Syntax error when synthesizing OpenSSD Vivado Project

[HyunwooKim2]

When I tried to synthesize OpenSSD Vivado project, I met error messages as shown below.

ERROR: [Synth 8-2715] syntax error near ? [d:/Git/openssd_error_replay/Cosmos-plus-OpenSSD/project/Predefined/2Ch8Way-1.0.0/OpenSSD2_2Ch8Way-1.0.0/OpenSSD2.srcs/sources_1/bd/OpenSSD2/ip/OpenSSD2_V2NFC100DDR_0_0/src/SDPRAM_9A16x9B16/blk_mem_gen_v8_2/hdl/blk_mem_gen_v8_2.vhd:387]

But I successfully resolved this problem thanks to the OpenSSD development team.
The solution is,

1. Click "Project Settings" button in "Flow Navigator".
2. Click "IP" on left pane of the pop-up window.
3. Click "Add Repository..." button and choose appropriate path to IP repository. In my case, the path was "Cosmos-plus-OpenSSD\project\Predefined\2Ch8Way-1.0.0\IPRepo-1.0.0". (By default, IP repository points wrong path like ".......\IPRepo".)
   
4. And then, click "OK" button to apply repository path.
5. Right click on "Design Sources -> OpenSSD2 (OpenSSD2.bd)" in hierarchy of "Sources" tap (located at left-top side of "Project Manager" pane) and choose "Reset Output Products..." in the menu.
   
6. And then, right click on "OpenSSD2 (OpenSSD2.bd)" again and choose "Generate Output Products..." in the menu.
   
7. After all, re-run the synthesize (by using "Run Synthesis" button in the "Flow Navigator").

I successfully synthesized, implemented, and generated bitstream by using this way.
If there's any problem, please leave a comment.
