| # CLB_MUXF8 Minitest | |
| ## Purpose | |
| This tests an issue related to Vivado 2017.2 vs 2017.3 changing MUXF8 behavior | |
| The general issue is the LUT6_2 cannot be used with a MUXF8 (even if O5 is unused) | |
| ## General notes: | |
| - 2017.2: LUT6_2 works with MUXF8 | |
| - 2017.3: LUT6_2 does not work with MUXF8 | |
| - All: LUT6 works with MUXF8 | |
| - All: MUXF8 (even with MUXF7) can be instantiated unconnected | |
| - 2017.4 seems to behave like 2017.3 | |
