LogiCORE SPI-4.2 (POS-PHY L4) v8.1 - Virtex-5, MAP "ERROR:Place:293 - The following 4 components are required to be placed in a specific relative placement form."

Description

When targeting Virtex-5, SPI-4.2 design with "Insert IDELAY on RDCLK" feature selected, in MAP, I receive the following error:

"ERROR:Place:293 - The following 4 components are required to be placed in a

specific relative placement form. The required relative coordinates in the

RPM grid (that can be seen in the FPGA Editor) are shown in brackets next to

the component names. Due to placement constraints it is impossible to place

the components in the required form.

IODELAY core_pl4_snk_top0/U0/clk0/rdclk_idel (5, 0) placed

at site IODELAY_X1Y161

IOB RDClk_P (0, 0) placed at site IOB_X1Y161

Empty site required (1, 0) IOB RDClk_N (0, -12) placed

at site IOB_X1Y160"

Solution

This error is due to an issue with MAP and is fixed in ISE 8.2i Service Pack 2.
