mithrolitghost: After 45a8af8d71c285e7115112c564e5d46b6c81dd97 I'm still seeing a whole bunch of removals bufg_xxx_r.db files?01:17

litghostmithro: I don't think we care about the mask files, we aren't seeing the segbits disappear01:18
litghostmithro: Does the int_l change look correct, or an instability?01:21

litghostmithro: That's an instability :(  The GFAN0 -> X pips are relatively hard to reliably fuzz01:22
mithrolitghost: Any idea why the ppips_hclk_[r|l].db files are not getting generated?01:29
litghostmithro: I don't think hclk's have ever had ppips?01:33
mithrolitghost: The artix7/ppips_hclk_l.db file must have come from somewhere....01:34
litghostmithro: I'm pretty sure the ppip is wrong, and the pip should be https://github.com/SymbiFlow/prjxray-db/blob/master/artix7/segbits_hclk_l.db#L101:40

mithrolitghost: Could we add INT_L.BYP_ALT1.GFAN0 to the dbf file to stabilize the INT_L fuzzer?21:47
litghostThat isn't what the dbf file does, so no22:03
mithroWhat does the dbf file do?22:05
litghostSets the zero groups22:07
mithroAhh22:08
mithroAny idea what dbf stands for?22:08
litghostI have no idea22:08
