[Himbaechel][XILINX] missing timing file.

[cbalint13]

Hi !

With the new xilinx changes (HEAD) using latest prjxray & prjxray-db leads to build error.

Seems that kintex7/timings/slicem.sdf was never present in the public prjxray-db, is there a way to bring it there (without fuzzing form scratch) ?

Or can this be skipped by nextpnr , given latest changes ?

(x) I am compiling with flags:

       -DHIMBAECHEL_XILINX_DEVICES="xc7a100t;xc7a200t;xc7a50t;xc7k70t;xc7s50;xc7z010;xc7z020" \
       -DHIMBAECHEL_PRJXRAY_DB="/usr/share/xray/database/" \

(x) The error message:

The timing is very rough and ready at the moment (due to fundamental limitations in xray), just copying the files from artix7 is fine (don't rely on the Fmax from nextpnr for now anyway)

Thank you @gatecat !

Will do it so, I close this.
