1.6. Test Results for Stratix V and Arria 10 FPGA

Table 7.  Results Definition

Result

Definition

PASS

The Device Under Test (DUT) was observed to exhibit conformant behavior.

PASS with comments

The DUT was observed to exhibit conformant behavior. However, an additional explanation of the situation is included, such as due to time limitations only a portion of the testing was performed.

FAIL

The DUT was observed to exhibit non-conformant behavior.

Warning

The DUT was observed to exhibit behavior that is not recommended.

Refer to comments

From the observations, a valid pass or fail could not be determined. An additional explanation of the situation is included.

The following table lists the results for test cases CGS.1, CGS.2, ILA.1, ILA.2, ILA.3, TL.1, and SCR.1 with different values of L, M, F, K, subclass, data rate, sampling clock, link clock, and SYSREF frequencies.

The following figure shows the SignalTap II waveform of the clock count from the deassertion of SYNC~ to the assertion of jesd204_rx_link_valid signal, the first output of the ramp test pattern (DL.3 test case). The clock count measures the first user data output latency.
