Why can PLL + LPDDR2 compile success in Quartus 17.1, but fail in 13.1?

Device:5CEBA4U15I7N

The reference clk of lpddr2​ is connected to the output of pll, the project can compile success in 17.1 but failed in 13.1.

Hi sir,

Probably it is due to an issue for that old version. The 13.1 obsolete quartus version is obsoleted. Please use newer version.
