| dkozel | I feel like I've seen a demo of a *lot* of riscv cores crammed into an ECP5. Does anyone know who was doing that? It was a silly number, hundreds of cores IIRC | 07:12 |

| kitten_nb_five | Hello. I am not sure if i found a bug and where to report it (yosys or nextpnr). I wanted to use the DTR-primitive (temperature readout) on ECP5 and found that the names of the in- and outputs do not match what is written in the Lattice FPGA Library Reference. I had to search trough github to find the correct names. Is this normal or should the project use the names from the Ref Manual? | 18:49 |
| daveshah | They should match Diamond | 18:50 |
| daveshah | Let me check the Verilog primitives in Diamond | 18:50 |
| kitten_nb_five | Diamond is the official Lattice tool i assume? | 18:50 |
| daveshah | Yes | 18:51 |
| kitten_nb_five | fyi: in the Reference Manual it is written START_PULSE and DTR_OUT, but yosys/nextpnr uses STARTPULSE AND DTROUT0-7 | 18:51 |
| daveshah | And it looks like it does match the verilog sim model | 18:51 |
| daveshah | So the reference manual is wrong | 18:51 |
| kitten_nb_five | okay, maybe i got an old version. thank you for this quick information! | 18:52 |
| kitten_nb_five | btw, in my opinion a few words of "what does this primitive do?" in the nextpnr-ecp5 Primitive Support List would be a good idea - or not? Should i make a pull-request? | 18:53 |
| daveshah | Yeah, go for it | 18:53 |
| kitten_nb_five | ok, will do soon | 18:54 |
| daveshah | Sorry, I still need to review 504 too, I will try and do that tomorrow | 18:54 |
| kitten_nb_five | no problem :) | 18:54 |
| kitten_nb_five | i am afraid i messed something up on my fork of nextpnr because i commited to master directly for the first pull request. is there a way to move this one to a separate branch using the website? | 19:31 |
| daveshah | Don't know, but feel free just to add it as another to the current pull request | 19:37 |
| kitten_nb_five | yeah ok, i will try. still new to github... | 19:38 |
| kitten_nb_five | ok, i think i cannot revert commits using github. i made a new pull-request (#506) but it contains also the modifications for the first one. i apologize for the mess. :( feel free to edit/delete/discard/whatever. i will stop here and wait for advice. | 19:46 |
