Serial IO Analyzer Sweep Parameter entry problem

[rs2015]

I am using the Vivado 2015.4 Serial IO Analyzer.

I would like to perform a sweep to vary the RXCDR_CFG parameter, which is an 18 digit hex number (72 bits).

However, I get the following error:

But this is the default value that the tool shows:

What is the reason for this test? can you get the required setting for RXCDR_CFG from GT wizard?

We're having trouble with PHY errors on our SATA port.  I'm investigation the configuration's effect.

I found a work-around:

1. create a sweep with one parameter, such as RXTERM

2. right-click on sweep and select properties

3. Under the PROPERTIES tab, select ITERATION_SETTINGS and enter the sweep parameters, e.g.

{DRP.RXCDR_CFG  0388008BFF40100008} {DRP.RXCDR_CFG  03800023FF40200020} {DRP.RXCDR_CFG  03800023FF10400008}
