kem_FYI, I believe the switches in the rr_graph.xml need to match (exactly) those in the arch.xml. A mismatch may be why VPR is crashing with non __vpr_delayless_switch__ switches.15:53
daveshahkem_: thanks, that makes sense. I experimented a bit but I don't think I ever got them exactly matching15:55
kem_daveshah: I'd probably try asking VPR to dump an RR graph for your arch.xml and looking/copying the switches from the generated rr_graph.xml15:56
*** digshadow has quit IRC17:38
mithrokem_: Yeah, we are taking that approach but digshadow-c was modifying the switches18:00
