For some Sink core configurations (Global Clocking with IDELAY inserted on RDClk), the following errors might occur in Map:
"ERROR:PhysDesignRules:1613 - IDELAYCTRL not found for clock region CLOCKREGION_X1Y3. The IODELAY block core_pl4_snk_top0/U0/io0/dpa2/dpa_top0/DATAPAIR12/SLAVE_DELAY has an IDELAY_TYPE attribute of either FIXED or VARIABLE. This programming requires that there be an IDELAYCTRL block programmed within the same clock region"
This is a known issue with Map and the IODELAY_GROUP contraint.
To work around this problem, do the following:
1. Comment out the following constraints in the UCF file:
