tux3 | ERROR: Found error in internal cell \top.$auto$alumacc.cc:485:replace_alu$13245.A_conv ($pos) at kernel/rtlil.cc:867 | 23:18 |
---|---|---|
tux3 | Does that look like something I should bother reducing/reporting, or just my code being exceptionally dodgy :/ ? | 23:18 |
az0re | Yes, please! | 23:21 |
ZirconiumX | That's a bug, so report it | 23:21 |
ZirconiumX | Especially since it seems to come from alumacc. | 23:21 |
ZirconiumX | There's bugpoint if you want to lazily reduce it. | 23:22 |
az0re | Some sort of port width mismatch? | 23:22 |
ZirconiumX | We'd have to see the cell dump to tell | 23:25 |
tux3 | Hhm I can't get bugpoint to do anything, I just get things like "Cannot reprocess_module" or "Module is used with parameters but is not parametric!" | 23:37 |
tux3 | Maybe the last few lines of the Yosys log have something interesting in them, while I fight bugpoint: https://paste.debian.net/1146837/ | 23:41 |
tpb | Title: debian Pastezone (at paste.debian.net) | 23:41 |
tux3 | (Note the crossbar I stole from https://github.com/ZipCPU/wb2axip/) | 23:41 |
tpb | Title: GitHub - ZipCPU/wb2axip: Bus bridges and other odds and ends (at github.com) | 23:41 |
ZipCPU | tux3: Which bus? How many masters? How many slaves? | 23:42 |
tux3 | Axi4-lite, 2 masters, "2 slaves" only one of which is not hardwired to zero | 23:43 |
ZipCPU | You can't hardwire a slave to zero--it's a protocol violation. Just leave the address unmapped instead. | 23:43 |
tux3 | Oh. It's a violation if it's just never ready? | 23:44 |
ZipCPU | Yes. It'll cause the whole bus to collapse if it's ever accessed | 23:44 |
tux3 | Oh right, I'm planning to add something on the other side of that bus, I was just in between two commits =] | 23:45 |
ZipCPU | If you don't map the address in in SLAVE_ADDR/SLAVE_MASK, then it'll never get accessed and a bus error will be returned instead | 23:45 |
tux3 | Makes sense | 23:45 |
ZipCPU | Don't know about any yosys bug when using it though. Haven't had a problem with it. (Yet) | 23:47 |
mwk | ... hmmm | 23:50 |
mwk | why is that an error | 23:54 |
mwk | tux3: what version of yosys are you using? | 23:57 |
tux3 | master | 23:58 |
tux3 | It worked a few days ago actually, I've started a bisect | 23:58 |
