Arty A7 100T genfasm crash (in counter_test)

[Skydive]

I was told on IRC that setting VPR_SEED may be a workaround. I've repeated the command, after deleting the build folder each time: TARGET="arty_100" make | tee <LOGFILE> 1) export VPR_SEED="--seed 1341221332" 2) export VPR_SEED="--seed 12345" 3) unset VPR_SEED At the end of each log:

Begin loading /opt/symbiflow/xc7/install/bin/vpr_common: line 111: 26523 Killed                  genfasm ${ARCH_DEF} ${EBLIF} --device ${DEVICE_NAME} ${VPR_OPTIONS} --read_rr_graph ${RR_GRAPH} $@
make: *** [Makefile:40: build/top.fasm] Error 137

I hope this aids efforts to fix this problem. log-seed-unset.log log-seed-1341221332.log log-seed-12345.log

Sorry I was mistaken about the error you have. The error you are seeing is in genfasm, not in routing. I'll take a look this week.

Can you please post the ".net", ".place" and ".route" files for you target? I believe I know the issue, and want to replicate what you are seeing.

This is for the unset VPR_SEED top.place top.route top.net

So I've identified the problem. The genfasm step for the 100T currently consumes ~7 GB of RAM, and I believe you mentioned that you had ~7 GB of RAM total. Lowering the peak memory usage is something we are working on, but it isn't something we have a concrete path forward on. Sorry for the inconvenience.
