Steps to reproduce failure:

# clone verilog sources:
git clone https://github.com/fontamsoc/hw.git
cd hw
git checkout symbiflow_support

# prerequisite:
ln -snf pu32-nexys4ddr/litedram/litedram.hex litedram.hex

symbiflow_synth -t nexys4ddr -v pu32-nexys4ddr/nexys4ddr.v -d artix7 -p xc7a100tcsg324-1 -x pu32-nexys4ddr/nexys4ddr.xdc &>/dev/null
symbiflow_pack -e nexys4ddr.eblif -d xc7a100t_test &>/dev/null
symbiflow_place -e nexys4ddr.eblif -d xc7a100t_test -n nexys4ddr.net -P xc7a100tcsg324-1 &>/dev/null

echo $?

I ran symbiflow_place without &>/dev/null and got following output:

oh, OK so it failed on https://github.com/SymbiFlow/symbiflow-arch-defs/blob/master/xc/xc7/toolchain_wrappers/symbiflow_place#L24 we'll have to take a look at this. Can you file an issue in https://github.com/SymbiFlow/symbiflow-arch-defs? So it is not lost.

Thanks
