Conflicting bits in baselitex-nexys-video test during bitstream generation

Open acomodi opened this issue 3 years ago • 0 comments

The baselitex-nexys-video test is producing the following error:

prjxray.fasm_assembler.FasmInconsistentBits: FASM line "CLBLM_R_X41Y168.SLICEM_X0.BLUT.DI1MUX.DI_CMC31" wanted to clear bit (5248, 36, 20) but was set by FASM line "CLBLM_R_X41Y168.SLICEM_X0.BLUT.DI1MUX.BI"

This might be due to some corner case that enables a wrong intra-site routing, or could also be a wrong FASM features assignment in the slice pb_types.

Until the bug is found and fixed either in the pb type definition or VPR, the following lines should be commented out: https://github.com/chipsalliance/fpga-tool-perf/blob/main/project/baselitex-nexys-video.yaml#L28-L29
