set_instance_assignment -name MEMORY_INTERFACE_DATA_PIN_GROUP 18 -to
${dm_pin_name}\[0..1\] -from ${d_pin_name}\[0\]
set_instance_assignment -name MEMORY_INTERFACE_DATA_PIN_GROUP 18 -to
${d_pin_name}\[18..35\] -from ${d_pin_name}\[18\]
set_instance_assignment -name MEMORY_INTERFACE_DATA_PIN_GROUP 18 -to
${dm_pin_name}\[2..3\] -from ${d_pin_name}\[18\]
3. Replace with the following assignment:
set_instance_assignment -name MEMORY_INTERFACE_DATA_PIN_GROUP 9 -from
${d_pin_name}[0] -to ${d_pin_name}[0..8]
set_instance_assignment -name MEMORY_INTERFACE_DATA_PIN_GROUP 9 -from
${d_pin_name}[0] -to ${dm_pin_name}[0]
set_instance_assignment -name MEMORY_INTERFACE_DATA_PIN_GROUP 9 -from
${d_pin_name}[18] -to ${d_pin_name}[18..26]
set_instance_assignment -name MEMORY_INTERFACE_DATA_PIN_GROUP 9 -from
${d_pin_name}[18] -to ${dm_pin_name}[2]
set_instance_assignment -name MEMORY_INTERFACE_DATA_PIN_GROUP 9 -from
${d_pin_name}[9] -to ${d_pin_name}[9..17]
set_instance_assignment -name MEMORY_INTERFACE_DATA_PIN_GROUP 9 -from
${d_pin_name}[9] -to ${dm_pin_name}[1]
set_instance_assignment -name MEMORY_INTERFACE_DATA_PIN_GROUP 9 -from
${d_pin_name}[27] -to ${d_pin_name}[27..35]
set_instance_assignment -name MEMORY_INTERFACE_DATA_PIN_GROUP 9 -from
${d_pin_name}[27] -to ${dm_pin_name}[3]
4. Save the <variation_name>_pin_assignments.tcl file.
The rest of the RTL implementation is similar to a regular QDR II+/QDR II SRAM
interface.
