Test 6.7.1.14: Phy Capabilities Bits – Reserved Bits

Purpose

To verify that the Phy Capabilities Bits 14 through 30 are set to zero.

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

06-25-2007: Initial Draft (Michael Davidson).

06-29-2007: Fixed references, changed title numbering (Michael Davidson).

07-20-2007: Expanded procedure (Michael Davidson).

08-01-2007: Removed irrelevant information from the discussion. Corrected
title/discussion for new capabilities naming conventions (Michael Davidson).

Discussion

Table 88 defines the SNW-3 phy capabilities. For each bit defined as reserved, the phy

shall transmit a zero (i.e., D.C. Idle) and shall ignore the received value. Byte 1, bits 1 and 0; and
byte 2 are reserved.

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.
