kintex-7 and lpddr2

I have a kintex-7/lpddr2 design. Last August (prior to pcb release) I was able to verify pin assignment constraints via vivado (saved xdc file is attached).

Now the controller type for lpddr2 (via vivado/mig interface generator) is not an option?

I notice the lpddr2 device is not listed under virtex-7 nor kintex-7 supported devices in this link

https://www.xilinx.com/products/technology/memory.html#externalMemory

Was this option changed between then (9/18) and now? Please advise...

V/R,

Greg

LPDDR2 is supported by K7. Did you check it in MIG IP?

It doesn't appear in the MIG's memory selection (see attachment)....

Is the target language VHDL in your project? Please change to verilog and have a try.
