Calling DDR2/DDR3 Memory Controller in Qsys. In the case of Qsys, you can also set the I/O Standard and Current Strength of the memory interface signal by executing the file _pin_assignemnts.tcl, but the name is too long like _memory_mem_dq[0]. If I change the FPGA pin name to resolve the issue, is there no other way but to manually edit it using Assigenment Editor?

If you have changed the pin names of your FPGA, you can do so by editing _pin_assignemnts.tcl.

In _pin_assignemnts.tcl, edit the following 3 lines as needed.

"original text"
|
set instance_name ""
|
if {![info exists pin_prefix]} {set pin_prefix "mem_"}
|
set qsys_pin_prefix "${instance_name}_memory_"
|

■ Execute TCL without editing ⇒ It becomes like "_memory_mem_dq[0]".

"Editing example"
|
set instance_name ""
|
if {![info exists pin_prefix]} {set pin_prefix "mem_"}
|
set qsys_pin_prefix "qsys_ddr2_"
|

■After editing TCL as shown in the example, execute ⇒ "qsys_ddr2_mem_dq[0]".
