ERROR: [VRFC 10-449] cannot open file "/afs/xxxx/obsfdacmj4ltsh34hqceamceyrcimraog5opt0hdnxd.sdb" for writing

Description

I am unable to run the post Synthesis functional simulation and am seeing the following error.

ERROR: [VRFC 10-449] cannot open file "/afs/btv.ibm.com/data/chips/hss/fx14p/darkhorse/vivado/darkhorse/20162/fpga_top/fpga_top.sim/sim_1/synth/func/xsim.dir/xil_defaultlib/obsfdacmj4ltsh34hqceamceyrcimraog5opt0hdnxd.sdb" for writing

This issue is machine specific and has not reoccurred in other machine environments.

Solution

This error relates to the AFS file system you are using.

The cause of this error is that AFS has a limit on the total length of the names of all files in a directory. 
If the file names are short, you can write approximately 64,000 files to an AFS directory.  If the file names are long, you will hit the directory limit much sooner.

You can work around this issue by using a non AFS directory.
