What can I do with the following error during yosys-abc run?
5.23.1.1. Executing ABC.
Running ABC command: <yosys-exe-dir>/yosys-abc -s -f <abc-temp-dir>/abc.script 2>&1
ERROR: ABC: execution of command "/build/bin/yosys-abc -s -f /tmp/yosys-abc-zqwvu9/abc.script 2>&1" failed: return code -1.
Is this because of extra big design? :
5.23.1. Extracting gate netlist of module `\crc32' to `<abc-temp-dir>/input.blif'..
Extracted 1308837 gates and 1311238 wires to a netlist network with 2400 inputs and 32 outputs.

09/07/2021, 12:46 PMHere it is. I'm trying to run flow at design with >10^6 cells. May be this is the reason. Smaller designs passed successfully.

09/07/2021, 12:58 PMIncrease the memory and try it
export DOCKER_MEMORY=16gb
set this before make mount

09/07/2021, 1:03 PMI run docker at host with 72GB of memory. I hope all this memory is available in docker container. I didn't catch where should I set this variable? Should I set it before docker container run or as parameter to docker run?

09/07/2021, 1:13 PMIn terminal run below command where OL lanuched:
$export DOCKER_MEMORY=32gb
$make mount

09/07/2021, 2:13 PMThe docker documentation says:
By default, a container has no resource constraints and can use as much of a given resource as the host’s kernel scheduler allows.

09/08/2021, 12:14 PMI'm also struck with such big design. Try with Open-Road-flow-scripts. Else do macro hardening and integrate the design. split into sub-level design and do chip integration.

09/08/2021, 12:20 PMThanks. I have the same idea 🙂 Do you have any metrics of area optimization? For one of my design (~17000 gates) I got ~70% density at Innovus and at least 20% at OL.
