Most flash memories available can run up to 100 MHz. To configure the
Stratix IV GX and GT device at 125 MHz, Altera recommends using a MAX II device
to convert the 16-bit flash memory output at 62.5 MHz to 8-bit configuration data
input to the Stratix IV GX and GT device at 125 MHz.
The PCI Express Electrical Gold Test requires the v2.0 CBB to be connected to the
Device Under Test (DUT). The CBB sends out a 100 MHz signal for 1 ms to indicate
the Link Training and Status State Machine (LTSSM) of the downstream device Under
Test (DUT) to transition to several polling compliance states. Under these states, the
DUT sends out data at Gen1, Gen2 (with -3.5db de-emphasis), and Gen2 (with -6 db
de-emphasis) rates, which can be observed in the scope to confirm electrical signal
compliance. The CBB is DC-coupled to the downstream receiver.
When you use the Stratix IV GX and GT device as DUT, because of being DC-coupled
to CBB with a different common mode level, the Stratix IV GX and GT receiver does
not receive the required V
that implements LTSSM cannot transition to the multiple polling compliance states to
complete the test. Therefore, when testing with the CBB, force the LTSSM
implemented in the FPGA fabric to transfer to different polling compliance states
using an external push button or user logic.
If you use the Stratix IV GX and GT PCIe hard IP block, assert the test_in[6] port of
the PCIe Compiler-generated wrapper file in your design. Asserting this port forces
the LTSSM within the hard IP block to transition to these states. The test_in[6] port
must be asserted for a minimum of 16 ns and less than 24 ms.
