6. The DDR SDRAM wizard automatically creates constraint scripts for the high-
speed DDR SDRAM signals in the top-level design. Therefore, the DDR SDRAM
controller top-level pin names must match what the DDR SDRAM controller
wizard expects. Otherwise, the proper constraints are not made. The following
three settings in the DDR wizard define the pin names to which constraints are
made:
Pin name of clock driving memory (+)
Pin name of clock driving memory (-)
Prefix all DDR SDRAM pins with
Ensure that the DDR SDRAM controller pins at the top-level design adhere to the
naming conventions defined in these settings.
7. For the constraint scripts to work correctly, you must name some 1-bit DDR
SDRAM signals using bus notation at the top-level design, if the top-level design is
a BDF schematic file, which means they require a suffix of [0]. Locate the following
example pins and rename with a [0] suffix:
clk_to_sdram_p
clk_to_sdram_n
sdram_cs_n
sdram_cke
The pins now have the following names:
clk_to_sdram_p[0]
clk_to_sdram_n[0]
sdram_cs_n[0]
sdram_cke[0]
1
The pin names can change depending on the settings made in step 6 , but they must
have the [0] suffix in the top-level schematic.
