support 1.5 Gbps signaling, it should continue to transmit
D.C. Idle.
8. The Testing station is then instructed to transmit D.C. Idle for one RCDT. If the DUT
supports 3.0 Gbps. The DUT is expected to do the same.
9. Following RCDT, the testing station is instructed to transmit ALIGN(1) primitives at 3.0
Gbps for one SNTT. If the DUT supports 3.0 Gbps signaling, it is expected to the same.
10. The Testing Station is then instructed to transmit D.C. Idle for one RCDT. The DUT is
expected to do the same.
11. The Testing Station is the instructed to transmit its Phy Capabilities bits indicating
support for all speeds and SSC settings. The DUT is expected to transmit it's Phy
Capabilities Bits.
Observable Results
●
Verify the contents of the G1 WITHOUT SSC bit from the DUT's Phy Capabilities bits.
Possible Problems
●
