impact : ERROR:Bitstream:2 - The input file "xxx.msk" does not exist.


When theVerify option used to check the downloaded bitstream in the FPGA, the following Error is observed:

ERROR:Bitstream:2 - The input file "xxx.msk" does not exist. Please check that the specified location is correct and that the bitstream was successfully created.


This Error is seen if the readback option is not enabled when creating the bitstream along with the mask file creation.

To generate the .msk file in the ISEsoftware GUI go to Generate Programming File -> Properties -> Readback Options tab, and ensure you have selected the option "Create Readback Data files". Also, select the option "Create Mask File".

After generating the bitstream, look for the mask file (.msk) in the iMPACT project directory to complete the verification of the configured bitstream with the original bitstream.
