cr1901_modernmwk: The -icells param you mentioned to read_verilog works for my needs for now. I don't have the time to look deeply into this right now, but I _feel like_ the backends that use attrmvcp aren't using it properly.21:52
cr1901_modernWhen I run them, all src/loc attributes on all nets are moved to cells b/c of the "n:*" selection tacked on at the end21:53
cr1901_modernWhen I thought the point was to move src/loc from ports to the cells21:53
cr1901_modernerr, move the attributes on the verilog modules ports to the cells driving/driven by the verilog module ports*21:54
mwk... my gut feeling is that they should not be doing that anyway22:28
mwkhmm22:29
cr1901_modernWhat I'm using: attrmvcp -attr src -attr LOC -driven t:$__FACADE_INPAD %x:+[I]22:30
cr1901_modernfor example- this works (both the wire _and_ the cell have to be in the selection)22:31
cr1901_modernfwiw, those attrmvcps in synth_greenpak/coolrunner have always been this way. Makes me wonder if it's syntax changed over time, or a typo was copied22:32
mwk... or someone just didn't care22:32
cr1901_modernwho knows :). I wanted to do the "use attributes for placement and io_type" trick b/c I thought it'd be easier to prototype.22:36
cr1901_modernBut the time it took me to get it working- among other real life things this week- I could've used ECP5's LPF parser for this22:37
