Bitslip Timing Model and Parameters
Guidelines for Using the Bitslip Submodule
Set the BITSLIP_ENABLE attribute to TRUE. When BITSLIP_ENABLE is set to FALSE, the
Bitslip pin has no effect. In a master-slave configuration, the BITSLIP_ENABLE attribute in
both modules must be set to TRUE.
To invoke a Bitslip operation, the Bitslip port must be asserted High for one CLKDIV cycle.
In SDR mode, Bitslip cannot be asserted for two consecutive CLKDIV cycles; Bitslip must
be deasserted for at least one CLKDIV cycle between two Bitslip assertions. In both SDR
and DDR mode, the total latency from when the ISERDES captures the asserted Bitslip
input to when the “bit-slipped” ISERDES outputs Q1–Q6 are sampled into the FPGA logic
by CLKDIV is two CLKDIV cycles.
This section discusses the timing models associated with the Bitslip controller in a 1:4 DDR
configuration. Data (D) is a repeating, 4-bit training pattern ABCD. ABCD could appear at
the parallel outputs Q1–Q4 of the ISERDES in four possible ways: ABCD, BCDA, CDAB,
and DABC. Only one of these four alignments of the parallel word makes sense to the
user's downstream logic that reads the data from the Q1–Q4 outputs of the ISERDES. In
this case, it is assumed that ABCD is the word alignment that makes sense. Asserting
Bitslip allows the user to see all possible configurations of ABCD and then choose the
expected alignment (ABCD).
the corresponding re-alignments of the ISERDES parallel outputs Q1–Q4.
