kitten_nb_five | hello. just to make sure, is there something special to think about for a READ from an INOUT? for a write i need to enable the output that is tristated (16'hzzzz), but for a read i can simply assign the value to a reg [15:0] - or not? Lattice ECP5, Yosys and nextpnr | 19:11 |
daveshah | Yeah a read should just work fine like that | 19:12 |
kitten_nb_five | ok, thank you. | 19:12 |
*** matthuszagh has joined #yosys | 19:19 | |
matthuszagh | hello. is it possible to read a spice netlist with yosys? I'm only seeing a command to write a spice netlist | 19:20 |
Lofty | matthuszagh: what would Yosys do with such a thing? It's not a SPICE program | 19:40 |

matthuszagh | Lofty: fair enough. just thought it might since it can write spice netlists. the use case is that a tool called netlistsvg can read yosys json netlists to draw schematics. i thought it might be possible to use this + yosys to draw ngspice netlists. but to your point, this really isn't yosys's use case | 20:18 |
Lofty | It would be useful for it to output SPICE netlists after e.g. ASIC synthesis, but no real use in taking in SPICE netlists | 20:19 |
Lofty | Same reason why Yosys doesn't support things like the Verilog pmos/nmos statements | 20:20 |
matthuszagh | Lofty: ah ok that makes sense. thanks for clarifying | 20:20 |
