#17 Error during the Synthesis Step Issue opened by harikumar27399 I have tried using the OpenLane flow for the aardonyx SoC developed at IIT Madras, India. An error is encountered during the synthesis step using Yosys and ABC. The error message reads as below: 67.1. Executing OPT_EXPR pass (perform const folding). terminate called after throwing an instance of 'std::out_of_range' what(): Cell::getParam() [ERROR]: during executing: "yosys -c /openLANE_flow/scripts//synth.tcl -l /openLANE_flow/designs/aardonyx/runs/28-07_19-08//logs/synthesis/yosys.log |& tee >&@stdout" [ERROR]: Last 10 lines: child killed: SIGABRT error.log yosys.log efabless/openlane
