7.1i ISE - "ERROR:HDLParsers:3264 - Can't read file "<schematic_file>.vhf": No such file or directory"


General Description:

When I open a project containing a schematic source with a Test Bench Waveform (.tbw) file, the following error occurs in the console window.

"ERROR:HDLParsers:3264 - Can't read file "<project_path>/<schematic_name>.vhf": No such file or directory

ERROR:HDLParsers:3208 - Empty project file <project_path>/<tbw_name>_bencher.prj"


The .vhf or .vf file is the intermediate HDL netlist for the top-level schematic that is pointed to by the .tbw file. The .tbw file references the intermediate HDL file for hierarchical dependence. However, if the Cleanup Project Files process is run on a design, this intermediate HDL file is deleted.

You can ignore the error. Opening the .tbw file or running a process related to it causes the automatic regeneration of the intermediate HDL netlist.

This error occurs when opening the pong, watch_sc, and watch_sc_cr2 example projects. The Cleanup Project Files process is run on all ISE example designs before software release.
