Unable to synthesize swerv_wrapper on ASAP7

[gudeh]

Hi everyone. When I try to synthesize swerv_wrapper as available in the Makefile: "DESIGN_CONFIG=./designs/asap7/swerv_wrapper/config.mk"

Is this design supposed to run successfully? The process was killed with "code 9" on step: 5_3_route

Most likely you ran out of memory. How much ram do you have?

I have 16GB on this PC. Should it be enough?

[maliberty]

How much swap do you have?

gudeh@snowflake:~$ free --giga

which won't fit in 16 Gb + 2 GB of swap.
