Bash scripts for side tools (EBMC, SymbiYosys, Verilog2SMV) running unable to extract names of several Verilog modules:

For these modules their top level names are empty. Note, that all the scripts have a precondition: top level name is it's first declared module name.

The problem is in the following code:

top_name=$(echo "${line}" | sed -n 's/^module \([a-zA-Z0-9_]*\)[ |(||;].*$/\1/p')
